QA1 GM Pro Front Coil-Over System for 1963-1982 Chevrolet Corvette, Single Adjustable, 9in x 650lbs/in, Pigtail Large

Fits 1963-1982 Chevrolet Corvette models (Base, Collector's Edition, Indianapolis 500 Pace Car, Silver Anniversary Edition, and Stingray).

The QA1 GM Pro Front Coil-Over System provides a direct bolt-in solution to modernize the front suspension of your C2 or C3 Corvette. This single-adjustable system features a single knob that simultaneously adjusts compression and rebound valving, allowing you to dial in the perfect ride quality for street performance or track use. The lightweight billet aluminum shock bodies are fully threaded, enabling up to 2 inches of ride height adjustment to achieve a specific stance or to fine-tune weight balance.

This kit includes American-made high-travel springs, specifically engineered with a smaller wire diameter and fewer coils to reduce unsprung weight and react faster to road surfaces. Each shock is 100% dyno-tested and serialized to ensure precision performance. Whether you are running factory control arms or upgraded QA1 tubular arms, this system integrates seamlessly into your existing setup.
