Description

QA1 designed these GS401-10400C Pro Coil System Front Single Adjustable coilover shocks for the GM 1975-79 X-Body. They are a great option for anyone looking for fully adjustable ride height as well as valving control. These shocks have a fully threaded body that allows ride height adjustment for the perfect stance or 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. This results 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.
