August 26, 2014 – This week, Ram launched the 2015 model year for the heavy-duty 2500 and 3500, with the latter boasting a increased torque rating of 865 lb-ft and payload capacity of 7390 lb while maintaining a maximum tow rating of 30,000 lb.

Besides a 6.4L HEMI V8, other engine options include the 5.7L HEMI V8, standard equipment for the Ram 2500 and 3500 (SRW). The engine produces 383 hp at 5600 rpm and generates peak torque of 400 lb-ft at 4000 rpm. The 5.7 is mated to a 6-speed automatic transmission. The 6.7L Cummins Turbo Diesel I-6 is available in three versions.

Ram heavy-duty trucks feature frames built with 50,000 psi steel, including eight separate cross-members, hydroformed main rails and fully boxed rear rails. Chassis controls on the HD promise to reduce noise, vibration and harshness, and improve ride and handling characteristics.

The trucks feature a factory-installed seven-pin trailer tow connector in the truck bed, included with the optional fifth wheel or gooseneck tow prep package. Additionally, Ram features a standard Class 5 receiver hitch with 4-pin and 7-pin connectors on the bumper. A tailgate handle-mounted, rear high-definition camera backup system is available, as well as cargo-view camera located in the centre high-mount.
