5th Gen 6.7L Cummins Specs, Background, and Information

In 2019, Ram released their new 5th Generation Cummins HD trucks after nearly a decade of the 4th generation trucks. After driving them for myself, there’s no doubt in my mind that the 5th generation Cummins is the most capable and powerful Ram truck to date! An available 6.7L High-Output Cummins engine paired with an Aisin transmission in Ram 3500s give the trucks an impressive 1,000 lb/ft of torque and 400 horsepower from the factory. Even the standard trucks are impressive, producing 850 lb/ft of torque and 370 horsepower when paired with the 68RFE automatic transmission. Horsepower and torque are just two parts of the equation however, and we’ve been getting tons of inquiries about 5th Generation 6.7L Cummins Turbodiesel specifications.

Everyone is aware of the reliability of the Cummins engine and their ability to produce and handle tons of power effectively. How do the specifications differ compared to the 4th generation Cummins though? Everything you need to know is right here in our 5th Generation 6.7L Cummins Turbodiesel specifications chart.

How Much Horsepower & Torque does a 5th Generation Cummins Make?

2019+ Ram 2500 and Ram 3500

How much horsepower and torque does a 5th generation Cummins produce? The 2019 Ram 2500 and Ram 3500 produce between 370 and 400 horsepower and 850 lb/ft to 1,000 lb/ft of torque. The differences depend on the configuration of the truck. Ram 3500 trucks equipped with the AS69RC Aisin Six-speed transmission produce 400 horsepower and 1,000 lb/ft of torque. These Aisin-equipped trucks are referred to as High-Output (HO) models. Regular Ram 2500 and Ram 3500 trucks equipped with the 68RFE transmissions will result in the lower output of 370 horsepower and 850 lb/ft of torque. To simply things for our readers, we developed a horsepower and torque specification chart for the 2019+ Ram HD trucks.

2019+ Ram 2500 & Ram 3500 Towing Capacity

The 5th Generation Cummins is a towing beast, there is no doubt about it. The 400 horsepower and 1000 lb-ft of torque in the high-output 6.7L Cummins are capable of towing just about any load you can throw at them. Depending on the truck you purchase, tow capacity can vary. Single Cab, Dually models with 4×2 and the High Output engine can tow up to 35,100 lbs. For the chart below, we are simply showing you max tow capacity figures for both the standard output and high-output trucks. For actual tow capacity and towing ratings, check your owner’s manual or contact the manufacturer.
