View New Commercial Inventory What Are the Published Towing and Payload Ratings for Ram 2500 and 3500 Cummins Diesels? The Ram Heavy Duty truck lineup is engineered from the ground up for extreme physical endurance. At the heart of this capability sits the legendary 6.7L Cummins Turbo Diesel Inline-Six engine, available in two distinct states of tune across the 2500 and 3500 series. Understanding how torque delivery, rear axle ratios, frame construction, and suspension design interact is essential when configuring a vehicle for commercial hauling. In the Ram 2500 HD, the Standard Output 6.7L Cummins Turbo Diesel generates 370 horsepower and an impressive 850 lb-ft of low-end torque. Combined with a robust hydroformed steel frame and standard rear coil spring suspension (or optional rear air suspension), the Ram 2500 diesel achieves a maximum conventional towing capacity of up to 19,990 lbs and a maximum payload capacity of up to 3,150 lbs depending on cab configuration and axle ratio. The five-link rear coil suspension provides a refined ride quality when unladen without compromising heavy bumper-pull trailer stability. When your commercial operations require extreme gooseneck or 5th-wheel trailering, the Ram 3500 HD steps into a league of its own. Equipped with the High-Output (HO) version of the 6.7L Cummins Turbo Diesel paired exclusively with the heavy-duty AISIN 6-speed automatic transmission, output surges to 420 horsepower and a class-dominating 1,075 lb-ft of torque at just 1,800 RPM. In dual-rear-wheel (DRW) 4x2 regular cab configuration with a 4.10 rear axle ratio, the Ram 3500 boasts a maximum towing limit of 37,090 lbs and a GCWR of 43,000 lbs. Crucial to these extreme towing figures is Ram's factory-integrated 5th-Wheel/Gooseneck Prep Package, which provides structural cross-members welded directly to the frame, integrated bed pucks, and a 7-pin trailer harness mounted inside the pickup box. Furthermore, the Ram 3500 utilizes hot-as-rolled 50,000 PSI high-strength steel frame rails with extra cross-members and heavy-duty rear leaf springs designed to handle massive pin weights up to 6,840 lbs. Whether you need to transport skid steers, excavators, agricultural livestock, or multi-car flatbeds across Kansas, exploring our New Vehicle Listings allows you to filter specifically by axle ratio, dual-rear-wheel configurations, and Cummins engine outputs. Cargo Capacity and Payload Specs of the 2025 Ram ProMaster 3500 High Roof While heavy-duty trucks dominate the towing arena, the 2025 Ram ProMaster 3500 High Roof takes top honors when interior volumetric efficiency, rapid cargo access, and mobile workspace productivity are the primary metrics. Built on a unique front-wheel-drive (FWD) unibody platform, the ProMaster eliminates the heavy central driveshaft and rear differential housing found in traditional rear-wheel-drive work vans. This architectural engineering breakthrough allows for an industry-leading ultra-low floor height of just 21 inches from ground level. In its 3500 High Roof configuration with a 159-inch wheelbase extended cargo box, the 2025 ProMaster delivers a staggering 524 cubic feet of usable interior space. The vertical sidewall design—featuring nearly 90-degree side angles—means aftermarket shelving units, modular bin systems, and sheet goods sit completely flush against the interior walls. A standard 6-foot-4-inch interior standing height ensures technicians, delivery drivers, and tradespeople can comfortably walk upright throughout the entire length of the cargo hold, dramatically reducing fatigue during long workdays. Despite its lightweight unibody shell, the ProMaster 3500 boasts a maximum payload capacity of up to 4,680 lbs. That is more than enough strength to haul heavy pallets of tiles, commercial plumbing fixtures, electrical conduit, or heavy machinery replacement parts. The wide cargo floor provides 56 inches of space between the rear wheel wells, allowing operators to easily load standard 4x8 building sheets or up to three full-sized standard pallets flat on the floor. Loading and unloading is made effortless through dual side-sliding doors with a massive 49-inch opening width and rear clam-shell doors that swing open up to 260 degrees, folding almost flush against the exterior side panels. For local delivery fleets navigating congested loading zones or tight job sites around Junction City and Manhattan, the ProMaster's best-in-class 36-foot turning radius ensures maximum agility. Business owners looking to trade in older delivery vans can complete a fast Trade In Evaluation online to upgrade