Twenty-five years ago this month, Ram and Cummins changed the face of heavy-duty pickup trucks forever. Together, the two companies have succeeded by combining dominant truck engineering and superb diesel powertrain design. The result, competitors continue to chase the legacy which began in 1989 and Ram’s 2014 Heavy Duty and Chassis Cab truck lines grip best-in-class titles in the No. 1 purchase reason: capability. 

“Ram and Cummins are names synonymous with power, quality and durability. We’ve enjoyed a successful relationship and remained leaders in the diesel pickup market for 25 years,” said Reid Bigland, President and CEO — Ram Truck Brand, Chrysler Group LLC. “The numbers don’t lie. Backed by a Cummins engine, our Ram Heavy Duty is King of the Hill with 30,000 lbs. of towing capacity – three tons more than the closest competitor and our flagship Chassis Cab trucks hit Gross Combined Weight Ratings of up to 37,500 lbs.”

When first introduced in 1989, the Dodge Ram 3500 with the 5.9-liter Cummins Turbo Diesel engine produced 160 horsepower and 400 lb.-ft. of torque. Today’s 6.7-liter Cummins Turbo Diesel available in the Ram 2500 and 3500 Heavy Duty pickups and Ram 3500, 4500 and 5500 Chassis Cab trucks delivers up to  385 horsepower and a ground shaking 850 lb.-ft. of torque – more than any competitor.

“The Cummins and Ram Truck partnership has created a legendary package over the last 25 years and we appreciate their continued loyalty to Cummins,” said Dave Crompton, Cummins Vice President and General Manager – Engine Business. “This commitment to our partnership allows us to focus on delivering best-in-class performance, reliability, and durability for the heavy-duty pickup market. The Cummins and Ram brands continue to provide a terrific combination for our customers.”
