QA1 GM Pro Front Coil-Over System, Single Adj, 10in 500lb/in Pigtail, 1967-1974 GM F/X-Body (GS401-10500A)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1967-1974 Buick Apollo, Chevrolet Camaro, Chevy II, Nova, Oldsmobile Omega, and Pontiac Firebird and Ventura.
The QA1 GM Pro Coil System is engineered for drivers who demand precision ride height control and adjustable valving in a bolt-in package. This system replaces the factory front shock and spring with a high-performance coil-over conversion, featuring a single-adjustable knob that simultaneously tunes compression and rebound damping. Whether you are setting up for street performance, autocross, or drag racing, the fully threaded billet aluminum body allows you to dial in the perfect stance and optimize corner weights for superior handling.
This kit includes QA1 high-travel springs, manufactured in the USA from lightweight wire with fewer coils than standard springs. This design reduces unsprung weight and increases suspension travel by maximizing the distance between coils. Each shock is 100% dyno tested and serialized to ensure consistent performance right out of the box.
