The Fabtech 6" Performance System with Performance Shocks is the prefect kit for daily driving and/or off-road use. This is achieved by Fabtech's one piece arched Lower Control Arm Crossmembers and extended length steering knuckles. The 1/4" thick arched Lower Control Arm Crossmembers include a Front Differential Skid Plate, Crossmember support tubes and rear impact struts.
