Product Details
Description
Elevate your Silverado 1500 or Sierra 1500 4WD with the Tuff Country 12031KN 2" EZ-Install Lift Kit. Built for reliability and value, this kit provides a straightforward lift with a balanced stance and confident road manners.
- 2" Front & 2" Rear Lift: Adds height evenly for improved ground clearance and a refreshed, proportionate look without altering overall geometry.
- EZ-Install Design: Includes lower-mount spacers for a simpler, quicker installation; in most cases front struts do not need replacement.
- Rear Lift Blocks: Replaces factory blocks with 3" rear blocks to preserve the factory rake while adding height.
- U-Bolts & Hardware Included: Complete mounting kit with all required components for a secure, factory-quality fit.
- SX8000 Shocks Included: Premium shocks paired with the kit to improve ride quality and handling after the lift.
- Made in the USA: Support for U.S. manufacturing standards and quality craftsmanship.
- Limited Lifetime Warranty: Tuff Country backs this lift kit with a lifetime warranty for lasting peace of mind.
- Fitment & tire guidance: Compatible with 2007–2018 Silverado 1500 4WD and 2007–2018 GMC Sierra 1500 4WD; not compatible with Magnetic Ride Control or Air Suspension; 32"x10.5" tires recommended with aftermarket rims; if using factory rims, no trimming is required; aftermarket rims may require positive 30 offset and possibly trimming depending on offset.
This kit is designed for real-world use: it adds a practical 2" of lift to both ends while maintaining the factory rake, so your truck looks purpose-built without an aggressive stance. The SX8000 shocks help absorb bumps on daily drives and light off-road trails, providing steadier handling and a more controlled ride. Installation is streamlined to save time, and the included hardware ensures a solid, durable mount. With the lifetime warranty and Tuff Country’s 35+ years of suspension experience, you get a proven upgrade you can trust for many miles to come.
