    Details

    These silver powder, high travel springs are made to fit with QA1's 4th Generation F-Body Pro Coil Systems. With a 2.125" upper I.D. and 2.5" lower I.D., they are offered in 3 rates with a 15" free length.

    Made in the USA, these high travel springs have fewer coils and a smaller wire diameter. As a result, 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.

    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.

    Chrome Silicon Steel (CrS)

    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.

    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.
