Maximizing RAM 4500 Capability for Kansas Workloads: Expert Q&A with Dustin Zeck The 2027 Ram 4500 Chassis Cab offers two distinct powertrains: a standard 6.4-liter HEMI V8 gas engine delivering 375 horsepower and 429 lb-ft of torque, and an available 6.7-liter Cummins turbo-diesel inline-six producing 360 horsepower and 800 lb-ft of torque, with both engines paired with an eight-speed TorqueFlite HD automatic transmission. To help commercial buyers and equipment operators make informed vehicle investments, we sat down with Dustin Zeck, Dealer Principal at Valor CDJR, who brings 36 years of commercial truck experience to walk us through configuring these trucks for demanding regional work. Q: What engine options are available on the Ram 4500 Chassis Cab? A: For 2027, Ram has announced two high-capability powertrains on the Ram 4500 Chassis Cab lineup to match varying commercial requirements. The baseline commercial engine is the 6.4-liter HEMI V8 gas motor, which generates 375 horsepower and 429 lb-ft of torque. This engine relies on Variable Cam Timing and Fuel Saver Technology to balance output with fuel management during stop-and-go work routines. When maximum towing capability is required, buyers can step up to the 6.7-liter Cummins turbo-diesel inline-six, which delivers 360 horsepower and 800 lb-ft of low-end torque. Both engines send power through the eight-speed TorqueFlite HD automatic transmission, engineered specifically to withstand heavy commercial duty cycles while delivering precise electronic column shifting. Choosing between the two powertrains depends heavily on daily mileage and trailer weight. Commercial fleets that handle localized utility tasks or lighter equipment bodies usually find the 6.4-liter HEMI V8 to be a cost-effective option, offering a maximum gas payload rating of up to 9,390 pounds and a maximum tow rating of 21,240 pounds. On the other hand, contractors pulling heavy machinery or livestock goosenecks continuously benefit from the Cummins diesel engine, which bumps maximum diesel towing up to 29,440 pounds and maximum Gross Combined Weight Rating to 37,500 pounds. If you are planning to add a chassis cab truck to your fleet, our sales specialists at our dealership location on Goldenbelt Boulevard can help you evaluate expected payloads and trailering requirements. You can also reach out directly to our commercial truck team by giving us a call at (785) 238-5114 to discuss custom ordering, cab-to-axle options, and current commercial incentives. Q: How does the Ram 4500 compare to the Ford F-450 Super Duty Chassis Cab? A: The Ram 4500 Chassis Cab distinguishes itself from the Ford F-450 primarily through its upfitter-friendly architecture and frame engineering. Ram equips the 4500 chassis with standard 50,000 PSI steel frame rails featuring flat frame tops and clean rear frame sections, which simplifies mounting custom bodies, flatbeds, or utility service bodies without demanding extensive structural modifications. While the Ford F-450 utilizes an aluminum body construction and offers higher peak diesel horsepower ratings on paper, the Ram 4500 focuses on structural rigidity, higher available rear axle weight ratings, and straightforward upfit integration that reduces labor costs at the body builder stage. Another crucial operational factor is powertrain refinement and power delivery under heavy loads. The TorqueFlite HD automatic transmission in the Ram 4500 works in tandem with an available class-exclusive active air grille shutter system that adjusts continuously based on engine load and temperature, ensuring optimal cooling during long pulls on summer days. Furthermore, Ram offers an available electronic front axle disconnect on 4x4 models, which automatically disengages the front axle when four-wheel drive is not engaged, helping trim unnecessary driveline drag during long highway runs. Business owners evaluating heavy-duty chassis options can explore our latest new vehicle inventory to compare cab styles, drivetrain layouts, and cab-to-axle lengths across our heavy-duty truck selection. Q: Does the Ram 4500 offer Power Take-Off (PTO) capability and high alternator output for upfits? A: Yes, the Ram 4500 Chassis Cab provides comprehensive Power Take-Off capability designed specifically to run hydraulic pumps, dump beds, lift buckets, and generator systems. Ram engineered the transmission housing to accommodate PTO access from both the left and right sides on 4x2 and 4x4 configurations. When paired with the 6.7-liter Cummins turbo-diesel inline-six, the system includes a split-shaft mode that allows operators to choose between two operating speeds, even while the vehicle is stationary, offering precise