Ram Heavy Duty Truck fans who also love the 6.7-liter Cummins Turbo Diesel engine, well, this is your day.

Cummins Inc. has announced a multiyear extension on its contract with Chrysler Group LLC to supply the legendary mill for Ram Heavy Duty Pickup Trucks. The engine is optional on 2011 Ram 2500/3500 models, and standard on the 2011 4500 and 5500 Chassis Cabs. It churns out 350 horsepower (261 kW) at 3,000 rpm and 650 lb.-ft. of torque (881 Nm) at a mere 1,500 rpm.

The Cummins Turbo Diesel-equipped Ram 2500 and 3500 pickups met 2010 EPA emissions standards as early as 2007. As a result, Ram Heavy Duties will be the only 3/4 and 1-ton pickup trucks available without a selective catalytic reduction system that requires the owner to add diesel exhaust fluid.

The first Cummins Turbo Diesel was placed in the 1989 Ram and was a smashing success as Cummins points out in its press release, which you can find here.
