Compressed length of 10.13\" and extended length of 17\". Includes 10\" spring with rating of 400 and has a large tapered flat end.\nThese 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.

This single-adjustable, stock-mount system includes a 10-inch, 400 lb\/in spring with a large tapered flat end and is engineered for a proper fit on select 1977–1981 Pontiac Firebird applications. The shock features a compressed length of 10.13 inches and an extended length of 17 inches, providing useful suspension travel for street performance, autocross, road racing, drag racing, and street rod applications.\u003cbr\u003eThe fully threaded shock body allows precise ride-height adjustment for stance, corner-weight tuning, and improved handling balance. QA1’s high-travel springs use fewer coils and a smaller wire diameter to increase the space between coils, helping provide greater available travel while reducing unsprung weight. The adjustable valving lets you tailor the suspension response to match your driving style, spring rate, tires, and vehicle setup. This design is intended to help improve suspension control without requiring a complicated installation.\u003cbr\u003eThe QA1 Pro Coil system is engineered for easy bolt-in installation and is made in the USA. QA1 shocks are fully dyno tested and built to be serviceable and rebuildable through authorized QA1 service centers, supporting long-term performance and maintenance. The lightweight aluminum coil-over shock design and adjustable ride height make this system a practical upgrade for performance-focused builds seeking more control than a conventional fixed suspension setup. This product is sold as a pair and is backed by QA1’s best-in-class warranty. Professional installation and alignment are recommended after installation and ride-height
