QA1 GM Pro Front Coil-Over System Double Adjustable 10in 400lbs/in Aluminum Select 1968-1972 GM A-Body
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1968-1972 Buick Skylark/Special, Chevrolet Chevelle/El Camino, GMC Sprint, Oldsmobile 442/Cutlass/Vista Cruiser, and Pontiac GTO/LeMans/Tempest.
The QA1 GM Pro Coil System is a bolt-in suspension upgrade engineered to provide independent control over both rebound and compression valving. Designed for the GM A-Body platform, this system features double-adjustable billet aluminum shocks with a fully threaded body, allowing for precise ride height adjustments up to 2 inches. This enables you to dial in a perfect stance while optimizing weight balance for improved cornering and handling.
This kit includes QA1’s American-made high travel springs (10-inch length, 400 lbs/in rate). These lightweight springs are manufactured with fewer coils and a smaller wire diameter than traditional springs, reducing unsprung weight and providing more suspension travel. Whether you are setting up a car for street performance, autocross, or drag racing, this system offers the tunability needed for diverse driving environments. Each shock is 100% dyno tested and serialized to ensure consistent performance out of the box.