to the latest 2025 ProMaster lineup. How Do Ram 3500 Diesels Compare to ProMaster Cargo Vans for Heavy Commercial Use? Chassis & Frame Architecture The Ram 3500 utilizes a traditional body-on-frame platform crafted from 50,000 PSI steel. This structural rigidity is built specifically to absorb extreme torsional stress, heavy tongue weights, and severe off-road impacts. By contrast, the Ram ProMaster features an advanced unibody frame that integrates the cab and cargo area into a single steel structure. This cuts overall curb weight, maximizes internal payload capacity, and lowers the center of gravity for improved handling on paved arterial roads. Tongue Weight & Weather Security A Ram 3500 diesel can support vertical tongue weights exceeding 3,500 lbs and gooseneck pin weights over 6,000 lbs, making it the clear winner for open-bed heavy machinery transport. However, open pickup beds leave tools exposed to Kansas weather and theft unless fitted with locking caps. The ProMaster van offers 100% enclosed, lockable weatherproof security, safeguarding thousands of dollars in high-value electrical tools, copper piping, or diagnostic equipment. Upfit Flexibility & Ground Clearance Ram 3500 Chassis Cab models feature standard flat frame rails with C-channel construction, allowing seamless mounting of specialized service bodies, dump beds, bucket lifts, and flatbeds. The ProMaster is optimized for internal modular shelving, walk-through partitions, and mobile workbench configurations. The truck excels in high ground clearance (up to 8.8 inches) and 4x4 off-road mud traction, whereas the van prioritizes low loading heights on paved roads. Selecting the Right Commercial Vehicle for Junction City and Flint Hills Job Sites Commercial fleet demands in central Kansas are uniquely diverse. Operating in Junction City, Fort Riley, and surrounding Geary and Riley counties requires matching vehicle chassis dynamics directly to regional topography and seasonal weather variations. The Flint Hills region is famous for expansive agricultural pastures, rocky unpaved county roads, steep grade changes, and challenging winter conditions where snow and deep mud are constant factors. For agricultural operations, heavy excavation contractors, and utility construction crews operating in unpaved pastures or remote utility easements, a Ram 2500 or 3500 4x4 Diesel is practically indispensable. The mechanical shift-on-the-fly four-wheel-drive transfer case, heavy-duty solid front axle, and available rear limited-slip or electronic locking differentials provide the necessary tractive force to pull loaded livestock trailers or heavy equipment out of slick mud and steep inclines. Furthermore, the Cummins diesel’s standard smart exhaust brake uses variable geometry turbocharger technology to control down-hill speed safely without overheating brake pads. Conversely, for municipal contractors, HVAC service companies, dry-wall installers, and urban delivery routes operating within Junction City, Manhattan, or Salina, the 2025 Ram ProMaster 3500 High Roof provides superior operational efficiency. Its front-wheel-drive system keeps drive components tucked under the cab, providing excellent front tire traction over icy asphalt when the cargo box is loaded. Furthermore, the lower overall vehicle height compared to a lifted 4x4 truck with a high service body simplifies parking inside commercial garages and residential driveways. Operators can easily stop by to visit our dealership or Get Directions to Valor CDJR to test drive both vehicle formats back-to-back. Get Pre-Approved for Commercial Financing Engine Performance and Powertrain Durability Under Continuous Heavy Workloads Commercial durability is measured by how a powertrain performs after hundreds of thousands of miles under maximum thermal and mechanical load. The engineering philosophies driving the Ram HD Cummins Turbo Diesel and the Ram ProMaster Pentastar V6 are tailored to two distinct operational profiles. The 6.7L Cummins Turbo Diesel Inline-Six utilizes a Compacted Graphite Iron (CGI) engine block that delivers superior strength and thermal resistance compared to traditional gray iron. Its inline configuration features fewer moving parts than a V8 diesel engine, simplifying maintenance and extending component lifespan. Cast-iron cylinder heads, forged steel connecting rods, and a high-pressure common-rail fuel injection system operating at up to 29,000 PSI ensure complete fuel atomization and maximum combustion efficiency. Coupled with a heavy-duty cooling system engineered to prevent heat soak under continuous 