Rancho 2007-2013 Silverado & Sierra 4" Lift Kit # RS6583B

This Rancho suspension system (Part No. RS6583B) supercedes the older RS6563B Kit. Rancho has designed their suspension lift to accommodates up to 315/70/17 tires. And more good news, this Rancho Suspension Lift System can enhance the new Silverado and Sierra 1500 coil-over independent front suspension design by replacing the factory coil-overs with Rancho RS9000XL performance shock absorbers. The Rancho RS9000XL shocks are designed to deliver enhanced ride and handling both on and off the pavement. And if you like your factory wheels we have good news for you, the Rancho RS6583B system also is compatible with stock tire/wheel packages.

The Rancho Chevy Silverado 1500 and GMC Sierra 1500 2wd & 4WD suspension system features a variety of exclusive design and construction elements to ensure maximum performance and unmatched durability, including Rancho's legendary one-piece sub-frame. The sub-frame provides a precision-matched fit and superior strength through its laser-cut 1/4" thick steel construction. To provide extra strength during off-road use, Rancho includes high-clearance aft braces to maximize ground clearance. Plus, every Rancho Silverado/Sierra system maintains OE-quality steering precision by maintaining the factory's rack and pinion location, making it faster and easier to install. As with any Rancho system, the latest Silverado/Sierra lift kit includes detailed and illustrated instructions. No drivetrain or exhaust modifications are necessary. Preserving original equipment geometry for minimal bump steer, the new system also includes extended cast steering knuckles. Another key feature are front differential drop brackets that correct pinion angle and minimize driveline vibration. Each new suspension includes new, extended-length, DOT-certified front brake lines.
