Ram installed a supercharged 6.2-litre V8 under the bonnet, providing a massive 575hp to all four wheels via a Torqueflite eight-speed automatic gearbox. The Rebel TRX concept is now able of triple digit speeds, even when traveling on surfaces other than paved roads. 

In order to cope with the increased horsepower and become a true performance pickup truck, the new Rebel TRX concept features a Dynatrac Pro 60 rear axle with an electronically limited slip differential and 1.5-inch axle shafts. The front axle is a standard item, fitted with custom CV half-shafts to allow a wider track. The suspension travel was increased by 40 percent and a set of 37-inch tires contribute to a massive ground clearance that measures more than 13 inches. RAM had to widen the body in order to accommodate the huge tires.
