Cummins-RAM History

Cummins engines have been an option in RAM pickups since 1989. For more than 30 years, we’ve worked with RAM to provide drivers the toughest, most reliable trucks on the road.

From our 5.9-liter, 160-horsepower beginnings to the 6.7-liter, 400-horsepower engines available in today’s RAM pickups, Cummins and RAM lead the way in innovation, power and durability.

Chrysler initially launched the RAM in 1981. Facing stiff competition from Ford and General Motors, RAM needed something unique to carve out its niche.

Cummins and Chrysler officials recognized the mutual benefit of incorporating the new Cummins B-series engine into the RAM. Cummins was a known leader in commercial vehicles, and the B-series represented the company’s first move into the medium-duty pickup arena.

Dodge masterfully engineered the RAM to accommodate the size and power of the Cummins turbo diesel engine, and the first Cummins-powered RAM hit the streets in 1989. With 400 pounds-feet of torque, it roared past the competition. This was the start of a powerful relationship which has grown through the years.
