The rear axle is a ProRock 60-based Mopar/Dynatrac/AIM portal axle assembly. It has been fitted with an ARB Air Locker, 4.10:1 ratio gears, and dual Wilwood brake calipers at each wheel. One caliper at each wheel serves as standard brakes while the other caliper at each wheel serve as parking brakes. The rear suspension is also similar to the front with King remote-reservoir coilover shocks and Teraflex standard-length JK-application control arms. Positioned behind the axle is a GenRight 18-gallon aluminum fuel tank. The fuel tank and the spare tire were specifically positioned behind the rear axle to help balance the vehicle.
