QA1's Mustang II Front Pro Coil System is a bolt-in coil-over conversion built for ride quality on the street and strip. The fully threaded shock body sets a lower ride height and dials in the desired stance while helping balance the chassis, and the single adjustable aluminum shocks tune the ride to match driving style. The system includes two QA1 performance shocks, two specially designed springs and all mounting hardware. It is 100 percent dyno tested and serialized, rebuildable and revalveable by QA1 or its authorized service centers, made in the USA and sold in pairs.
