They are a great option for adjustable ride height and valving control.
Choose a spring rate and adjustability that fits your driving style, and adjust the valving to match.
These shocks utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely calibrate the weight balance for superior handling.
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.
