The Fabtech ductile iron steering knuckles retain the stock track width keeping the tires under the fender for a clean appearance. Rear lift is accomplished with a block and u bolt configuration. The Basic System includes heavy duty front Coilover shocks for increased dampening capacity while retaining the factory coil springs. Rear shocks include Fabtech's Performance or Stealth shocks. 4in.
