These springs fit perfectly with QA1’s Pro Coil Shock Systems and are available with pigtail ends in 10” free lengths.
QA1 springs are made with the highest quality materials, ensuring strength, consistency, and a long life.
Chrome Silicon Steel (CrS) is used in all QA1 springs, which are manufactured for high strength, consistency, and long life.
All QA1 springs undergo intensive manufacturing processes for consistency, accuracy, and durability.
QA1's GM Pro Coil springs feature a silver powder coating for excellent longevity.
Springs with HT in the part number are high travel springs.
Made in the USA, these high travel springs have fewer coils and a smaller wire diameter, resulting in lighter weight and increased travel due to the larger distance between the coils.
These lighter springs reduce unsprung weight and react faster, optimizing suspension performance.
All QA1 springs are clearly marked with the free length and spring rate for quick identification.
All QA1 springs come with a lifetime guarantee to remain within 2% of the original free height and rate under normal operating conditions.
