The Beautiful Ram 🔥
“With 575 supercharged horsepower and a suspension system built to withstand an all-day hammering, the Rebel TRX concept can devour the roughest terrain at more than 100 miles per hour and never look back” said Mike Manley, Head of Ram Brand, FCA – Global.
The monster engine is mated to an 8-speed automatic like the other Hellcats and uses many off-the-shelf Ram parts to manage the massive tires and power. Building a truck that can hit those kinds of off-road speeds also meant making changes to the body and the suspension. The Rebel TRX is six inches wider than a regular Ram 1500, allowing Ram to fit it with giant 37-inch tires.
The rapidly beating heart of the Ram Rebel TRX concept is a powertrain marvel. A 6.2-liter supercharged HEMI with 575 horsepower, the most powerful Ram 1500 the company has ever built, lays the groundwork of expectation.
Mated to the TorqueFlite 8HP70 eight-speed automatic transmission, new calibrations were used for the engine, transmission and drivetrain to optimize the expected high-speed off-road driving cycle.The Ram Rebel TRX concept uses Ram’s 4×4 Performance Control System with a BorgWarner 44-45 transfer case. The system employs different modes of operation: Normal, Wet/Snow, Off-road and Baja.
The Ram Rebel TRX concept uses a standard Ram 1500 front axle with an open differential and custom CV half-shafts to handle the wider track dimension. The spindles are moved forward to make room within the fender wells for the In the rear, a Dynatrac Pro 60 axle spools power through an electric, selectable locker to 35-spline, 1.5-inch axle shafts. The locker is available in all modes and commits both rear wheels to traction at the same speed, spreads the torque load and maximizes the tractive effort (power put to the ground) in full-throttle maneuvers.
