REX is a bolt-on performance upgrade that
replaces the factory solid axle into a high-end
independent suspension system.
Its patented differential design accommodates extra-long
suspension arms and half-shafts—all while maintaining the
stock body width.
The result: up to 20 inches of wheel travel
and dramatically increased ground clearance on a standard
Jeep JK, delivering superior handling, control, and off-road
capability.
