QA1 high travel coil-over springs are wound from specially designed high-tensile chrome silicon alloy spring wire, which allows fewer coils and a smaller wire diameter. The result is a lighter spring with increased travel from the larger gap between coils, reducing unsprung weight and reacting faster for improved suspension response. Careful heat-treating and post-processing extend fatigue life, and the coil design lets the spring compress to coil-bind without affecting spring rate or free height. This spring is ground at both ends for straight, consistent operation, finished in silver powder coat, and made in the USA. All QA1 springs carry a lifetime guarantee to remain within 2% of the original free height and rate under normal operating conditions.

FAQ
What is the inside diameter of this QA1 high travel spring?
This spring has a 2-1/2in (2.5in) inside diameter, sized for QA1 coil-over shocks and other coil-over systems that use standard 2.5in ID springs.
What are this spring's free length and rate?
It has a 14in free length and a 250 lbs/in spring rate.
What makes QA1 high travel springs lighter than standard springs?
They are wound from high-tensile chrome silicon alloy spring wire, which uses fewer coils and a smaller wire diameter to cut weight and increase travel while reducing unsprung mass.
Are QA1 springs guaranteed?
Yes. QA1 springs are lifetime guaranteed to remain within 2% of their original free height and rate under normal operating conditions.
