The QA1 GM Pro Coil front coil-over kit pairs a lightweight single-adjustable billet aluminum coil-over shock with a high travel coil spring for adjustable ride height and valving control. The fully threaded shock body allows ride height to be set for the desired stance and the corner weights to be fine-tuned, while the single-adjustable valving lets the shock be tuned from a comfortable street setting to firmer performance damping. QA1's American-made high travel springs use fewer coils and a smaller wire diameter to reduce unsprung weight for faster response. The shocks bolt in using the stock mounts, are 100 percent dyno tested and serialized, and are serviceable and rebuildable through QA1 authorized service centers. Sold in pairs.
