The QA1 GM Pro Front Coil-Over System provides a comprehensive suspension upgrade for enthusiasts demanding precision ride height and damping control. This double-adjustable system features independent knobs for compression and rebound, allowing you to fine-tune the suspension for specific driving conditions, from street cruising to competitive track use. The billet aluminum shock bodies are fully threaded, providing up to 2 inches of ride height adjustment to help you achieve the perfect stance and weight balance.

This kit includes QA1 High Travel springs, manufactured in the USA from lightweight wire with fewer coils than traditional springs. This design reduces unsprung weight and increases suspension travel by providing more room between coils. Designed as a direct bolt-in solution, these coil-overs install easily into factory mounting points and are compatible with both OE and QA1 tubular control arms.
