The QA1 qap9HT450B High Travel Coil Spring is engineered for suspension applications that demand reduced unsprung weight, increased travel, and responsive performance. With a 450 lb/in spring rate, a 2-1/2-inch inner diameter, and a 9-inch free length, this spring provides reliable support for performance-oriented automotive suspension systems. Its black powder-coated finish helps protect the spring from everyday wear while providing a clean, durable appearance.
Manufactured from specially designed high-tensile chrome silicon alloy spring wire, this QA1 high travel spring uses fewer coils and a smaller wire diameter than conventional springs. The resulting lightweight construction increases the distance between coils, allowing greater suspension travel while helping the spring react faster. Reduced unsprung weight can improve suspension response and contribute to more consistent handling on the street, track, or other demanding applications.
The QA1 qap9HT450B is proudly made in the USA and backed by QA1's lifetime guarantee to remain within 2% of its original free height and spring rate under normal operating conditions. The durable powder-coated finish is suitable for long-term use, while the carefully engineered design delivers a practical balance of strength, weight savings, and suspension performance. Verify spring rate, inner diameter, free length, and application requirements before installation.
