The Tuff Country 16958 6" Lift Kit with Knuckles and a 1-Piece Sub-Frame is a bolt-on suspension upgrade designed for 2001–2006 Chevy Silverado 1500HD 4WD and GMC Sierra 1500HD 4WD, with 2001–2004 Chevy Avalanche 2500 4WD compatibility. It delivers a bold, capable stance and room for up to 35" tires, combining rugged engineering with straightforward installation.

The bolt-on installation simplifies what can otherwise be a complex upgrade, helping you complete the project in a single weekend. With this lift, you can confidently tackle dirt roads, gravel trails, and everyday driving while enjoying the rugged presence of a lifted Silverado/Sierra. Remember to plan for extended shocks and aftermarket rims to ensure proper fitment and performance, backed by Tuff Country’s 25+ years of suspension expertise and a lifetime warranty.
