How Much Can a 2026 Ram 3500 Cummins Diesel Tow?
The 2026 Ram 3500 with the available High-Output 6.7-liter Cummins® Turbo Diesel tows up to 36,610 pounds. That figure requires a dual-rear-wheel model with a 3.42 axle ratio and a fifth-wheel or gooseneck hitch. Single-rear-wheel models with the Cummins diesel reach a maximum tow rating of 26,080 pounds.
The peak 36,610-pound rating applies to one build. Ram rates that maximum on a Dual Rear Wheel (DRW) model in 4x4. It carries a 14,000-pound GVWR and a Gross Combined Weight Rating (GCWR) of 45,000 pounds. Those ratings are what give the truck room for large agricultural, commercial, or recreational trailers.
Pulling a standard bumper-hitch trailer? Conventional receiver towing on the 2026 Ram 3500 tops out at 23,000 pounds. Above that weight, Ram requires a fifth-wheel or gooseneck hitch. The choice between single-rear-wheel (SRW) and dual-rear-wheel builds comes down to tongue weight and total trailer mass. SRW trucks are easier to maneuver day to day. DRW trucks add a wider rear contact patch that steadies heavy loads over long miles.
Every rating below is a Ram figure for a properly equipped truck, calculated to the SAE J2807 standard. Your specific truck's numbers live on its door-jamb label. Our sales specialists can pull those for any unit on the lot, and you can find our showroom on 29 Palms Highway.

What Are the Engine Options for the 2026 Ram 3500?
The 2026 Ram 3500 comes with two engines. There is no standard-output diesel in the 3500 lineup.
Standard 6.4L HEMI® V8
The 6.4-liter HEMI® V8 produces 405 horsepower at 5,600 RPM and 429 lb-ft of torque at 4,000 RPM. It pairs with an eight-speed automatic and carries the highest payload ratings in the lineup. Heavy-equipment haulers usually step up to diesel anyway, because of where the torque arrives.
Available High-Output 6.7L Cummins® Turbo Diesel
The High-Output Cummins® raises output to 430 horsepower at 2,800 RPM and 1,075 lb-ft of torque at 1,800 RPM. That torque peak sits low in the rev range. It lets the truck move heavy loads smoothly without straining the drivetrain. The engine pairs exclusively with the TorqueFlite® HD eight-speed automatic, which is built to handle its output and supports second-gear takeoffs for smoother starts under load.
What Changed for 2026
The Ram 3500 powertrain carries over for 2026. The High-Output Cummins® remains rated at 430 horsepower and 1,075 lb-ft of torque, which Ram lists as best-in-class available base diesel torque. The notable change is on the chassis side: select Ram Heavy Duty models receive an increase in Gross Vehicle Weight Rating of up to 850 pounds, achieved through revised testing and certification procedures. Ram also expanded the Heavy Duty lineup with the Ram 2500 Black Express and the first Ram 2500 Warlock, though both of those are 2500 models rather than 3500s.
Snowplow Prep comes standard on the Ram 3500, adding a 220-amp alternator and snowplow prep wiring. For extra underbody protection, a Transfer Case Skid Plate is available on 4x4 models.
| Specification | 6.4L HEMI V8 | High-Output 6.7L Cummins Turbo Diesel |
|---|---|---|
| Horsepower | 405 hp at 5,600 RPM | 430 hp at 2,800 RPM |
| Torque | 429 lb-ft at 4,000 RPM | 1,075 lb-ft at 1,800 RPM |
| Transmission | 8HP75-LCV eight-speed automatic | TorqueFlite HD eight-speed automatic |
| Maximum towing | 18,150 lbs | 36,610 lbs |
| Maximum payload | 7,590 lbs | 6,050 lbs |
Which one you need depends on the work. The HEMI® handles moderate trailers and wins on payload. The High-Output Cummins® is the pick for multi-car carriers, heavy machinery, and oversized fifth-wheel campers. If the build you want is not on the lot, our team can help you custom-order the proper truck.
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.

