Product Details
Description
The Tuff Country 14045KN 4" Lift Kit with Knuckles and 3-Piece Sub-Frame and SX8000 Shocks is a bolt-on suspension upgrade designed for 2004–2012 Chevy Colorado and GMC Canyon 4WD pickups. It delivers a capable lift, improved ground clearance, and a more aggressive stance without a complicated install.
- Lift Height: 4" front and 3" rear lift tailored for 2004–2012 Chevy Colorado 4WD and GMC Canyon 4WD.
- Knuckles & Sub-Frame: includes new knuckles that eliminate the need to drop upper control arms and a robust 3-piece sub-frame for a solid, aligned foundation.
- Shocks Included: SX8000 shocks are included to balance control and comfort on and off the pavement.
- Protection: skid plate protects the differential and helps stabilize cross members for rugged terrain.
- Wheel Geometry: torsion bar remains in stock location to preserve steering feel and ride characteristics.
- Tire Compatibility: enables the use of 31 x 10.50 tires for added traction and a more commanding look.
- Installation: designed for a straightforward bolt-on installation with the necessary hardware included.
- Warranty: backed by a limited lifetime warranty for lasting confidence in your investment.
- Made in the USA: manufactured in the United States, reflecting Tuff Country’s long-standing engineering heritage.
- Wheel/Rim Considerations: factory rims will not fit; requires rims with 4.5" back spacing or less and will not fit 15" rims.
This lift kit is ideal for enthusiasts who want to broaden their Colorado or Canyon’s capabilities—whether you’re hitting gravel roads, muddy trails, or paved roads with a more assertive stance. The combination of knuckles, a sturdy sub-frame, and SX8000 shocks delivers improved approach angles, better ground clearance, and confident handling across terrain, while the simple bolt-on design keeps installation accessible. Pair it with appropriate extended shocks as instructed and you’ll enjoy a balanced, reliable upgrade that stands up to daily driving and weekend adventures alike.
