The "Strong" 4" suspension lift kit for the Chevy Silverado, GMC Sierra 3500HD uses extended steering knuckles and a 3-piece sub-frame that includes 2 crossmembers that are connected by a heavy duty skid plate that was 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. Longer shocks are required and sold separately.
