These high travel springs, silver powder coated, are designed to fit with QA1's Pro Coil Systems for 4th Generation F-Body.
Featuring a 2.125" upper I.D.
and 2.5" lower I.D., these springs are made in the USA.
With fewer coils and a smaller wire diameter, they are lighter and have increased travel due to the larger distance between the coils.
These lighter springs reduce unsprung weight and react faster, optimizing suspension performance.
The high-grade material, along with careful heat-treating and post-processing, allows for greatly improved fatigue life, and the coil design permits compression to coil-bind without affecting spring rate or free height.
All QA1 springs are manufactured using the highest quality materials for high strength, consistency, and long life.
They are cold wound, heat treated, and shot peened to ensure consistency, accuracy, and durability.
All QA1 springs are ground at both ends to ensure straight, consistent, and accurate operation.
They are either silver powder coated for excellent longevity or polished and chrome plated for the ultimate in appearance.
Lengths and rates are clearly marked for quick and easy identification.
All QA1 springs are lifetime guaranteed to remain within 2% of the original free height and rate under normal operating conditions.
