Ford has proven that fast off-road trucks are awesome. Dodge has proven that ridiculously powerful supercharged V8s are awesome. Combining the two would theoretically be even more awesome. The Ram Rebel TRX proves that theory. The Rebel TRX is a 100-mph off-road machine with 575 horsepower, making it the most powerful half-ton truck the company has ever built.
The Rebel TRX uses a supercharged V8, it is actually a version of the supercharged 6.2-liter V8 from the Hellcat twins. However because of some new calibrations to make the engine more suited for off-road driving, it doesn’t make the full 707 horsepower of the Charger and Challenger. But the TRX engine still pushes out 575 horsepower.
Power is transferred through an 8-speed automatic transmission to all four wheels. At the back, the Rebel TRX has an electronic locking differential. The TRX also gets an updated version of the Ram’s 4×4 Performance Control System featuring Normal, Wet/Snow, Off-road and – best of all – Baja modes. The last mode will allow you to do triple digits through the desert.
Of course a powertrain like this needs chassis and tire upgrades to round out the package, and the Rebel TRX has plenty of improvements. The standard Ram 1500 frame is unchanged, but bolted to it are custom front control arms, internal bypass shocks at each corner and new springs. The changes bring suspension travel up 40% to a full 13 inches all around. It also provides enough space to fit massive 37 x 13.5-inch tires. Ram also added six-piston calipers with 15-inch discs at the front and 14-inch discs at the back.
The body is a full six-inches wider than the standard 1500 with large composite fenders to cover the massive tires. The truck also has a vented and scooped hood based on the Ram HD. The scoop was necessary to help cool the engine and provide vertical clearance for the superchager. A large sport bar was added to the back and has provisions for carrying a pair of spare tires, plus an LED light bar on top. The truck also has a big steel skid plate up front, and a sweet integrated side-exit exhaust behind the doors.
Inside, the truck gets plenty of leather, suede and carbon fiber. The front seats also have racing harnesses attached to a harness bar that spans the B-pillars. And Rebel TRX takes a page out of the Porsche playbook with Nylon-door pulls instead of handles.
Ram did say that the company is looking at the market to see if a truck like this would be a good idea, as well as the intention to offer more off-road friendly vehicles. We certainly think the Rebel TRX is a great starting point.