30,000+ lb towing loads, the Cummins power plant is legendary for achieving 300,000+ mile lifespans in commercial service. The 2025 Ram ProMaster relies on the award-winning 3.6L Pentastar V6 engine paired with a smooth-shifting TorqueFlite 9-speed automatic transmission. Generating 276 horsepower and 250 lb-ft of torque, this naturally aspirated gasoline engine is calibrated specifically for commercial stop-and-go driving cycles. It features variable valve timing (VVT), two-stage variable valve lift, and a high-compression 11.3:1 ratio for exceptional throttle response. The 9-speed transmission keeps the V6 in its optimal powerband, maximizing fuel economy during city delivery routes while maintaining lower engine RPMs during highway cruising. Because the ProMaster uses a gasoline engine, routine maintenance costs are significantly lower—eliminating the need for Diesel Exhaust Fluid (DEF) refills, dual fuel filter maintenance, or specialized low-SAPS diesel oils. Should your fleet require routine servicing, our dedicated Express Lane at Valor CDJR gets your drivers back on the road promptly. Interior Upfit Potential: Modular Van Shelving vs. Heavy Duty Truck Bed Utility ProMaster Modular Shelving For electricians, plumbers, locksmiths, and telecommunication technicians, the ProMaster High Roof is a mobile warehouse. Factory header mounts and interior structural ribs allow turn-key installation of Ranger Design, Adrian Steel, or Knapheide shelving packages. Lockable drawer modules, wire spool racks, drop-down ladder racks, and heavy-duty composite flooring organize thousands of small parts while keeping tools completely dry and locked behind heavy-duty security bulkheads. Ram HD Truck Bed Utility Ram 2500 and 3500 pickup beds offer unique outdoor utility options. The class-exclusive RamBox Cargo Management System provides weatherproof, lockable, drainable side-bed storage bins with LED lighting and 115V power outlets. Heavy-duty sliding bed trays (capable of holding up to 2,000 lbs), auxiliary fuel transfer tanks, cross-bed toolboxes, and headache racks with overhead material supports turn your HD truck into an unbeatable field service platform. Ram Chassis Cab Vocational Bodies For heavy industrial trades, Ram 3500 Chassis Cab models provide an open palette. Featuring standard industry cab-to-axle (CA) dimensions (60 or 84 inches), flat frame rails, and factory auxiliary switch banks, these trucks easily accept specialized service bodies, contractor dump beds, platform flatbeds with hydraulic cranes, or mobile mechanics bodies. Contact our team to explore upfit options using genuine OEM parts through our Parts Department. Total Cost of Ownership, Fuel Efficiency, and Section 179 Tax Benefits for Kansas Businesses Managing fleet finances extends far beyond the initial purchase price. Analyzing Total Cost of Ownership (TCO) requires balancing fuel expenditure, routine preventative maintenance, insurance premiums, equipment depreciation, and available IRS tax incentives. From a fuel economy perspective, the Ram ProMaster 3500's Pentastar V6 gasoline engine delivers excellent city efficiency during multi-stop urban delivery cycles where diesel engines struggle with frequent engine restarts and DPF filter regeneration cycles. Gasoline is generally lower in per-gallon cost than ultra-low sulfur diesel, and routine oil changes use standard synthetic lubricants. For delivery operators logging 15,000 to 25,000 miles per year locally, the ProMaster minimizes operating overhead. However, when hauling heavy loads or pulling trailers over long distances, the 6.7L Cummins Turbo Diesel demonstrates remarkable thermal efficiency. Under heavy load, a diesel engine consumes significantly less fuel per ton-mile than a gasoline engine working at high throttle openings. Furthermore, heavy-duty Ram diesel trucks retain exceptional resale and trade-in value on the secondary market, offsetting their higher initial acquisition cost when it comes time to refresh your fleet. Kansas business owners can also take advantage of substantial tax savings through IRS Section 179 and Bonus Depreciation rules. Because both the Ram 2500/3500 series and the Ram ProMaster 3500 feature Gross Vehicle Weight Ratings (GVWR) exceeding 6,000 lbs, qualifying businesses may write off up to 100% of the purchase price during the first year of tax service, subject to current federal IRS guidelines. This immediate tax deduction reduces net cash outflow significantly, allowing local business owners in Junction City to reinvest capital into new tools, equipment, or business expansion.

