Notes

Computer Programming: 2012 and newer vehicles require a computer programmer, such as the AEV ProCal Module to reset the gear ratio and tire height in the vehicle's computer for proper function of the vehicles stability control and transmission shift points

Brake Components: Does not include rear disk brake rotors or calipers, mounting brackets are designed to reuse the stock rotors and calipers from the vehicle.

Wheel Bolt Pattern: Axles are dual patterns drilled, 5 on 5” with wheel studs installed and 5 on 5 ½” (holes only) to match a RockJock 60 front

Wheel Studs: Includes 1/2 inch wheel studs

Overall Width: Axle width is 65.4 inches (stock JK) between wheel mounting surfaces
