Description
Excellent Off-Road Performance and On-Road Comfort. Transform your daily driver Silverado into an off-road warrior with the SuperLift 6-Inch Knuckle Suspension Lift Kit with Billstein Shocks. This suspension lift kit comes with components designed to provide enhance your truck’s ground clearance while keeping its ride quality at near factory levels. Specifically, this kit adds 6 inches of front and rear lift, while leveling out your stance for a bold look. This added clearance also enables you to install up to 35-inch wide tires, completing that off-road look you’ve always wanted.
Performance-Oriented Billstein Front and Rear Shocks. This suspension lift kit includes a set of front and rear Billstein shock absorbers. These performance-oriented shocks feature a monotube, gas-charged design to offer more precise damping performance. The result is a more responsive steering feel and handling. Moreover, these shocks’ nickel-plated and clear coated steel body offers maximum corrosion resistance and long service life.
Heavy-Duty Iron Steering Knuckles. The 6 inches of front lift is provided by a pair of lifted steering knuckles. These knuckles are designed to retain factory steering angles, maintaining OE alignment and steering feel. In addition, these knuckles feature a precision-machined ductile iron construction, providing maximum strength and an exact fit when mounted.
High-Strength Alloy Lift Blocks. Lifting the rear is made possible by a pair of high-strength iron lift blocks. These lift blocks are manufactured using a specialized casting process resulting in components that fit precisely onto your leaf springs. Additionally, these lift blocks are treated with an anti-corrosion coating extending their service life.
Durable Steel Anti-Sway Bar Links. Another set of components that ensure factory handling and ride comfort is maintained is a pair of longer front anti-sway bar links. These anti-sway bar links ensure correct steering geometry is maintained, so your truck handles at near OE levels. Also, these links are constructed from durable steel for extreme strength.
Professional Installation Recommended. This lift kit will require welding, cutting, and drilling to properly install certain components. You will also need a full set of tools and advanced mechanical knowledge. As such, professional installation is recommended.
Features a Limited Lifetime Warranty. This SuperLift suspension lift kit features a limited lifetime warranty covering workmanship and material defects. Please visit the manufacturer’s website for more details.
