Extended steering knuckles and a one-piece sub-frame are the key to this 6" Tuff Country lift kit for the Avalanche, Silverado and Sierra. 2" cast iron blocks lift the rear to level the vehicle. Differential drop brackets and torsion bar drop brackets keep everything in alignment. A 1-piece sub-frame strengthens and stabilizes the front end. Also included are lateral compression arms which, along with the 1-piece sub frame, strengthen and stabilize the front end. Four SX8000 Nitro shocks are included. Shock boots sold separately.
