High Travel Options

Springs with HT in the part number are high travel springs. Made in the USA, the 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.

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.

Lifetime Guarantee

All QA1 springs are lifetime guaranteed to remain within 2% of the original free height and rate under normal operating conditions.
