The Tuff Country 2‑inch lift kit for 1999–2006 GMC Sierra 1500 4x4 includes front replacement torsion bar keys, rear lift blocks and extended u‑bolts to lift the truck two inches. The torsion keys reindex factory bars to raise the front without cranking, while lift blocks and extended u‑bolts increase rear height. The kit ships with required hardware and preserves the factory rake for balanced stance.
