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 other spring rate options are also available and have been successfully tested in various applications, from casual street driving to hard core race applications.
