Made in the USA, these 2-1/4" I.D. springs are a light-weight, high travel spring design with a black powder coated finish. These springs 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. In addition, this high-grade material, along with careful heat-treating and post-processing, allows for greatly improved fatigue life, and the coil design allows the springs to be compressed to coil-bind without affecting spring rate or free height. These new high travel springs are silver powder coated and ground at both ends for straight, consistent and accurate operations. In addition, all QA1 springs are lifetime guaranteed to remain within 2% of the original free height and rate under normal operating conditions. Chrome Silicon Steel All QA1 springs are manufactured using the highest quality materials for high strength, consistency and long life. Cold Wound - Heat Treated - Shot Peened All QA1 springs go through intensive manufacturing processes to ensure consistency, accuracy and durability. Squared Ends All QA1 springs are ground at both ends to ensure straight, consistent and accurate operation. Lengths and Rates Marked All QA1 springs are clearly marked with the free length of the spring and spring rate for quick and easy identification. Made in the USA QA1's high travel springs are proudly made in the USA. LIFETIME GUARANTEE All QA1 springs are lifetime guaranteed to remain within 2% of the original free height and rate under normal operating conditions.
Fitment Note: Fit limited applications requiring 2-1/4" springs which will not fit most QA1 coil-over shocks. Limited fit to specific QA1 C5/C6 coil-over kits.
