The Tuff Country 2‑inch lift kit for 2001–2010 Silverado 2500HD uses front replacement torsion bar keys and rear add‑a‑leaf springs to raise the truck while preserving factory rake. The torsion keys reindex the stock 2500HD torsion bars to lift the front without overstressing them. This kit includes the hardware needed for installation and provides a practical two‑inch lift for improved clearance.
