The Tuff Country 6" lift kit for the Chevy Silverado, GMC Sierra 3500HD features extended steering knuckles and a multi-piece sub frame as the foundation of this lift. Knuckles keep the vehicle in alignment and eliminate the need to drop the upper control arms. The 3-piece sub frame makes installation simple with 2 crossmembers and a heavy duty skid plate. Also included is a torsion bar crossmember skid plate for added undercarriage protection. Differential drop brackets and torsion bar drop brackets maintain alignment. Rear brake line relocation brackets included. All front bump stops are relocated to maintain factory specs. The rear is lifted using a 4" cast iron block kit. Four SX6000 Hydro shocks included. Shock boots sold separately.
