This mild lift system replaces the stock upper control arms with thick wall DOM tubular arms that feature heavy duty extended range ball joints. These ball joints provide additional strength to the vehicles suspension compared to the factory.

The factory front Coilover shocks are retained with additional ride height coming from heavy duty steel spacers to keep the stock ride. The front differential is relocated to keep CV angles proper with the new lift height while a 1/4” thick steel skid plate provides protection against offroad obstacles.

Rear lift is accomplished with 1 1/2" rear lift block and u-bolts to help level the stance of the vehicles. Rear shock options include Performance twin tube or Stealth monotube shocks for increase dampening.

This system offers a mild lift height with increased wheel travel for aggressive offroad driving. The stock upper control arms are replaced with high quality tubular Uniball arms that allow unrestricted movement throughout the travel range.
