Description
Improved Off-Road Performance and Ride Comfort. Improve your off-road performance while maintaining a factory ride comfort with the SuperLift 6-Inch Knuckle Suspension Lift Kit with SuperLift Shocks. This suspension lift kit offers 6 inches of overall lift, increasing ground clearance and leveling out your stance. This added lift allows you to navigate more uneven off-road trails on 35-inch wide tires. Best of all, this lift kit accomplishes this while keeping your Silverado’s ride quality at near factory levels of comfort.
High-Quality SuperLift Front and Rear Shocks. This suspension lift kit replaces all your factory shocks with front and rear SuperLift shock absorbers. These shocks combine a twin-tube configuration with 10-stage velocity sensitive valving technology. This setup offers improved damping performance that’s tuned to the terrain you’re on. This translates to more sensitive damping on the trails and a smooth ride on the highway.
Sturdy Iron Steering Knuckles. Providing front lift is a pair of lifted steering knuckles. These knuckles are configured to prevent binding, thus maintaining OE alignment. Additionally, these steering knuckles are precision-machined from ductile iron ensuring an accurate fit when installed.
Wear-Resistant Alloy Lift Blocks. Rear lift is provided by a pair of wear-resistant lift blocks. These lift blocks are cast from high-grade iron before being finished to precise specifications. This provides a precise fit when installed as well as exceptional durability.
Brawny Steel Anti-Sway Bar Links. This lift kit also includes a pair of longer anti-sway bar links for the front. These links are designed to maintain steering geometry, ensuring your Silverado’s handling remains at near OE levels. These components are manufactured from high-grade steel providing maximum strength and long-lasting performance.
Professional Installation Recommended. Installing this lift kit will require welding, cutting, and drilling. You will also need a full set of tools and extensive mechanical knowledge. If you do not have any experience welding, professional installation is recommended.
Includes a Limited Lifetime Warranty. This SuperLift suspension lift kit includes a limited lifetime warranty against workmanship and material defects. Please visit the manufacturer’s website for more details.
Application. The SuperLift 6-Inch Suspension Lift Kit with SuperLift Shocks fits all 1999 to 2006 4WD Chevrolet Silverado 1500 models.