How Do Fifth-Wheel, Gooseneck, and Payload Capacities Compare?
Conventional Hitch vs. Fifth-Wheel and Gooseneck
Hitch type decides how much of the truck's capacity you can actually use. Conventional bumper towing caps at 23,000 pounds on the Ram 3500. The Class V receiver is rated to 2,300 pounds of tongue weight, up from 2,000 pounds on the Ram 2500. Past 23,000 pounds, Ram requires an in-bed hitch.
The available Fifth-Wheel/Gooseneck Tow Prep Group handles that. It adds factory-installed mounting provisions engineered into the truck's structure. It also adds a seven-pin wiring harness in the bed and a twelve-pin connector with an auxiliary Mopar® camera. A fifth-wheel or cargo-view camera is available with it.
Payload by Engine
Payload works inversely to engine weight. The Cummins® diesel adds mass over the front axle, so diesel builds carry lower payload ratings than gas builds. The 6.4-liter HEMI® V8 reaches up to 7,590 pounds in a Regular Cab 4x2 DRW. The High-Output Cummins® reaches up to 6,050 pounds in a Regular Cab 4x4 DRW.
How Pin Weight Eats Into Payload
Pin weight is the number most buyers underestimate. A fifth-wheel or gooseneck trailer puts its pin weight directly into the truck bed, where it counts against payload alongside passengers and cargo.
Ram's 2026 tow and payload chart sets recommended tongue weight for a conventional hitch at 10 percent of gross trailer weight. For fifth-wheel and gooseneck trailers, Ram publishes no percentage. It instead directs owners never to exceed any manufacturer rating, including payload and GAWR. That makes payload the number to watch. On a DRW Cummins® build rated at 6,050 pounds, a 3,600-pound pin weight leaves roughly 2,450 pounds for everyone and everything else in the truck. Trailer weight and payload ratings are mutually exclusive, so a truck cannot deliver its maximum towing and its maximum payload at the same time.
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.
Is the 2026 Ram 3500 Right for Heavy Towing?
Suspension and Braking Under Load
The Ram 3500 uses a rear Hotchkiss leaf-spring suspension. It is the feature that most sets the 3500 apart from the coil-sprung Ram 1500 and Ram 2500, and it is tuned to resist sag under heavy tongue weights.
The Class-Exclusive available Auto-Level Rear Air Suspension adds stability by holding rear ride height under load. That keeps steering response consistent and headlights aimed correctly. On long descents, the available Automatic Smart Exhaust Brake helps control speed and reduces wear on the wheel brakes. Heavy-duty four-wheel disc antilock brakes are standard.
Trailering Technology
Available Uconnect® touchscreens run up to 14.5 inches, which Ram lists as largest-in-class. Smaller 12-inch and 8.4-inch displays are offered depending on trim. The available 12-inch Digital Cluster Display is separate, and it runs the cluster-activated Trailer-Light Check Out routine and displays trailer tire pressure readings.
- Available Trailer Reverse Steering Control, which manages steering input while you guide the trailer with a console knob
- Available 360-Degree Surround View Camera, which draws on five cameras and includes Trailer Reverse Guidance and a cargo view camera
- Available Digital Rearview Mirror 3.0 with side camera integration
- Available Trailer Tire Pressure Monitoring for up to four trailers
- Available Blind Spot Monitoring with trailer coverage and Rear Cross Path Detection
Two driver aids come standard rather than optional. Adaptive Cruise Control is standard and class-exclusive on Ram Heavy Duty. Forward Collision Warning Plus with automatic emergency braking is standard as well. The Electronic Trailer Brake Controller is standard too. Everything in the list above is available equipment, so confirm it on the specific truck you are considering.
Driver-assistance and advanced safety systems are supplemental aids and are not substitutes for safe and attentive driving. Availability, operation, and effectiveness vary by trim and equipment and depend on factors including road, weather, traffic, and vehicle condition. Always keep your hands on the wheel and your eyes on the road. See your owner's manual for system limitations and details.

Common Questions About 2026 Ram 3500 Towing Performance
What warranty coverage comes with the 2026 Ram 3500 Cummins diesel?
The 2026 Ram 3500 comes with a 3-year/36,000-mile basic limited warranty. Ram's 10-year/100,000-mile Powertrain Limited Warranty applies to 2026 model-year vehicles, including Cummins-powered Heavy Duty trucks. That coverage applies to the original owner who purchased the truck new at retail from an authorized Ram dealer, and it is non-transferable. Second and subsequent owners fall back to 5 years or 60,000 miles on gas powertrains and 5 years or 100,000 miles on diesel engines.
What axle ratio is required for the maximum towing capacity?
Reaching the maximum 36,610-pound towing rating requires the 3.42 axle ratio paired with the High-Output 6.7-liter Cummins Turbo Diesel, dual rear wheels, and a 4x4 chassis with a 14,000-pound GVWR and a 45,000-pound GCWR.
Why does the Ram 3500 have a higher payload capacity with the gas engine than the diesel?
The 6.7-liter Cummins Turbo Diesel assembly weighs substantially more than the 6.4-liter HEMI V8. Because Gross Vehicle Weight Rating sets an upper limit on the combined weight of the truck and its contents, the heavier diesel engine consumes more of that allowance. That leaves less remaining capacity for bed payload.
Does conventional hitch towing allow you to tow 36,610 pounds?
No. Conventional receiver hitches are rated to a maximum of 23,000 pounds on the Ram 3500, with a Class V tongue weight limit of 2,300 pounds. Trailers above 23,000 pounds require a fifth-wheel or gooseneck hitch installed in the truck bed, supported by the Fifth-Wheel/Gooseneck Tow Prep Group.
What are the primary cab and bed length options for the Ram 3500?
The 2026 Ram 3500 is available in Regular Cab with an 8-foot bed, Crew Cab with a 6-foot-4-inch or 8-foot bed, and Mega Cab with a 6-foot-4-inch bed. The Mega Cab is offered exclusively with four-wheel drive and comes standard with the 3.42 axle ratio, and it offers a Class-Exclusive forward fold-flat rear seat.
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.
