2026 Ram 5500 Fleet Work Trucks for Contractors: Towing, Payload, and Engine Specs

The 2026 Ram 5500 Chassis Cab is a heavy-duty commercial vocational platform. It is engineered for aftermarket upfitting into specialized work trucks — dump beds, service bodies, flatbeds, and tow carriers. The frame uses straight, flat rails, with rear frame strength of 50,000 psi. Maximum Gross Vehicle Weight Rating is 19,500 pounds, and maximum towing reaches 34,540 pounds when properly equipped.

Standard pickup beds limit what tradespeople and commercial fleets can haul or organize. A chassis cab provides a bare rear frame rail setup instead. Body builders can mount utility compartments, hydraulic dump bodies, or rollback platforms directly to the chassis. That adaptability lets businesses in logistics, construction, and municipal services tailor a truck to their daily workflow.

Two details govern how easily a body goes on: the rear frame dimensions and the cab-to-axle length the body requires. A third determines how easily that body’s electrical controls integrate with the cab, which is where the factory upfitter switches matter. The Ram 5500 supports that work with predrilled frame mounting holes, standard cab-to-axle lengths, a six-button auxiliary switch bank, and a rigid rear axle.

Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.

What Is the Gross Vehicle Weight Rating of the 2026 Ram 5500?

The 2026 Ram 5500 Chassis Cab carries a maximum Gross Vehicle Weight Rating of 19,500 pounds. Per Ram’s published Chassis Cab figures, maximum payload reaches 12,260 pounds with the 6.4L HEMI® V8, while Ram’s Chassis Cab capability figures list 11,530 pounds with the 6.7L Cummins® Turbo Diesel I6.

GVWR is the number fleet managers work backward from. It sets the maximum total allowable weight of the truck when fully loaded — base chassis, driver, passengers, body upfit, tools, and fuel. Note the split between powertrains. Gas configurations carry the higher maximum payload rating. Diesel configurations carry the higher maximum towing rating. Which one matters more depends on whether the body or the trailer is the heavier part of the job.

Rear GAWR 13,500 lb

Axles, Suspension, and Wheels

Every 5500 uses a 13,500-pound rear Gross Axle Weight Rating from an American Axle unit. The available Heavy-Duty Front Suspension Group raises maximum front Gross Axle Weight Rating to 7,000 pounds with the 6.4L HEMI V8 and to 7,250 pounds with the 6.7L Cummins Turbo Diesel. Suspension consists of a solid front axle with coil springs and heavy-duty shock absorbers, heavy-duty rear leaf springs, and dual rear wheels. Standard wheels are 19.5×6-inch black-painted steel. Polished aluminum is available through the Big Horn® Level 2 and Level 3 equipment groups. Tires are 225/70R19.5 all-purpose on 4×2 models, while 4×4 models pair all-purpose front tires with rear traction tires; an off-road tire is also available.

Payload and maximum trailer weight are mutually exclusive. Both vary by cab type, cab-to-axle length, drivetrain, and installed equipment. Confirm ratings for your exact build before you commit to a body. You can also review our current new vehicle specials while you spec your configuration.

Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.

Which Engine and Transmission Combination Is Best for Contractors Who Tow Daily?

The 6.7L Cummins Turbo Diesel I6 pairs with the ZF TorqueFlite® HD eight-speed automatic. It delivers 360 horsepower and 800 lb-ft of torque. That is the combination built for heavy daily towing.

Powertrain Comparison

Specification 6.7L Cummins Turbo Diesel I6 6.4L HEMI V8 (Standard)
Horsepower 360 hp 375 hp
Torque 800 lb-ft 429 lb-ft
Transmission ZF TorqueFlite HD eight-speed automatic ZF TorqueFlite HD eight-speed automatic
Maximum Towing — 4×4 34,540 lb 20,930 lb
Maximum Towing — 4×2 29,390 lb 21,230 lb
Maximum Payload 11,530 lb 12,260 lb

The Cummins is engineered for heavy commercial pulling and long duty cycles under load. It delivers peak torque at low engine speeds. That is what pulls a loaded machinery trailer or an equipment float off a job site without straining the powertrain. The TorqueFlite HD eight-speed automatic replaces the six-speed automatic used in prior model years, and it is standard with both engines on the 2026 Ram 5500.

The standard 6.4L HEMI V8 suits lighter service bodies, shorter daily routes, and lower annual mileage. Daily trailering fleets benefit from the diesel’s integrated Diesel Exhaust Brake. It reduces wear on the service brakes on extended downhill grades.

How Do Drivetrain and Configuration Affect Towing Capacity?

Maximum towing on the 2026 Ram 5500 Chassis Cab is set by drivetrain and body configuration. It is not set by add-on hardware.

Drivetrain Sets the Ceiling

A 4×4 Regular Cab with the 60-inch cab-to-axle and the Cummins diesel reaches 34,540 pounds, per Ram’s 2026 Ram 5500 Chassis Cab 4×4 engine specifications. Its Gross Combined Weight Rating is 43,000 pounds. The equivalent 4×2 diesel is rated at 29,390 pounds against a 37,500-pound GCWR, per Ram’s 2026 Ram 5500 Chassis Cab 4×2 engine specifications. That gap is the most overlooked number in chassis cab shopping.

Body configuration matters as well. GCWR is fixed, so every pound of truck is a pound of trailer you give up. Longer cab-to-axle lengths and Crew Cab bodies both reduce the rating. Spec the shortest cab-to-axle length your body actually requires.

Rear axle selection is not a variable on this truck. Every 2026 Ram 5500 uses a 4.44 rear axle ratio.

Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.
