The Tuff Country 5" lift kit includes front strut spacers, replacement heavy duty steering knuckles that eliminate the need for ball joint spacers. Upper ball joints and bearing are pressed into the new knuckles. Upper strut spacers are used to lift the front so replacement struts are not required. Also included are one piece sub frame, front differential barckets, front sway bar drop brackets, steering shaft extension and a rear cast iron block kit. Rear SX6000 Hydro shocks are included. Shock boots sold separately. This kit is designed to fit with ABS brakes and automatic hubs. Vehicles without ABS brakes require optional ABS plugs 54900-13.
