Cummins Diesel Engine - Repair, Service & Maintenance


Cummins-RAM History: A Legacy of Power and Reliability

Cummins engines have been an option in RAM pickups since 1989. For more than 25 years, Cummins worked with RAM to provide drivers the toughest, most reliable trucks on the road. And

from the beginning, Circle M Truck Repair in Bakersfield CA., has been servicing all

Cummins engines.

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.

The Cummins-RAM partnership grew through the years... 

Major Milestones

-       1989: introduced first Cummins-powered RAM

-       1996: exceeded 200-horsepower

-       2001: surpassed 500-pound-feet torque

-       2007: launched 6.7-liter, 350-horsepower engine

-       2013: reached 385-horsepower, 850 pounds-feet torque

From the 5.9-liter, 160-horsepower beginnings to the 6.7-liter, 385-horsepower engines available in today’s RAM pickups, Cummins and RAM lead the way in innovation, power and durability. Circle M Truck Repair in Bakersfield California leads the way in repair, service and maintenance of all diesel engines.
