Product Details
Description
Upgrade your Chevy Silverado 1500 or GMC Sierra 1500 4WD with the Tuff Country 14066KN 4" Uni-Ball Lift Kit. This all-in-one system is designed for drivers who want solid off-road capability without sacrificing everyday handling, and it comes with upper control arms, rear blocks, U-bolts, and SX8000 shocks for a complete, ready-to-install package.
- Lift Height: 4" front lift and 2" rear lift to improve ground clearance and accommodate larger tires.
- Upper Control Arms: Uni-Ball upper control arms replace OE arms to enhance articulation and reduce binding when the suspension flexes off-road.
- Shocks Included: SX8000 shocks are included for tuned damping and a smoother, more controlled ride across varied terrain.
- Rear Components: Rear blocks and U-bolts provide secure axle positioning and stability with the lifted stance.
- No Drilling Required: Designed for straightforward installation without drilling; factory rims require 4.5" backspacing or less.
- Rim Backspacing Requirement: Factory rims will not fit with this lift kit; use rims with 4.5" backspacing or less for proper fitment.
- Vehicle Compatibility: Specifically engineered for 2007–2013 Chevy Silverado 1500 4WD and 2007–2013 GMC Sierra 1500 4WD with one-piece OE cast steel upper arms. Not compatible with Magnetic Ride Control or Air Suspension.
- Tire Fit: Enables the use of 33" x 12.5" tires for a bold, capable look and enhanced off-road traction.
- Made in the USA: Proudly manufactured in the United States with a focus on quality and durability.
- Warranty: Backed by a limited lifetime warranty for long-term peace of mind.
The Tuff Country 14066KN lift kit is engineered to preserve a near factory ride while dramatically improving ground clearance and tire flexibility. With Uni-Ball upper control arms, you’ll notice improved steering response and better axle articulation as you tackle uneven terrain. The SX8000 shocks balance handling and comfort, so daily driving remains confident even with the larger tire setup. This kit is ideal for truck owners who want a capable, reliable lift that supports 33" tires and maintains a durable, USA-made standard backed by a lifetime warranty.
