Ram Truck has announced a series of upgrades to its heavy-duty truck lineup that will give it claimed outright class supremacy in trailer towing.

Now boasting the ability to pull a segment-leading 22,700 lb (10,297 kg) maximum trailer weight, the one-tonne Ram 3500 Heavy Duty will get a performance boost to its 6.7-litre Cummins Turbo Diesel Engine that will increase its torque to 800 lb/ft and be upfitted with a package of components that will increase its gross combined weight rating (GCWR) to an unsurpassed 30,000 lbs (13,608 kg).

A new powertrain control module (PCM) with revised performance calibration allows the High-Output 6.7-litre, six-cylinder Cummins Turbo Diesel to reach peak torque at 1,600 rpm and exceed the previous model’s output from 1,200 through 2,800 rpm.

While peak horsepower remains unchanged (350 @ 3,000 rpm), the engine’s new calibration delivers more than 40 additional horsepower at typical highway cruising speeds.

Behind the powerful, High-Output Cummins lies a new higher-rated torque converter.

In addition to the new PCM and torque converter, the 800 lb/ft Cummins-powered Ram Heavy Duty trucks receive a new crankshaft damper, reducing engine noise and vibration (NVH).