throttle response for demanding vocational tools. "Having split-shaft PTO capability on both sides of the transmission gives commercial fleets complete flexibility when mounting hydraulic pumps and specialized equipment." To support power-hungry electrical equipment, light bars, and hydraulic controls, the Ram 4500 can be ordered with dual alternators generating up to 440 amps of total electrical output. This high-capacity charging setup ensures consistent voltage supply without draining the battery or overheating auxiliary circuits, even during prolonged idling on remote job sites. Commercial operators interested in pre-owned commercial platforms can review our pre-owned commercial inventory to see work-ready chassis cabs fitted with various upfits. Q: What rear axle ratios and GCWR ratings are best for heavy towing across Kansas? A: To achieve maximum towing capability and maintain strong pull off the line, specifying a 4.44 rear axle ratio or a 4.89 rear axle ratio is often appropriate. These numerical ratios supply the low-end mechanical advantage needed to start heavy gooseneck and equipment trailers on steep inclines or soft dirt. When properly equipped with the Cummins diesel and a heavy-duty axle package, the Ram 4500 reaches a Gross Combined Weight Rating of 37,500 pounds and a maximum trailer tow capacity of 29,440 pounds, provided the load is hitched via an approved gooseneck or fifth-wheel system mounted directly to the frame. When pulling heavy machinery across the rolling Flint Hills terrain near Manhattan, having the proper axle gearing prevents the transmission from hunting between gears and keeps engine temperatures within optimal operating windows. When fleets consult with our commercial sales team, we carefully cross-reference trailer weights and cargo styles against factory axle ratios to ensure the vehicle remains well within its legal Gross Vehicle Weight Rating and Gross Combined Weight Rating envelopes. To help offset the initial purchase cost of upgrading your fleet chassis, business owners can evaluate your trade-in online to value your trade-in toward a new commercial acquisition. Q: Why choose a Ram 4500 over a Ram 5500 for farm work around Junction City? A: The primary advantage of choosing a Ram 4500 over a Class 5 Ram 5500 for agricultural use comes down to driver licensing flexibility and operating efficiency. The Ram 4500 provides exceptional capability with up to 9,390 pounds of gas payload and 28,500 pounds of gas GCWR, or 37,500 pounds of diesel GCWR, while allowing farm managers to keep total combined vehicle weight ratings under the 26,000-pound threshold when pulling moderate farm trailers. Staying under that regulatory line means non-CDL drivers, seasonal farm hands, and family members can legally operate the truck without requiring a Commercial Driver License. For agricultural operations supporting surrounding fertile farm acreage around Junction City, the Ram 4500 offers the practical middle ground between a standard 3500 pickup and a massive Class 5 commercial rig. It delivers the heavy-duty frame strength, dual rear wheels, and high-output alternator power necessary for pulling stock trailers or carrying large hay flatbeds without the stiffer ride quality, higher registration fees, and strict CDL oversight often associated with heavier Class 5 platforms. Farm managers and local business owners looking to add specialized workhorses to their fleet can browse our selection of new commercial vehicles to find chassis cabs ready for flatbed or stake-body installation. Q: How can Section 179 tax deductions and commercial financing discuss your business investment? A: Because the Ram 4500 Chassis Cab features a Gross Vehicle Weight Rating well above 6,000 pounds, qualifying business owners who purchase the truck for commercial use can leverage IRS Section 179 vehicle expense tax deductions. Under Section 179 rules, eligible businesses may deduct up to 100 percent of the purchase cost of qualified heavy commercial vehicles in the tax year the vehicle is placed into service, rather than depreciating the asset slowly over several years. This substantial tax benefit directly reduces net acquisition costs and allows fleet managers to reinvest capital back into specialized upfits, tools, and business expansion. Navigating commercial purchasing options is straightforward when working with experienced truck specialists. Whether you are adding a single service truck or updating an entire fleet, our team can guide you through commercial financing information and tax-related documentation. To start your commercial truck purchase, you can get pre-approved for commercial financing online before scheduling your showroom visit.