Is the RAM 4500 Chassis Cab the Right Work Truck for Kansas Contractors? The Ram 4500 Chassis Cab is an ideal work truck for Kansas contractors who require commercial payload and towing strength without forcing drivers into a Commercial Driver's License. Rated up to 16,500 pounds Gross Vehicle Weight Rating, it allows standard Class C licensed crew members to operate a heavy-duty platform. Combined with high-strength C-channel frame rails and up to 28,550 pounds of diesel towing capacity, it delivers vocational muscle for demanding job sites. For commercial operations in Central Kansas, licensing efficiency directly impacts daily labor scheduling and payroll costs. Because federal regulations set the single-vehicle Commercial Driver's License threshold at 26,001 pounds Gross Vehicle Weight Rating (GVWR), a standalone Ram 4500 Chassis Cab sits comfortably beneath that legal boundary. Fleet owners can assign non-CDL drivers to transport heavy loads, operate auxiliary equipment, and maneuver essential vocational bodies without paying specialized CDL wages or managing complex commercial driver compliance tracking. However, business owners must account for total combination weight when pulling trailing equipment. Under Federal Motor Carrier Safety Administration guidelines, a Class A CDL becomes mandatory if the combined rating of the truck and trailer exceeds 26,001 pounds Gross Combined Weight Rating (GCWR) and the trailer itself carries a manufacturer GVWR tag over 10,000 pounds. For example, pairing a 16,500-pound GVWR Ram 4500 with a 12,000-pound equipment trailer yields a combined rating of 28,500 pounds, requiring a CDL operator. Matching the truck with a trailer rated at or under 9,500 pounds keeps total GCWR at or below 26,000 pounds, preserving non-CDL status for everyday operations. Selecting the right chassis configuration ensures your business maximizes job site capability while maintaining full regulatory compliance. To discuss chassis configurations and examine available models, stop by our Junction City showroom location or connect directly with our commercial specialists by calling our sales team at (785) 238-5114.

What Cab, Frame, and Dual Alternator Upfits Work Best for Junction City Contractors? How Does the Ram 4500 Compare to the Ford F-450 Super Duty Chassis Cab? What Commercial Financing and BusinessLink Options Help Contractors Buy at Valor CDJR? Common Questions About the Ram 4500 Chassis Cab Upgrade Your Commercial Fleet with the Ram 4500 at Valor CDJR What Engine Options and Towing Capabilities Power the Ram 4500 Chassis Cab? The Ram 4500 Chassis Cab offers two commercial powertrains: a standard 6.4-liter HEMI V8 gas engine generating 370 horsepower and 429 lb-ft of torque, and an available 6.7-liter Cummins turbo-diesel inline-six delivering 360 horsepower and 800 lb-ft of torque. Both engines are paired with heavy-duty commercial transmissions engineered to sustain severe-duty work cycles under heavy loads. The 6.4-liter HEMI V8 gas engine utilizes variable cam timing and fuel-saving cylinder deactivation to deliver responsive performance for regional service tasks. Paired with a commercial automatic transmission, the gas configuration supports a Gross Combined Weight Rating of 28,500 pounds and enables conventional and gooseneck towing capacities up to 21,240 pounds. Because gas engines weigh less than heavy iron-block diesels, choosing the HEMI V8 maximizes available chassis payload capacity for heavy mounted bodies like service cranes or concrete mixers. For extreme towing applications, the 6.7-liter Cummins turbo-diesel inline-six provides low-end pulling power essential for heavy equipment transportation. Mated exclusively to the heavy-duty AISIN six-speed automatic transmission, the Cummins diesel generates its peak 800 lb-ft of torque low in the RPM band. This low-end torque makes pulling heavy skid-steers, MINI-excavators, and multi-ton material trailers up steep, unpaved inclines simple and controlled. When properly configured with a gooseneck hitch, a diesel-powered Ram 4500 4x4 delivers a maximum towing rating up to 28,550 pounds with a maximum GCWR of 37,500 pounds. Heavy-duty commercial stopping power is maintained by oversized 15.4-inch front brake rotors paired with twin-piston calipers. On diesel models, an integrated smart exhaust brake provides supplemental retarding force down rolling hills around Manhattan, reducing wear on brake pads and maintaining thermal stability during heavy descents. Business owners seeking reliable work vehicles can explore our current pre-owned commercial truck inventory to compare high-capability pre-owned options. What Are the Maximum Payload Capacity and GVWR Ratings for the Ram 4500? The Ram 4500 Chassis Cab delivers a maximum Gross Vehicle Weight Rating of 16,500 pounds, yielding maximum payload capacities up to 9,390 pounds with the gas engine and up to 8,560 pounds with the Cummins turbo-diesel. Net payload is calculated by subtracting the unladen curb weight of the bare chassis and cab from the total factory GVWR. Achieving high payload ratings requires a severe-duty structural foundation. The Ram 4500 is constructed with flat, high-strength 50,000-PSI steel C-channel rear frame rails utilizing industry-standard 34-inch spacing. Unlike curved pickup frames, this flat structural layout provides a clean mounting plane that accepts aftermarket bodies without requiring custom frame brackets or structural alterations. Key chassis component ratings supporting severe-duty payloads include: Heavy-duty front axle rated up to 7,000 pounds Gross Axle Weight Rating (GAWR) for supporting heavy front-mounted equipment or snowplows Commercial rear axle assembly supporting up to 12,000 pounds rear GAWR to absorb vertical pin weights from gooseneck trailers Commercial-grade 15.4-inch disc brake assemblies engineered for repeatable thermal heat dissipation under continuous gross weight conditions Dual rear wheel axle configurations with heavy-duty multi-leaf rear suspension assemblies designed to prevent rear-end squat under capacity loads Whether mounting a steel dump body loaded with aggregate or installing a fully equipped service utility body with heavy onboard tool storage, the Class 4 frame handles structural loads with minimal flex.

