QA1 GD501-10600C GM Pro-Coil Double Adjustable Front Coilover Kit 10in. 600 lb/in. Aluminum

The QA1 GD501-10600C is a front Pro-Coil double adjustable coilover shock system designed for GM muscle cars and performance vehicles. This bolt-in kit delivers fully independent compression and rebound tuning for drivers who demand precise suspension control whether on the street or at the track.

Double Adjustable Valving: Independent tuning of compression and rebound allows you to fine-tune the handling or straight-line performance of your vehicle for any driving condition. The 18-position adjustment knob is conveniently accessible by turning the steering wheel to full lock, so adjustments can be made at the base of the shock without removing wheels or tools.

Ride Height Adjustability: The fully threaded aluminum shock body provides 0 to –2 inches of ride height adjustability, allowing you to dial in the perfect stance. Adjustments are made with a simple turn of the spring seat nut. For drops beyond 2 inches, drop spindles can be added.

USA-Made High-Travel Springs: This kit includes 10-inch, 600 lb/in. tapered flat large-diameter springs specially engineered for QA1's Pro-Coil system. These American-made springs feature fewer coils and a smaller wire diameter, resulting in increased travel and reduced unsprung weight for faster suspension response.
