Quick Overview

Extended steering knuckles and a one-piece sub-frame are the key to this 6" Tuff Country lift kit for the Chevy Silverado, GMC Sierra 3500HD. 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. Longer shocks are required and sold separately.