In Kansas, drivers can operate the Ram 4500 Chassis Cab commercially without needing a Commercial Driver's License, simplifying fleet management. With a Gross Vehicle Weight Rating between 14,000 pounds and 16,500 pounds, the truck sits below the 26,001-pound single-vehicle CDL mandate threshold. Any employee holding a valid Class C driver's license can operate the truck itself. However, if the truck pulls a trailer with a GVWR over 10,000 pounds and the total combined weight rating exceeds 26,001 pounds, a Class A CDL is legally required for that driver. Q: Does the Ram 4500 offer a dual alternator option for heavy electrical tools? The Ram 4500 Chassis Cab offers an available dual alternator system delivering a combined maximum output of 440 amps. Utilizing two 220-amp alternators, this setup provides consistent electrical current for high-draw onboard systems, power inverters, exterior job site lighting arrays, and electric-over-hydraulic lift equipment without overtaxing the vehicle's primary starting battery. Q: What cab-to-axle lengths are available on the Ram 4500 Chassis Cab? The Ram 4500 Chassis Cab is manufactured in four distinct Cab-to-Axle (CA) lengths: 60-inch, 84-inch, 108-inch, and 120-inch spacing. These dimensional options allow contractors and body builders to mount utility beds, dump bodies, platform flatbeds, and mechanic crane bodies ranging from 9 feet to 16 feet in length while maintaining balanced axle loading. Q: Can the Ram 4500 power hydraulic upfits while the truck is moving? The Ram 4500 Power Take-Off ( PTO) system integrated with the AISIN six-speed automatic transmission supports mobile and stationary operating modes. Stationary mode powers stationary equipment like dump beds, bucket booms, and cranes while parked. Mobile mode supplies mechanical or hydraulic power to accessories like salt spreaders or street sweepers while the vehicle remains in motion. Q: How does the Ram 4500 qualify for commercial Section 179 tax benefits? Because the Ram 4500 Chassis Cab has a Gross Vehicle Weight Rating exceeding 6,000 pounds, it meets federal criteria for Section 179 tax treatment. Eligible commercial businesses may write off up to 100% of the vehicle's purchase cost in the year it is placed into service rather than depreciating the asset over multiple years. Business owners should consult their financial advisor or tax preparer for specific application details.

What Cab Configurations and Frame Lengths Are Offered on the Ram 4500? When configuring a commercial workhorse like the 2025 Ram 4500 Chassis Cab, matching your cab selection and frame dimensions precisely to your operational needs is the single most critical decision you will make. The Ram 4500 is engineered from the ground up to accommodate a vast range of commercial applications across Kansas, from heavy-duty ag operations in Geary County to municipal utility crews in Manhattan and construction sites in Junction City. Understanding how cab style and Cab-to-Axle (CA) measurements interact with body length, payload distribution, and overall turning geometry is essential before committing capital to a commercial fleet addition. The Ram 4500 Chassis Cab is manufactured in two primary cab configurations: the Regular Cab (2-door, 3-passenger capacity) and the Crew Cab (4-door, 5-to-6 passenger capacity). The Regular Cab layout maximizes available frame space behind the rear window, offering four distinct Cab-to-Axle (CA) frame lengths: 60 inches (144.5-inch wheelbase), 84 inches (168.5-inch wheelbase), 108 inches (192.5-inch wheelbase), and 120 inches (204.5-inch wheelbase). In contrast, the spacious Crew Cab configuration is paired with two primary frame lengths: 60 inches CA (173.5-inch wheelbase) and 84 inches CA (197.5-inch wheelbase). Every frame length features standardized 34-inch wide, steel rear frame rails with flat top surfaces and through-the-frame rivet construction, allowing upfitters to mount bodies without needing complex adapter brackets or structural modifications. Ram 4500 Configuration & Upfit Compatibility Summary Matrix Cab Type Cab-to-Axle (CA) Wheelbase Recommended Body Length Primary Upfit Applications Regular Cab 60 inches 144.5 inches 9 ft – 10 ft Short Service Body, MINI-Dump, Tight-Space Utility Regular Cab 84 inches 168.5 inches 11 ft – 12 ft Medium Service Body, Contractor Flatbed, Farm Hauler Regular Cab 108 inches 192.5 inches 14 ft Long Flatbed, Grain Body, Heavy Haul Stake Bed Regular Cab 120 inches 204.5 inches 16 ft – 18 ft Extended Flatbed, Rollback Tow Bed, Large Dry Freight Crew Cab 60 inches 