Long Beach, Calif. – Engineered to accommodate the different upper control arm materials being used by Chevrolet and GMC, 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.
