Rancho suspension system

Rancho Performance Suspension System has added new products for 2017 models of Chevrolet Silverado and GMC Sierra 1500 trucks. The Rancho 4.5-inch performance suspension system was engineered to accommodate different upper control arm materials used by the two truck models. Two configurations are available, both configured to match original equipment materials: the Rancho engineered and fabricated steel upper control arm (RS66308B) or aluminum or stamped steel upper control arm (RS66309B). The kits also include a pair of CV spacers, brake line brackets, sway bar relocation brackets, rear tapered block, u-bolts and other required hardware, plus a full-color step-by-step guide.