173.5 inches 9 ft – 10 ft Crew Service Body, Utility Maintenance, Mobile Workshop Crew Cab 84 inches 197.5 inches 11 ft – 12 ft Crew Flatbed, Agricultural Transport, Municipal Crew Dump Choosing the correct CA dimension dictates not only what size body you can physically bolt to the frame rails, but also how front-to-rear axle weight distribution behaves under full load. Selecting too short of a CA for a long flatbed causes excessive overhang behind the rear axle, taking weight off the front tires, degrading steering feel, and accelerating tire wear. Conversely, selecting an unnecessarily long frame increases your curb weight, expands your turning circle, and reduces payload headroom.

Meet Mike Hogg: 20 Years of Commercial Truck Service Insights in Geary and Riley Counties Hello, I am Mike Hogg, Service Director here at Valor CDJR. Over my two decades managing heavy-duty commercial service operations in Junction City, I have worked hand-in-hand with hundreds of Kansas general contractors, cattle ranchers, grain farmers, and municipal utility managers across Geary, Riley, and Dickinson counties. I have seen firsthand what happens when a medium-duty chassis truck is properly specced from day one—and the costly head-aches that occur when a fleet operator buys the wrong frame length or cab setup for their operational reality. My philosophy on medium-duty chassis specification is straightforward: 'Build the truck for the payload and jobsite access requirements of year five, not just day one.' Kansas working environments demand exceptional frame rigidity, predictable handling under heavy tongue-weight trailers, and rugged PTO integration. Whether you are navigating rutted field roads along the Smoky Hill River or maneuvering into tight commercial jobsites in downtown Manhattan, getting your cab configuration and frame specs right guarantees maximum uptime and long-term resale value. If you ever have technical questions about PTO pump clearance, auxiliary harness routing, or rear axle load calculations, reach out directly to our specialized service department.

Matching Ram 4500 Cab-to-Axle Dimensions to Flatbed, Dump Body, and Service Upfits Understanding the functional connection between Cab-to-Axle (CA) length and body design is fundamental. CA is defined as the distance in inches from the back of the vehicle cab to the centerline of the rear axle. Upfit manufacturers design standard body lengths—such as 9-foot, 11-foot, 14-foot, and 16-foot bodies—specifically to align with standardized industry CA dimensions. Here is how each Ram 4500 frame offering performs in real-world Kansas trades: 1. The 60-Inch CA (Regular Cab & Crew Cab): Ideal for 9-foot to 10-foot utility service bodies, compact dump bodies, and short flatbeds. The 60-inch CA Regular Cab features a tight 144.5-inch wheelbase, making it highly maneuverable in residential neighborhoods, municipal alleyways, and congested construction zones. In Crew Cab form, the 60-inch CA accommodates a 4-man work crew while retaining a compact overall footprint for towing utility trailers. 2. The 84-Inch CA (Regular Cab & Crew Cab): The true multi-purpose workhorse of the Midwest. An 84-inch CA perfectly accepts 11-foot to 12-foot contractor flatbeds, crane service bodies, and heavy agricultural drop-side beds. It provides exceptional balance, leaving ample room behind the cab for hydraulic oil tanks, fuel transfer tanks, or behind-cab toolboxes without crowding the rear axle load centerline. 3. The 108-Inch CA (Regular Cab Only): Engineered for 14-foot body installations, this setup is widely favored by fencing contractors, farm suppliers, and bulk material distributors. The extra length allows for high-cube utility bodies or high-capacity flatbeds designed to transport palleted seed, fencing materials, or livestock feed around rural Kansas. 4. The 120-Inch CA (Regular Cab Only): The longest factory chassis cab offered in the Ram 4500 lineup, featuring a 204.5-inch wheelbase. Designed specifically for 16-foot to 18-foot flatbeds, car hauler rollback beds, and dry freight box bodies. It delivers maximum platform square footage for commercial haulers while maintaining strict factory GVWR ratings. Upfitter Note from Mike Hogg: 'When selecting an upfit, never forget to calculate rear frame overhang. A common mistake is mounting a 12-foot bed on a 60-inch CA frame. That creates over 5 feet of tail swing behind the axle. Every pound placed at the rear gate acts like a lever, lifting weight off your steering axle and compromising control during rain or snow on Highway 77.'

