The "Strong" 6" suspension lift kit for the Avalanche, Silverado and Sierra uses extended steering knuckles and a 3-piece sub-frame that includes 2 crossmembers that are conneted by a heavy duty skid plate that's been designed to protect the front differential and stabilize the crossmembers for unmatched strength and durability. Easier to install than the 1-piece lift kit. For the rear, 4" cast iron blocks are included. Differential drop brackets and torsion bar drop brackets keep everything in alignment. Also included are lateral compression arms which, along with the 3-piece sub frame, strengthen and stabilize the front end. Four SX6000 Hydro shocks are included. Shock boots sold separately.
