The QA1 Pro Coil lowering kit is an all-in-one suspension upgrade for the 2007-2018 Silverado 1500 and Sierra 1500. It pairs QA1 front Pro Coil coil-overs with a rear drop kit for a dialed-in lowered stance along with improved ride quality and handling. Fully threaded front coil-over bodies set ride height without shims or spacers, and the rear drop hardware fine-tunes the final rake. The heavy-duty Pro Coil shock uses polyurethane bushings and a 1 in. chromoly T-bar to handle the weight and payload of a modern truck. Every component is engineered for a hassle-free, fully bolt-in installation.
