The totally re-engineered Silverado / Sierra Pickup incorporates a new coil-over independent front suspension design. Rancho's exclusive RS9000X™ replacement front coil-over shock absorber eliminates the need to use spacers. This uncompromising design provides enhanced off-road performance and untouchable ride quality. Underneath the front end of the vehicle is Rancho's signature "one-piece sub-frame." Constructed from laser-cut ¼-inch thick steel, the sub-frame's components are welded to provide a precise fit and superior strength. Steering integrity is uncompromised by maintaining the stock location of the factory rack and pinion steering. This, along with new extended cast steering knuckles, maintains optimal steering geometry. All of these legendary Rancho® features result in a time-saving, less complex installation, and allows for the reuse of the stock wheels. The new system fits up to a 315/70/17 tire*.
