The 2027 Ram 3500 with the High-Output 6.7L Cummins diesel tows up to 37,020 lbs. That number is 18,880 lbs more than the gas HEMI V8 configuration can pull. This page breaks down every hitch type available on the 3500, with current inventory at Fillback.
The 3500’s trailering capability rests on two distinct powertrains. The base 6.4L HEMI V8 produces 405 hp and 429 lb-ft of torque, paired to the TorqueFlite 8HP75-LCV 8-speed automatic, and pulls up to 18,140 lbs. The available High-Output 6.7L Cummins Turbo Diesel I6 pushes 430 hp and a best-in-class 1,075 lb-ft of torque at just 1,800 rpm, paired to the TorqueFlite HD 8AP1075 8-speed automatic, and stretches that ceiling to 37,020 lbs.
2027 Ram 3500 towing specifications
That diesel torque figure matters to hitch choice. Gooseneck and fifth-wheel applications load weight directly over the rear axle, and the 3500 uses an AAM 12.0-inch beam rear axle in Max Tow configurations to handle the load. The standard rear axle is an AAM 11.5-inch beam unit. Both setups use hydro-boost braking on diesel models, giving better pedal feel under heavy trailer weight than a vacuum-assist system. Payload on the diesel 3500 reaches 6,460 lbs, while the HEMI V8 version offers up to 7,580 lbs of payload when properly equipped.
2027 Ram 3500 full specs and trim breakdown
An integrated trailer brake controller comes standard across all 3500 trims. Snowplow Prep capability is also standard, which signals the reinforced electrical architecture that supports trailer lighting and auxiliary systems. The 220-amp alternator on higher trims further supports accessory and brake controller loads.

A conventional receiver hitch mounts to the frame behind the bumper and accepts a ball mount, weight-distribution head, or sway-control bar. The 3500’s robust ladder-type frame provides a solid foundation. Receiver hitches work best with conventional travel trailers, toy haulers, boat trailers, car haulers, and utility trailers. On the gas HEMI V8 3500, this is the primary hitch setup, capable of up to 18,140 lbs when properly configured with the 4.10 axle ratio. Tongue weight management and a weight-distribution hitch are required for heavier conventional trailers to keep the front axle planted and the trailer tracking cleanly.
A fifth-wheel hitch mounts in the truck bed on a kingpin coupling and distributes pin weight, typically 15 to 25 percent of trailer weight, directly over the rear axle. This setup is the standard choice for large RVs, horse trailers, and heavy livestock trailers because it puts the pivot point closer to the axle, reducing trailer sway compared to a receiver ball mount. The Ram 3500 diesel’s 37,020-lb ceiling makes it the right platform for the largest fifth-wheel trailers on the market.
For 2027, the Factory Fifth-Wheel/Gooseneck Prep Package is available across multiple 3500 trims. This package includes a factory-installed rear-axle structural crossmember with integrated mounting hardware that accommodates standard fifth-wheel rail systems. The crossmember is structural, not a bolt-on afterthought, meaning pin weight loads transfer directly into the frame rather than through the bed floor.
A gooseneck hitch uses a ball-and-coupler design mounted in the center of the bed, similar in floor placement to a fifth-wheel but with a different coupling mechanism. Gooseneck is the dominant choice for agricultural applications: livestock trailers, flatbed equipment trailers, and grain haulers. The coupler attaches to a ball typically mounted through the bed floor on a drop-hitch bracket, allowing easy removal when the hitch is not in use.
The same Fifth-Wheel/Gooseneck Prep Package that enables fifth-wheel use also preps the 3500 for gooseneck application. The factory rear-axle structural crossmember includes mounting holes for both fifth-wheel rail brackets and a gooseneck ball. For farmers hauling grain out of western Wisconsin or cattlemen moving livestock between Boscobel and Prairie du Chien, gooseneck configuration on the diesel 3500 is the practical choice. The bed-mounted seven-pin connector and mounting-hole covers complete the factory prep.
The 2027 Ram 3500 lineup runs from Tradesman through Limited Longhorn, spanning Tradesman, Black Express, Warlock, Big Horn, Laramie, Rebel, Power Wagon, Limited, and Limited Longhorn. Hitch-related hardware availability shifts meaningfully across those trims.
The available 50-gallon fuel tank, on Crew Cab models with the 8-foot bed, is a significant asset for long hauls. Less time at fuel stops means more time on-task for operators running heavy fifth-wheel or gooseneck loads across western Wisconsin.
For operators in Richland Center, Prairie du Chien, and Boscobel, the choice between hitch types comes down to what they pull.
A dairy or beef producer moving cattle on a gooseneck livestock trailer benefits most from the diesel 3500’s 1,075 lb-ft of torque at 1,800 rpm. That low-rpm torque lets the engine pull through uphill grades on Wisconsin’s rolling terrain without excessive downshifting or elevated exhaust temperatures. The 3.42 rear axle ratio paired with the TorqueFlite HD 8-speed optimizes this delivery: taller final drive ratios in gears 1 through 6 for towing confidence, and a numerically lower ratio in gears 7 and 8 for highway efficiency on longer interstate runs.
An RV owner pulling a large fifth-wheel benefits from the Trailer Reverse Steering Control and the 12-inch Digital Cluster’s Trailer Tow Pages, which display brake status and trailer tire pressure in one view. The 360-degree surround view camera system, available through the Tow Technology Group, provides a bird’s-eye reference when backing into a tight campsite.
A contractor pulling a flatbed equipment trailer on a receiver hitch benefits from the standard Automatic Smart Exhaust Brake, which uses engine braking on descents to reduce service brake heat and fade when trailing heavy loads down grades.
The available RamBox cargo management system keeps hitch accessories, safety chains, and load-binder chains secured with LED lighting and lockable access, a practical detail when unloading at a remote job site after dark.
No competitor in the one-ton segment matches the Ram 3500 diesel’s 37,020-lb tow rating with a factory fifth-wheel/gooseneck prep package installed. Rivals offer fifth-wheel and gooseneck prep as dealer-installed or aftermarket additions; Ram’s factory-installed rear-axle structural crossmember integrates the load path into the frame at the assembly stage. The 7,580-lb payload ceiling on the gas 3500 is relevant for contractors who need maximum bed load alongside a receiver hitch setup, since gooseneck pin weight reduces available payload directly.
The Trailer Reverse Steering Control is not available on every competitor truck, and the available factory mirror system with power-telescoping, power-folding, and memory is a class-exclusive feature. For buyers who hitch and unhitch multiple trailer types weekly, these features reduce setup time and operator frustration compared to trucks that require manual mirror adjustment.
