RAM Rebel TRX – Supercharged 575hp Off-Road Monster!!!


The Ram Rebel TRX concept debuted on the same day Ford announced power and torque specs for the 2017 F-150 Raptor (450 hp and 510 lb.ft). Ram steps the game up even higher with the Rebel TRX, putting a 575-hp 6.2-liter supercharged HEMI V8 engine to work.

“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.

Powertrain
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 aggressive 37-inch tires.

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.

Engineering
The Ram Rebel TRX has an exterior design that radiates focused aggression, which is only trumped by what lies under its skin. The concept was built around suspension and frame prerequisites. Equally important was adapting as many systems from the standard Ram 1500 as possible to ensure durability and proper function.

The high-strength steel frame structure of the Ram Rebel TRX is virtually unchanged when compared to a standard Ram 1500. The frame uses low-torsion attributes that increase durability, stability and handling precision.
A 40 percent increase in suspension travel and 37-inch tires contribute to incredible ground clearance. This combination allows the TRX concept to overcome surface obstacles at high speed.

The front suspension incorporates custom-built upper and lower A-arms with special attention to caster and camber angles during suspension cycling. Overall, front- and rear-wheel travel is increased to more than 13 inches from the standard 9 inches. The front load is managed by a state-of-the-art, adjustable, performance coil-over shock with internal bypass.
The result is a smooth ride over smaller bumps, and when the bumps become mounds, the reaction speed and heat dissipation is unbeatable, softening the impact on occupants and maintaining the tire-to-ground contact.

The Ram 1500 uses an exclusive, best-in-class link coil rear suspension system that shares basic architecture with the fastest off-road trucks in desert racing. The frame’s hard points for the five-link suspension system are unchanged and allow the rear axle travel to span up to 13 inches, while standard rear-wheel travel on the Ram 1500 is 9.25 inches. New 2.5-inch bypass shocks use factory upper and lower shock mounts. The standard rear coils are swapped for performance springs located in the factory-spec positions.

To provide incredible stopping power, the factory hydraulic-boost compensation unit enhances brake pedal feel and performance during emergency stop events. Baer brakes six-piston monoblock calipers mounted to 15-inch rotors equip the front. The rear uses six-piston calipers with 14-inch rotors.

High-speed off-road truck racing teams commonly use a 37-inch tire for its height and durability. Tires with 37 inches of height, 13.5 inches of width, aggressive treads and 10-ply design are assigned the task for Rebel TRX.
