Designed for 2006 GM Silverado/Sierra 1500 4WD trucks equipped with factory air‑ride shocks, this kit balances rugged capability with practical, user‑friendly installation. Its knuckle and sub-frame design improve steering feel and chassis stiffness, while the one-piece sub-frame minimizes flex for a more predictable ride. Pair it with extended shocks and the right wheels, and you gain substantial ground clearance, a bold stance, and improved off‑road traction with 36" tires—without sacrificing daily drivability. Note the installation considerations to ensure a successful fit and long‑term performance.
