Return PolicyThese QA1 GM Pro Coil Systems are available for 1978-1996 GM B-Bodies, 1988-1998 Chevy/GMC C1500s, 1971-1996 Impalas and Full-Size GM vehicles, including Full-Size Chevy, Buick, Oldsmobile, and Pontiac models, and 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.
