The Tuff Country 2‑inch lift kit for 2001–2010 Silverado 2500HD (non‑Purple TB) uses front torsion bar keys and rear lift blocks to raise the truck while keeping the factory rake. Replacement torsion keys reindex the factory 2500HD torsion bars to lift the front without overstressing them. The kit includes lift blocks, extended u‑bolts and hardware for a complete two‑inch lift installation.
