14955KN BOX 1 OF 4

Upgrade your 1999–2005 Chevy Silverado 1500 4WD or GMC Sierra 1500 4WD with the Tuff Country 14955KN 4" Lift Kit. This complete package combines knuckles, a one-piece sub-frame, and SX8000 shocks to deliver improved ground clearance, stronger chassis feel, and a bold, capable stance—without complicated fabrication. Lift Height: 4" front and 4" rear lift to increase ground clearance and accommodate larger tires. Includes Shocks: SX8000 shocks are included for a balanced, controlled ride right out of the box. Knuckles: New steering knuckles designed to eliminate the need to drop upper control arms during installation. One-Piece Sub-Frame: Adds overall strength and helps reduce squeaks and rattles for a steadier feel on rough roads. Tire Compatibility: Ready to run with 33" x 12.5" tires for enhanced traction and a more aggressive look. Installation Notes: Simple bolt-on installation. Factory length shocks must be replaced with extended shocks to install properly. Wheel rims must have a 4.5" offset or less; factory rims may not fit. Warranty & Support: Backed by Tuff Country’s limited lifetime warranty and supported by a leading retailer with expert knowledge.