Maximizing RAM 4500 Capability for Kansas Workloads Does Operating a Ram 4500 at 16,500 lbs GVWR Require a CDL in Kansas? Operating a standalone truck with a 16,500-pound GVWR does not require a Commercial Driver's License (CDL) in Kansas when carrying standard commercial goods or tools. Under Kansas Department of Revenue Division of Vehicles rules, a CDL is only triggered when a single vehicle has a gross vehicle weight rating of 26,001 pounds or more, or when pulling a trailer with a GVWR over 10,000 pounds pushes the combined rating past 26,001 pounds. This licensing threshold makes Class 4 chassis cabs one of the most versatile investments for growing operations. When I walk commercial managers through fleet acquisitions, CDL compliance is often their top operational concern. Standard drivers can legally operate a Ram 4500 daily without requiring specialized commercial licensing endorsements, which eliminates a major hiring hurdle for local crews. However, combined weight calculations require careful monitoring once you hitch a heavy trailer behind the chassis. If your Ram 4500 carries a 16,500-pound GVWR and pulls a tandem-axle equipment trailer rated at 12,000 pounds, your total gross combination weight rating reaches 28,500 pounds. Because the combination rating surpasses 26,001 pounds and the trailer exceeds 10,000 pounds, the driver must hold a Class A CDL. If you hook up a lighter utility trailer rated at 9,500 pounds, the combination remains CDL-exempt because the trailer itself stays under the 10,000-pound cutoff, even though the total gross combination weight rating reaches 26,000 pounds. Keeping your drivers compliant while maximizing vehicle utility comes down to choosing the right chassis configuration from the start. If your daily routes do not require maximum frame loading, Ram offers factory de-rated packages with a 16,000-pound or 15,000-pound GVWR. If you want to review truck specs or plan a custom chassis layout, visit our Junction City showroom at 1825 Goldenbelt Blvd or give our team a direct call to discuss commercial configurations.

What Business Incentives and Fleet Programs Does Ram Offer Commercial Buyers? How Can You Configure and Secure the Right Ram 4500 Chassis Cab? What Are the Ram 4500 Maximum Towing, Payload, and Combined-Weight Ratings? The Ram 4500 Chassis Cab delivers a maximum towing capacity of up to 29,440 pounds, a maximum payload capacity of 8,560 pounds, and a maximum 37,500-pound GCWR when equipped with the 6.7L Cummins Turbo Diesel engine. Gas-powered models driven by the 6.4L HEMI V8 deliver a maximum towing capacity of 21,240 pounds, a maximum payload capacity of 9,390 pounds, and a 28,500-pound GCWR. Choosing between gas and diesel powertrains depends on whether your workload prioritizes ultimate trailer pulling or maximum frame-mounted payload. The 6.4L HEMI V8 produces 375 horsepower and 429 lb-ft of torque, backed by a TorqueFlite HD eight-speed automatic transmission. Because the gas engine weighs less than a cast-iron diesel block, it frees up net carrying capacity on the front and rear axles, allowing upfitters to mount heavier service bodies, dump beds, or utility cranes without exceeding the vehicle's 16,500-pound GVWR. For heavy-duty trailering across rolling Flint Hills routes around Manhattan, the 6.7L Cummins Turbo Diesel is the heavy-duty benchmark. Generating 360 horsepower and 800 lb-ft of torque, this inline-six engine pairs with an eight-speed automatic transmission featuring an electronic column shifter. The diesel engine uses robust heavy-duty pistons, a revised turbocharger, and high-pressure fuel injection to sustain high torque at low engine speeds. To hit maximum towing limits, your rig must use a properly rated fifth-wheel or gooseneck hitch system anchored directly to the frame. Standard rear receiver hitches are capped at lower weight limits, making frame-integrated mounting hardware mandatory for hauling heavy machinery. If you are comparing pre-owned commercial platforms or trade-ins, browsing our pre-owned commercial lineup helps you evaluate pre-equipped towing packages. How Do the Ram 3500 HD and Ram 4500 Chassis Cab Differ for Heavy Duty Work? Ram 3500 HD pickups and Ram 4500 Chassis Cabs differ notably in frame strength, axle capacity, and gross vehicle weight ratings, impacting their suitability for heavy-duty tasks. The Ram 3500 HD is a Class 3 vehicle capped at a 14,000-pound GVWR with a boxed frame and a factory pickup box, whereas the Ram 4500 is a true Class 4 commercial chassis cab featuring a 16,500-pound GVWR and flat, C-channel frame rails. Pickup truck frames use curved rear rails designed for ride comfort and factory bed mounting, which makes installing custom vocational bodies difficult. The Ram 4500 utilizes industry-standard 50,000-PSI steel C-channel frame rails that are completely flat behind the cab. With no components or hydraulic lines protruding above the top flange, body builders can bolt service bodies, flatbeds, or box bodies straight to the frame without custom spacer brackets. Axle construction and track width also separate these two platforms. The Ram 4500 