RAM teases with TRX tuff truck

US truck maker RAM has teased tuff truck fans the world over with the launch of the Rebel TRX concept, an engineering, design and consumer-interest study for an extreme performance half-tonne pickup

The TRX is powered by a supercharged 6.2-litre hemi V-8 which delivers 238kWs (575hp) and equipped with a TorqueFlite eight-speed automatic transmission, a BorgWarner 44-45 transfer case and 4x4 Performance Control System offering a choice of grip modes, Normal, Wet/Snow, Off-road and Baja.

The 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 wheel wells for the aggressive 37-inch tyres.

At the back a Dynatrac Pro 60 axle spools power through an electric, selectable locker diff to 35-spline, 38mm (1.5-inch) axles.

The front suspension incorporates custom-built upper and lower A-arms with wheel travel up 101mm (four inches) front and rear to more than 330mm (13 inches).

Bypass-style shock absorbers and uprated (coil) springs are used front and rear while Canadian specialist Baer has provided six-piston monobloc brake callipers mounted to 381mm (15-inch) brake rotors up front and six-piston callipers and 355mm (14-inch) brake rotors out back.

Tyres with 37 inches of height, 13.5 inches of width, aggressive treads and 10-ply design are assigned the task for Rebel TRX. The Rebel TRX concept also features custom beadlock wheels from Mopar mounted with 10-ply 37 inch race truck tyres.

Completing the racer-inspired look the Rebel TRX carries two complete spare tyre and wheel packages with tools and a jack located in custom, lockable storage between the wheels in the bed.
