2015 Ram 2500

Ram takes heavy-duty towing and hauling seriously. With the 2015 model year Ram 2500 and 3500 Heavy Duty, the truck world's "King of the Hill" further adds to its most-capable claims.

Working closely with Cummins, a more aggressive fuel delivery and turbo boost calibration to the 6.7-liter I-6 produces an additional 15 lb.-ft. of torque.

This improvement places the coveted engine ahead of the competition with 865 lb.-ft. of torque. The Ram 3500 continues towing leadership at 30,000 pounds and adds a new notch in its belt with a chart-topping payload of 7,390 pounds.

Meanwhile, the 6.4-liter HEMI V-8 Ram Heavy Duty delivers best-in-class horsepower and best-in-class torque among pickups with gasoline engines. Compelling numbers tell the story of the 16-valve engine with 410 horsepower at 5,600 rpm and a peak torque rating of 429 lb.-ft. at 4,000 rpm.

Other engine options include the 5.7-liter HEMI V-8, standard equipment for the Ram 2500 and 3500 (SRW). The engine produces 383 horsepower at 5,600 rpm and generates peak torque of 400 lb.-ft. of torque at 4,000 rpm. The 5.7-liter HEMI V-8 is mated to a six-speed automatic transmission.

Heavy Duty trucks generally have suspension equipped for constant, heavy payloads. This leads to a harsher ride when unloaded. The Ram 2500 takes lessons learned from the Ram 1500 with a segment exclusive five-link coil rear suspension system. Loaded or unloaded, the 5-link coil system provides best-in-class ride and handling.

The Ram 3500 continues the rear Hotchkiss leaf spring system, but offers a supplemental air suspension system. Engineers were able to soften the leaf springs, allowing for more unladed suspension movement- even with a best-in-class 30,000-pound trailer.
