Some of you may remember the “TRX” name from late-model Ram trucks. This morning at the State Fair of Texas, it’s back, it’s powerful, and it’s badder than ever. The Ram Rebel TRX Concept is the current embodiment of what FCA can do when it comes to off-road performance. And while it remains a “concept” for now – this monster looks like it can be built tomorrow. Which, of course, we hope happens.
Most details are scarce at the time of this writing, but this ruby-red Rebel TRX Concept is powered by a 6.2L supercharged Hemi (but don’t call it a Hellcat) with an angry 575 horsepower mated to a TorqueFlite 8HP70 eight-speed automatic with an exhaust system that dumps out the side. Because ‘Merica, that’s why. That 575 hp power figure also makes the Ram Rebel TRX Concept the most powerful half-ton truck “from the factory.” Though, that claim will only matter if this truck actually leaves the factory, if you ask us.
Also present are enormous 37-inch Toyo M/T Open Country off-road tires with bead-lock wheels. Accommodating the meaty rubber is a six-inch wider stance. There’s a standard Ram 1500 front axle with an open differential and custom CV half-shafts to handle the wider track dimension, and the spindles are moved forward to make room within the fender wells for the Toyos. In the rear, a Dynatrac Pro 60 axle channels the power through an electric, selectable locker to 35-spline, 1.5-inch axle shafts. Ram says that the locker is available in all modes and commits both rear wheels to traction at the same speed, spreads the torque load and helps optimize putting the power to the ground in full-throttle maneuvers. To keep this beast under control, there are Baer brakes six-piston monoblock calipers mounted to 15-inch rotors up up front. The rear uses six-piston calipers with 14-inch rotors.
The suspension system offers an incredible 13-inches of wheel travel up front – that’s an increase of 40 percent from the Ram 1500, and 9.25 inches of travel in the rear. There are also 2.5-inch bypass shocks use factory upper and lower shock mounts, and the standard rear coils are swapped for performance springs located in the factory-spec positions.
As a result of the mega tires, aggressive suspension and 575 horsepower, Ram touts that the Rebel TRX Concept can achieve speeds of around 100 mph not just on-road, but off road. And if you’re going to take anything away from reading this story, it should be that.
On the inside, the front seats integrate lateral support upper bolsters with embroidered logos. All four seats are strapped with six-point harnesses, because race truck. Adding to the sportiness is an open upper glove box with elastic straps holds a sturdy TRX-labeled bag with color matched tools. Every off-road truck should have tools. Adding to the practicality is a custom camera mount is located at the rear-view mirror. On the truck bed is a sport bar covered in black anodized paint provides anchor points dedicated to the six-point harnesses and spans from B-pillar to B-pillar – formed to allow maximum possible seat travel. Lastly, a full-size spare sits openly in the truck bed.
Dear Ford and GM: Ram has officially raised the bar. But it only counts if it’s built.
