Front Pro Coil single adjustable stock mount shock kit. Compressed length of 10.13" and extended length of 17". Includes 10" spring with rating of 550 and has a large tapered flat end. These QA1 GM Pro Coil Systems are a great option for anyone looking for fully adjustable ride height and valving control. Choose a spring rate and adjustability that fits your driving style, adjust the valving to match and you are on your way. These shocks also utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely tune the weight balance for superior handling. Specially designed for QA1's Pro Coil Systems, the American-made lightweight high travel springs have fewer coils and a smaller wire diameter, resulting in increased travel due to the larger distance between the coils. They reduce unsprung weight and react faster, optimizing suspension performance. Multiple spring rate options are also available and have been successfully tested in various applications, from casual street driving to hard core race applications.

Upgrade the front suspension of your classic Pontiac with the QA1 qapGS501-10550C GM Pro Front Coil-Over System. Designed for stock-mount applications, this single-adjustable kit combines ride-height adjustability with tunable shock valving to help improve handling, stance, and overall suspension response. It fits select 1977–1981 Pontiac Firebird models and includes a 10-inch, 550 lb/in high-travel spring with a large tapered flat end.
The QA1 Pro Coil System uses a fully threaded shock body for precise ride-height adjustment, allowing you to achieve the desired stance or fine-tune vehicle weight balance. Adjustable valving lets you tailor suspension performance to your driving style, whether the vehicle is used for street performance, autocross, road racing, drag racing, or street rod applications. The lightweight high-travel spring design uses fewer coils and a smaller wire diameter to increase available travel, reduce unsprung weight, and promote faster suspension response.
This American-made QA1 system is engineered for easy bolt-in installation and dependable performance. Pro Coil shocks are dyno tested and serialized, and serviceable, rebuildable support is available through QA1 authorized service centers. The kit is sold in pairs and is designed specifically for GM applications requiring a front single-adjustable coil-over setup.
