QA1 GM Pro Front Coil-Over System - Single Adj. - 11in x 250lb/in - Pigtail - Aluminum - Select GM 1967-1974 GS401-11250A
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 provides a bolt-in solution for drivers seeking precise ride height adjustment and valving control. These systems feature lightweight billet aluminum shocks with a single adjustment knob that simultaneously controls compression and rebound, allowing you to quickly tune your suspension for street performance, autocross, or drag racing. The included American-made high-travel springs are engineered with fewer coils and a smaller wire diameter to reduce unsprung weight and increase suspension travel compared to standard springs.
- Billet aluminum threaded shock bodies for easy ride height tuning
- Single adjustable valving (simultaneous compression and rebound)
- 11-inch high-travel springs with a 250 lbs/in spring rate
- Pigtail spring design for compatible factory-style mounting
- 100% dyno tested and serialized for quality assurance
- Fully serviceable and rebuildable design
- Includes all necessary hardware for a pair of front shocks
- Made in the USA
- Manufacturer Part Number: GS401-11250A
