About 2012 Ram 3500 The 2012 Ram Truck is about capability, including powertrain, towing and payload capacities, driving dynamics, premium amenities and styling that truly make it the ultimate heavy-duty pickup truck. Ram 2500 and 3500 Heavy Duty pickups incorporate some of the design cues from the Ram 1500. The Ram Heavy Duty pickup's larger grille incorporates a taller hood that includes louvers on each side. Ram Truck and Cummins have developed an enhanced High Output Turbo Diesel offering an unsurpassed 800 lb.-ft. of torque. Additionally Ram HD also has a Max Tow package option for the Ram 3500 with a 22,750-lb. maximum trailer weight and up to class-leading 30,000-lb. Gross Combined Weight Rating. The backbone of the 2012 Ram Heavy Duty pickup is a hydro-formed, fully boxed frame with advanced torsional rigidity and stiffness. A coil-spring suspension setup is used in the front of the vehicle, while the multi-leaf spring design is maintained in the rear for heavy-duty capability. Towing capability is a strong suit of the new 2012 Ram 2500 and 3500 pickups, with a standard exhaust brake (diesel-equipped models). This feature reduces brake fade, prolongs brake life and provides confidence and safety when hauling heavy loads on downhill grades. The 2012 Ram Heavy Duty has the available, legendary 6.7-liter Cummins High Output Turbo Diesel engine, which produces 350 horsepower and a class-leading 800 lb.-ft. of torque at only 1,500 rpm. Backing up the available 6.7-liter diesel engine is a choice of a standard, class-exclusive G56 6-speed manual transmission or an available 6-speed automatic transmission. The other choice for 2012 Ram Heavy-Duty customers is the standard 5.7-liter HEMI V-8 gasoline engine, which delivers 383 horsepower and 400 lb.-ft. of torque.