uses heavier forged front beam axles and massive rear dual-wheel axles with larger brake rotors, heavy-duty wheel bearings, and commercial 19.5-inch wheels. These commercial components provide higher front gross axle weight ratings and greater stability under top-heavy payloads, such as bucket lifts or high-volume grain boxes. Transmission gearing and Power Take-Off (PTO) capabilities further reflect the Ram 4500’s work-first design. The Ram 4500 offers left- and right-side PTO access with split-shaft capabilities on the transmission, enabling operators to power hydraulic pumps, generators, or winches directly from the engine. If you are considering transitioning your fleet from Class 3 pickups to dedicated chassis cabs, you can evaluate your trade-in online to see how your current trucks fit into an upgrade plan. Which Cab-to-Axle Lengths and Frame Options Support Junction City Body Upfits? The Ram 4500 Chassis Cab comes in four industry-standard cab-to-axle (CA) lengths—60-inch, 84-inch, 108-inch, and 120-inch—available across Regular Cab and Crew Cab body styles to accommodate diverse vocational bodies. Matching the correct CA length to your specific upfit ensures proper weight distribution over the front and rear axles while keeping the vehicle maneuverable on Jobsite grounds. For local contractors and municipal crews operating near Fort Riley in Junction City, selecting the right frame layout is essential for daily efficiency. A 60-inch CA Regular Cab or Crew Cab is the preferred setup for 9-foot to 11-foot utility service beds, dump bodies, and mechanic cranes, delivering a tight turning radius for navigating crowded work yards. The longer 84-inch, 108-inch, and 120-inch CA Regular Cab configurations support 12-foot to 20-foot stake beds, rollback car haulers, and oversized aluminum box bodies. Ram engineers built the chassis cab with upfitter-friendly wiring and plumbing routing to simplify body installation. Through-the-frame electrical harnesses and fuel lines prevent wire pinching between the upfit body and the frame rails. A rear-mounted Diesel Exhaust Fluid (DEF) filler port located on the driver’s side cab pillar allows easy fluid top-offs without opening the upfit doors or reaching under custom beds. An available onboard power inverter delivers up to 2.4 kilowatts of electrical power with a relocatable point of service for operating power tools directly on job sites. The optional Heavy Duty Snow Plow Prep Group equips the front suspension with heavy-duty springs and a high-output alternator setup to handle heavy plow blades during Kansas winter storms. Dual-alternator configurations providing up to 480 amps are available for high-draw equipment, such as emergency lighting packages, hydraulic lift gates, or auxiliary refrigeration units. These factory-installed electrical choices reduce labor costs at the upfitter shop and protect the vehicle's primary electrical system under heavy loads. How Much Does the 6.7L Cummins Diesel Engine Add to Your Upfront Purchase Price? Selecting the 6.7L Cummins Turbo Diesel engine may have a different MSRP than the base chassis; contact us for current pricing compared to the standard 6.4L HEMI V8. While the gas engine delivers lower upfront acquisition costs, the diesel option provides substantial long-term value through higher torque output, extended engine life, and superior resale retention for heavy-hauling operations. Commercial buyers evaluating total cost of ownership should calculate fuel consumption, daily trailering weights, and annual mileage before selecting an engine. The 6.4L HEMI V8 is ideal for lower-mileage fleets, municipal utility fleets, or applications where high payload is required but heavy trailer towing is infrequent. Lower upfront vehicle cost keeps initial fleet capital low while offering dependable performance backed by a limited powertrain warranty. For high-mileage fleets pulling heavy gooseneck trailers, the 6.7L Cummins Turbo Diesel repays its initial investment over time. Diesel engines burn less fuel under heavy towing loads, and the integrated exhaust brake reduces brake pad wear during downhill engine braking. Top-load oil filtration and integrated fuel filtration systems simplify routine shop servicing and keep fleet maintenance schedules on track. Resale values for diesel commercial trucks remain exceptionally strong in the commercial marketplace. When fleet owners cycle out equipment after four or five years, diesel chassis cabs routinely command higher trade-in values that offset a significant portion of the initial powertrain upgrade cost. You can view our current new Ram chassis inventory to compare gas and diesel chassis pricing side by side. What Business Incentives and Fleet Programs Does Ram Offer Commercial Buyers? Ram supports commercial buyers through the BusinessLink program, which offers equipment upfit allowances, commercial fleet incentives, priority service scheduling, and specialized financing structures. Eligible business owners purchasing a new Ram 4500 can qualify for up to $1,000 in On-The-Job allowances toward commercial equipment installation or custom graphics.

