Product Details
Description
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.
The kit is engineered to deliver real-world benefits: higher ground clearance to tackle trails and uneven terrain, the ability to fit larger tires without sacrificing handling, and a firmer ride thanks to the reinforced sub-frame. The included knuckles and one-piece sub-frame reduce potential rattles and misalignment, preserving steering precision as you navigate dirt roads or paved streets. Designed specifically for 1999–2005 Silverado 1500 4WD and GMC Sierra 1500 4WD, this lift kit helps you achieve a confident, capable build that stands up to daily use and weekend adventures alike.
