Description

The new Rancho 4.5-inch performance suspension system enhances the ride and appearance of the popular truck models, including 2017-14 Chevrolet Silverado/GMC Sierra 1500s. The kits are available in two configurations to match OE upper control arm materials, including Rancho engineered and fabricated steel upper control arm (RS66308B) or aluminum or stamped steel upper control arm (RS66309B). Each kit includes Rancho’s fully welded subframe for superior strength and ductile iron steering knuckles. Designed for a fast and easy installation, the Rancho engineering team maintained the factory’s rack and pinion location for OE-quality steering characteristics and minimized bump steer by maintaining OE geometry overall. Each kit includes a pair of CV spacers, brake line brackets, sway bar relocation brackets, rear tapered block, u-bolts and other required hardware. To make installation easier and faster, Rancho engineers provide a thorough, full-color step-by-step guide for the new Silverado/Sierra system. The new Rancho Silverado/Sierra 4.5-in. performance suspension system is compatible with any of Rancho’s performance shock series, including RS5000™X, RS7000®MT and RS9000™XL shocks. The Rancho brand carries an industry leading Performance Guarantee and 90-day risk-free ride offer that lets enthusiasts try RS9000XL, RS7000MT or Rancho RS5000X shocks for any truck or SUV for 90 days. Consumers can return their shocks within 90 days for a full refund of the product’s purchase price. For a complete list of applications covered by the warranty, please visit www.GoRancho.com.
