Starting with the 2018 model year, the Ram 3500 will offer a segment-leading 930 pound-feet of torque.

The American automaker worked closely with Cummins to improve the 6.7-liter diesel engine, allowing it to produce an additional 30 lb-ft of torque. The updates to the engine include higher boost limits through a variable geometry turbo and flow rate increases through the fuel delivery system.

In addition, Ram announced a 30,000-lb fifth-wheel towing uprating that is made possible by an in-house hitch design from Ram Engineering. The upgraded hitch lets the Ram 3500 haul the heaviest trailers in the industry, allowing customers to move away from Class 4 and Class 5 trucks for heavy fifth-wheel hauling. Pricing for the newly-engineered hitch design is $1,395.

“Ram maintains capability leadership by delivering the highest-ever torque rating for a pickup truck and heaviest fifth-wheel trailer towing capacity,” said Mike Manley, head of Jeep & Ram Brand, FCA Global. “We understand the attributes most important to our customers within the heavy-duty segment; they demand hard-working, long-lasting capability.”