Browse Commercial Vehicle Inventory How Much Extra Does the 6.7L Cummins Diesel Engine Option Cost on a Ram 4500? Selecting the powertrain for your Ram 4500 represents one of the largest single financial line items during spec configuration. The Ram 4500 comes standard with the heavy-duty 6.4L HEMI® V8 Heavy-Duty Gasoline Engine paired with an AISIN 6-speed automatic transmission. Opting for the available commercial-grade 6.7L Cummins® Turbo Diesel I6 Engine for current pricing, contact the dealership (depending on production trim and optional equipment packages). While $10,000 represents a significant initial capital investment, evaluating this decision through a total-cost-of-ownership (TCO) lens reveals why many Kansas commercial buyers elect the Cummins diesel powertrain: Torque Under Heavy Towing: The 6.7L Cummins Diesel delivers up to 800 lb-ft of torque at low RPM (1,600 RPM), enabling effortless pull when launching heavy equipment trailers from muddy field gates or steep grades. The 6.4L HEMI V8 produces 429 lb-ft of torque at 4,000 RPM, requiring higher engine speeds to maintain momentum under load. Fuel Efficiency Under Continuous Payload: When operating continuously near maximum Gross Combined Weight Ratings (GCWR), diesel combustion efficiency yields significantly lower fuel consumption per operating hour, offsetting up to 40% of the initial option cost over a 150,000-mile commercial service lifespan. Commercial Engine Brakes & PTO: The Cummins diesel includes a fully integrated exhaust brake with manual and auto modes, reducing friction brake wear during steep hill descents. Furthermore, the left-side or right-side Power Take-Off (PTO) capability provides robust mechanical power for hydraulic pumps. Resale Value Retention: In the commercial resale market throughout Kansas and Nebraska, diesel chassis cabs command a premium over gasoline chassis units, often recovering $5,000 to $7,000 of the original option cost at trade-in time.

What Tire and Wheel Setup Does the Ram 4500 Use Compared to the Ram 3500? A frequent point of confusion among fleet managers step-up from Class 3 (Ram 3500) to Class 4 (Ram 4500) trucks is the running gear. While the Ram 3500 Dual Rear Wheel (DRW) utilizes consumer light-truck running gear, the Ram 4500 transitions entirely into medium-duty commercial hardware built for extreme duty cycles. 19.5-Inch Wheel Hardware The Ram 4500 features heavy commercial 19.5 x 6.0-inch steel or forged aluminum wheels, compared to the 17-inch wheels standard on Ram 3500 DRW. Standard tire fitment is 225/70R19.5G commercial highway or traction tires, featuring substantially thicker sidewalls and higher load range G ratings. 10-Lug Heavy Duty Hub Pattern While the Ram 3500 uses an 8-lug wheel bolt pattern, the Ram 4500 employs a robust 10-lug on 225mm bolt circle heavy commercial hub pattern. This massive hub assembly distributes wheel clamping forces far more effectively under severe cornering loads and heavy payload distribution. Brake Thermal Management The 19.5-inch wheel diameter creates extra internal clearance required to house massive 15.35-inch front rotors and heavy-duty dual-piston calipers. Larger commercial wheel cavities allow far greater air circulation, preventing heat soak during repeated high-payload downhill braking events. Expert Perspective: Why Frame Rigidity and CA Sizing Drive Real-World Payload Profits 'In commercial truck service, frame flex is the silent killer of bodies and drivelines,' explains Mike Hogg. 'The Ram 4500 uses high-strength 50,000 PSI steel frame rails with full C-channel rear crossmembers. When you mount a heavy dump body or a 14-foot crane service body, that structural rigidity prevents frame twist when operating on uneven ranch terrain or unpaved job sites.' When a frame twists excessively under maximum load, it places torsional stress on the transmission output shaft, driveshaft U-joints, and rear differential bearings. By maintaining a flat 34-inch wide frame rail standard with zero top-rail rivets, Ram allows upfitters to mount bodies directly to high-tensile steel frame webs. This clean mounting design eliminates flex points, protects sensitive hydraulic lines, and keeps your truck out of the repair bay. Need replacement parts or specialized mounting brackets?