What I Tell Local Contractors About Managing and Operating a RAM 4500 Chassis Cab ## What Should Every Commercial Owner Know About Operating the Ram 4500 Chassis Cab? Operating a Ram 4500 Chassis Cab in Class 4 commercial service gives business owners a 16,500-pound GVWR workhorse that standard Class C licensed drivers can operate legally without a Commercial Driver's License (CDL), provided the combination trailer rating stays under 10,000 pounds. Driven by an available 6.7L Cummins turbo-diesel delivering 800 lb-ft of torque, this chassis pairs up to 28,550 pounds of diesel towing capacity with heavy-duty 50,000-PSI steel C-channel frame rails designed for severe-duty upfitting. When local fleet managers come into our Junction City showroom for a consultation, the question I hear most often centers on balancing maximum hauling strength with licensing efficiency. The single-vehicle CDL mandate threshold established by federal regulations sits at 26,001 pounds Gross Vehicle Weight Rating (GVWR). Because the Ram 4500 Chassis Cab sits comfortably beneath that boundary at 16,500 pounds GVWR, business owners can assign regular crew members to drive heavy equipment, transport materials, and maneuver vocational bodies. That saves significant payroll overhead and avoids complex commercial driver compliance tracking. However, total combination weight requires careful mathematical tracking. Under Federal Motor Carrier Safety Administration rules, 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 instance, pairing a 16,500-pound GVWR Ram 4500 with a 12,000-pound equipment trailer produces a combined rating of 28,500 pounds, requiring a CDL driver. Choosing a trailer rated at or below 9,500 pounds keeps total GCWR at 26,000 pounds or less, preserving non-CDL status for daily operations. If you need help calculating your combination weight before buying, you can always give our commercial team a call to review your fleet requirements.

What Are the Fluid Capacities and Fuse Box Locations on the Ram 4500 Cummins Diesel? Where Can Owners Access the Ram 4500 Owner's Guide and Commercial Support? What Is the Gross Vehicle Weight Rating (GVWR) of a Ram 4500 Chassis Cab? Class 4 commercial vehicles like the Ram 4500 Chassis Cab are defined by a Gross Vehicle Weight Rating ( GVWR) of up to 16,500 pounds, making it ideal for medium-duty applications. Depending on engine selection and cab layout, maximum chassis payload ranges up to 9,390 pounds with the 6.4L HEMI V8 gas engine and up to 8,560 pounds with the 6.7L Cummins turbo-diesel. Achieving severe-duty payload ratings requires a heavy-duty structural foundation. The Ram 4500 is engineered 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. Key component ratings supporting severe-duty payloads include: Heavy-duty front axle rated up to 7,000 pounds GAWR to support heavy front-mounted equipment or snowplows Commercial rear axle assembly supporting up to 12,000 pounds rear GAWR to absorb heavy vertical pin weights from gooseneck trailers Commercial-grade 15-inch disc brake assemblies engineered for repeatable heat dissipation under continuous gross weight conditions Dual rear wheel axle configurations with heavy-duty multi-leaf rear suspension designed to eliminate rear-end squat under capacity loads Navigating rolling Flint Hills grades around Manhattan demands this structural rigidity, especially when pulling high-pinnacle trailers or carrying mounted crane bodies. Contractors evaluating new equipment can explore our complete selection of new Ram chassis cabs or review our dedicated commercial vehicle inventory to compare chassis configurations. For businesses replacing older fleet units, checking our pre-owned commercial truck inventory provides alternative commercial options across various weight classes.

