Commercial Powertrains: 6.7L Cummins® Turbo Diesel vs. 6.4L HEMI® V8
The 2026 Ram Chassis Cab lineup is engineered with two proven commercial powerplants designed to handle continuous high-stress cycles across Wyoming's challenging topography and climate. Whether your work calls for daily local runs or heavy regional equipment transport along the I-80 corridor, Ram provides purpose-built capability with factory transmission Power Take-Off (PTO) engineering.
6.7L Cummins® Turbo Diesel I6
Delivering 360 horsepower at 2,800 RPM and a massive 800 lb-ft of torque at just 1,500 RPM. Producing high torque at low engine speeds reduces internal component heat and mechanical wear during heavy towing. Paired with the commercial-grade Aisin heavy-duty 6-speed automatic transmission featuring wide gear ratios and dedicated cooling loops.
6.4L HEMI® V8 Gas Engine
Standard commercial gasoline performance generating 370 horsepower (375 hp on Class 3) and 429 lb-ft of torque. Paired with the TorqueFlite 8HP75 8-speed automatic transmission, offering responsive throttle control, lower initial acquisition cost, and simplified fleet maintenance for service and stake bodies.
Dual-Sided Power Take-Off (PTO)
Both transmission pairings offer factory left- and right-side transmission-mounted PTO ports delivering up to 250 lb-ft of torque output. This dual-sided design gives upfitters the necessary clearance for hydraulic pumps powering cranes, dump hoists, aerial bucket lifts, generators, and highway snowplows.
Mechanical Durability: Cummins Inline-Six Simplicity
Unlike V8 diesel architectures that utilize two cylinder heads, sixteen pushrods, and complex turbocharger plumbing tucked into the engine valley, the Cummins 6.7L inline-six design features a single solid cast cylinder head and six pistons in a straight line. This mechanical layout delivers fewer moving parts, direct manifold routing, and generous engine bay clearance. Commercial fleet mechanics can perform valve lash adjustments, fuel injector replacements, and turbo maintenance with ease, significantly cutting downtime for Carbon County fleet operators.
Ram Chassis Cab Capability Matrix: 3500 vs. 4500 vs. 5500 (4x4)
Selecting the proper commercial platform depends on your payload needs, gross vehicle weight rating (GVWR), and equipment trailering specifications. Because severe Wyoming winters and rugged job sites demand four-wheel traction, the table below outlines certified maximum 4x4 ratings across Class 3, Class 4, and Class 5 platforms.
| Model & Powertrain (4x4) | Commercial Class | Max 4x4 Towing | Max 4x4 Payload | Max GCWR | Recommended Wyoming Applications |
|---|---|---|---|---|---|
| Ram 3500 4x4 (6.4L HEMI® V8) | Class 3 | 18,520 lbs | 7,330 lbs | 33,000 lbs | Light stake beds, contractor tool bodies, landscape haulers |
| Ram 3500 4x4 (6.7L Cummins® Diesel) | Class 3 | 25,480 lbs | 6,180 lbs | 38,500 lbs | Gooseneck livestock hauling, commercial utility beds, hotshot trailers |
| Ram 4500 4x4 (6.7L Cummins® Diesel) | Class 4 | 29,370 lbs | 9,290 lbs | 37,500 lbs | Heavy mechanics service bodies with cranes, rollback wreckers, municipal dump beds |
| Ram 5500 4x4 (6.7L Cummins® Diesel) | Class 5 | 34,770 lbs | 12,050 lbs | 43,000 lbs | Severe-duty knuckle boom cranes, heavy dump bodies, oilfield maintenance, snowplows |
50,000-PSI High-Strength Steel Frame
Built for rigorous commercial work, Ram Chassis Cab models feature a 50,000-PSI high-strength steel frame with flat top-of-frame rear rails. All fuel lines, wiring harnesses, and exhaust components are routed securely through or below the frame rails, providing body manufacturers with an unobstructed, weld-ready surface. Factory-drilled holes eliminate the need for aftermarket frame drilling, preserving the structural integrity and corrosion protection of the chassis.

Section 179 Tax Deductions & Fremont Statewide Network
Managing operational costs is essential for any growing business. Because all Ram 3500, 4500, and 5500 Chassis Cab models exceed 6,000 lbs Gross Vehicle Weight Rating (GVWR), they qualify under IRS Internal Revenue Code Section 179 for accelerated depreciation. Qualifying business owners may be eligible to write off up to 100% of the purchase price on new work trucks placed into active service during the current tax year.
*Disclaimer: Tax laws are subject to change. Always consult a certified tax professional or CPA to determine how Section 179 and bonus depreciation apply to your specific commercial business structure.

Frequently Asked Questions: RAM Chassis Cab
What engine options are available on the 2026 RAM Chassis Cab?
The 2026 Ram Chassis Cab offers two commercial powertrains: a standard 6.4-liter HEMI® V8 gas engine producing 370 hp (375 hp on Class 3) and 429 lb-ft of torque paired with an 8-speed automatic transmission, and an available 6.7-liter Cummins® Turbo Diesel inline-six generating 360 hp and 800 lb-ft of torque paired with a heavy-duty Aisin 6-speed automatic transmission.
Do RAM 4500 and 5500 Chassis Cab trucks require a Commercial Driver's License (CDL)?
Not necessarily. A Commercial Driver's License (CDL) is generally required under Federal Motor Carrier Safety Regulations (FMCSR) when the vehicle or combination has a Gross Vehicle Weight Rating (GVWR) or Gross Combined Weight Rating (GCWR) of 26,001 pounds or more. Many Ram 4500 and 5500 models can be configured and operated without a CDL when keeping total combination weights below the 26,001-lb threshold, provided they are not transporting hazardous materials requiring placards or more than 15 passengers. Consult state and federal DOT guidelines for your specific commercial application.
What is the difference in towing capacity across Ram 3500, 4500, and 5500 Chassis Cabs?
Maximum towing capability scales with commercial chassis classes in heavy-duty 4x4 configurations: the Ram 3500 4x4 reaches up to 25,480 lbs towing (with the 6.7L Cummins Diesel) or 18,520 lbs (with the 6.4L HEMI V8); the Ram 4500 4x4 delivers up to 29,370 lbs max towing; and the severe-duty Ram 5500 4x4 achieves up to 34,770 lbs max towing with a GCWR of 43,000 lbs.
What is Power Take-Off (PTO) and what can it power?
Power Take-Off (PTO) is a mechanical gearbox unit mounted to the transmission that draws engine power to operate auxiliary hydraulic and mechanical equipment. Ram Chassis Cab models feature dual-sided (left and right) PTO mounting capability delivering up to 250 lb-ft of torque to run dump bed hoists, tow truck winches, knuckle boom cranes, hydraulic spreaders, and aerial bucket lifts.
What documents are needed to enroll in RAM BusinessLink?
Qualifying for RAM BusinessLink requires just one standard proof of business ownership: a Federal Employer Identification Number (EIN) document, a current state or municipal business license, active Articles of Organization (LLC), or a recent business income tax return (Schedule C). There are no membership fees or recurring dues.
What Cab-to-Axle (CA) lengths are available on Ram Chassis Cab models?