The 2025 Ram 4500 Chassis Cab is engineered to deliver class-leading weight ratings across both Regular Cab and Crew Cab configurations: Gross Vehicle Weight Rating (GVWR): Up to 16,500 lbs. Maximum Payload Capacity: Up to 12,080 lbs (varies based on cab style, CA length, drivetrain, and upfit body weight). Maximum Towing Capacity: Up to 29,770 lbs when equipped with the 6.7L Cummins Turbo Diesel and factory max-tow package. Gross Combined Weight Rating (GCWR): Up to 37,500 lbs. These ratings make the Ram 4500 an appropriate choice for towing heavy equipment trailers, backhoes, and multi-car haulers across Geary and Riley counties without crossing into Class 6 Commercial Driver License (CDL) requirements in many standard agricultural operations. Ram 4500 Ratings by Drivetrain & Configuration Engine Max GVWR Max Payload Max Towing Max GCWR 6.4L HEMI V8 Gas 16,500 lbs 12,080 lbs 21,500 lbs 28,500 lbs 6.7L Cummins Diesel 16,500 lbs 11,250 lbs 29,770 lbs 37,500 lbs Get Pre-Approved For Commercial Financing How Do Turning Radius Capability Figures Compare Between Ram 4500 and Ford F-450? On crowded jobsites and narrow farm driveways throughout Geary County, maneuverability is just as important as raw horsepower. Ram engineers addressed this challenge by designing a dedicated wide-track front axle setup with link-coil front suspension, permitting up to a 52-degree wheel-cut angle. When compared directly to the Ford F-450 Chassis Cab, the Ram 4500 delivers remarkable tight-space turning diameter performance: Ram 4500 Regular Cab (60-inch CA / 144.5" WB): Turning curb-to-curb diameter of approximately 42.1 feet. Ford F-450 Regular Cab (60-inch CA / 145.3" WB): Turning curb-to-curb diameter of approximately 43.5 feet. Ram 4500 Crew Cab (60-inch CA / 173.5" WB): Turning curb-to-curb diameter of approximately 49.8 feet. That tighter turning radius allows drivers to navigate tight barns, maneuver around grain augers, and parallel park service bodies on downtown streets with significantly fewer multi-point turns. What Should Kansas Farm and Contracting Buyers Verify Before Choosing a Service, Flatbed, or Dump-Body Upfit? To eliminate costly rework or delays when partnering with body builders, run through this pre-purchase verification checklist with our commercial sales specialists: 1. Alternator & Electrical Outlets Verify if your upfit requires dual alternators (up to 440 amps combined output) to charge auxiliary jobsite batteries, power electric-hydraulic hoists, or drive high-draw LED lightbars. 2. Power Take-Off (PTO) Left/Right Routing Confirm whether your hydraulic pump mounts on the left or right side of the AISIN transmission. Ram 4500 provides dual-side PTO access capabilities to clear exhaust piping. 3. VSIM Module Interfacing Ensure your vehicle is specced with the factory Vehicle System Interface Module (VSIM). It provides 70+ electrical circuits for seamless aftermarket body integration. Do Kansas Agricultural Operations Qualify for Sales Tax Exemptions on Commercial Chassis Trucks? Yes! Under Kansas Department of Revenue tax statutes, vehicles, machinery, and equipment purchased for direct and exclusive use in agricultural production can qualify for state sales tax exemptions. In Riley and Geary counties, qualifying farmers and ranchers utilizing a Ram 4500 for farming, livestock movement, or agricultural material transport can save thousands of dollars at purchase when proper documentation is completed. Key requirements to keep in mind: Kansas Agricultural Exemption Certificate (Form ST-28A): Must be completed and kept on file at the dealership during the purchasing transaction. Qualifying Use Cases: Transporting agricultural products, feeding livestock, spraying crops, or hauling machinery between agricultural parcels. Commercial Line of Credit: Combining tax-exempt status with commercial fleet financing or specialized commercial leases maximizes capital efficiency for expanding agricultural businesses. Evaluate Your Trade-In Online Commercial Chassis Cab Overview: Ram 4500 Capability for Kansas Farms and Contractors Operating a commercial truck like the Ram 4500 requires a rigorous, proactive maintenance strategy.