Keeping current work trucks operating at peak efficiency is equally vital, which is why our service department offers a convenient online service scheduler for routine maintenance and commercial inspections. How Does Ram 4500 Towing Capacity and PTO Capability Compare to the Ford F-450? The Ram 4500 Chassis Cab achieves a maximum diesel towing capacity of up to 28,550 pounds and a Gross Combined Weight Rating ( GCWR) of 37,500 pounds, matching Class 4 rivals while offering superior upfit flexibility through dual-sided Power Take-Off ( PTO) mounting. Under the hood, the 6.7L Cummins turbo-diesel inline-six engine generates 800 lb-ft of torque low in the RPM band. Unlike V8 diesel configurations found in competing trucks like the Ford F-450, the inline-six design utilizes fewer moving parts, larger connecting rod bearings, and a forged steel crankshaft. This produces sustained pulling power when accelerating heavy equipment trailers from a complete stop on unpaved grades. A major commercial advantage for the Ram 4500 is its transmission-integrated Power Take-Off ( PTO) capability. Mated to the heavy-duty AISIN six-speed automatic transmission, the Ram PTO system offers left-side and right-side mounting access. This dual-sided flexibility allows body builders to mount hydraulic pumps on either side of the transmission case, simplifying line routing for dump bodies, utility cranes, and tow booms while avoiding hot exhaust components. Additionally, the factory Vehicle System Interface Module ( VSIM) provides over 70 hardwired circuits to connect aftermarket cab switches, safety interlocks, and engine speed controls seamlessly. When custom upfits require specialized maintenance, replacement parts, or electrical harnesses, our commercial parts department supplies genuine OEM components engineered for heavy-duty Ram chassis platforms. What Tax Incentives and Deductions Apply to a Commercial Ram 4500 Purchase? IRS Section 179 tax deductions provide a significant financial incentive for businesses buying vehicles like the Ram 4500 Chassis Cab, which qualifies due to its GVWR exceeding 6,000 pounds. Under Internal Revenue Code Section 179, vehicles built with a Gross Vehicle Weight Rating over 6,000 pounds qualify for accelerated depreciation treatment. Rather than writing off the chassis asset over several years, eligible commercial operations can deduct the full vehicle purchase cost during the tax year it is acquired and placed into service. Business owners should consult their CPA or tax professional to confirm specific eligibility details for their company. Regarding federal electric vehicle tax credits, buyers should note that historic federal clean vehicle credits (such as IRC §30D, §25E, and §45W) were terminated under Public Law 119-21 for vehicles acquired after September 30, 2025. Present-day commercial purchases of heavy-duty gas or diesel chassis cabs rely primarily on Section 179 and standard commercial depreciation schedules for tax optimization. To streamline commercial acquisitions, enrolled business owners can also access Ram BusinessLink benefits, including: Priority commercial service queuing to minimize vehicle downtime on active job sites Dedicated commercial account specialists familiar with vocational vehicle specifications Commercial lines of credit that keep business vehicle financing separate from personal credit Terminal Rental Adjustment Clause (TRAC) leasing options structured for business cash flow Business owners interested in expanding their commercial vehicle fleet can get pre-approved for commercial financing online to review available rates and payment structures before visiting the showroom. What Are the Fluid Capacities and Fuse Box Locations on the Ram 4500 Cummins Diesel? The 6.7L Cummins turbo-diesel engine in the Ram 4500 takes 12 quarts of engine oil with a filter change and holds roughly 6 gallons of coolant in its heavy-duty cooling system. Main electrical fuses are housed in the Power Distribution Center in the engine compartment beside the battery, while an auxiliary interior fuse panel is positioned under the driver-side instrument panel. Proper fluid maintenance and electrical circuit awareness ensure long-term reliability for heavy-duty work trucks. For routine engine servicing on the 6.7L Cummins turbo-diesel, fluid capacities include: Engine Oil: 12 quarts (11.4 liters) with oil filter replacement Engine Cooling System: Approximately 6 gallons (21.5 liters) total capacity Fuel Tank: Standard 52-gallon rear frame-mounted tank (optional 22-gallon auxiliary tank available) Diesel Exhaust Fluid (DEF) Tank: 9 gallons total capacity Locating electrical fuses quickly prevents unnecessary downtime during field operations. The Ram 4500 features a main Power Distribution Center (PDC) located under the hood on the driver's side near the battery tray. This panel contains high-amp fuses and relays for engine functions, braking systems, and primary lighting. A secondary interior fuse block sits beneath the driver-side instrument panel, housing lower-amp fuses for cabin electronics, auxiliary switches, and infotainment displays. When routine oil service is completed, resetting the oil life indicator on the instrument cluster takes only a few seconds: Turn the ignition switch to the ON/RUN position without starting the engine. Use the steering wheel directional controls to navigate to the Vehicle Info menu on the digital cluster display. Scroll through the submenu to locate the Oil Life screen.
