Which Ram Pickups Have the Cummins Diesel Engine, and How Much Are They?

The Cummins name for diesel engines is legendary. Cummins has made powerful diesel engines since 1924, but today the only trucks that you don’t need a CDL to drive with a Cummins are Ram pickup trucks. About 75% of all Ram 2500 and 3500 Heavy Duty trucks are sold with a Cummins turbo diesel. Ram Cummins diesel trucks come in 2500 and 2500 heavy-duty versions, and the 3500, 4500 and 5500 chassis cabs. But most people opt for the 2022 Ram 2500 HD for its mix of heavy-duty abilities and stellar interior. For more than 30 years the Cummins name has gone hand-in-work glove with Ram trucks.

And getting slaughtered in the market. So, in 1989 Dodge partnered with Cummins and the company started offering a six-cylinder turbo diesel from Cummins. The original 5.9-liter turbo-diesel wasn’t just powerful, with 400 lb.-ft. of torque, it was groundbreaking because it was the first time a turbo had shown up on a consumer diesel truck.
