The QA1 QAP12HT550B high travel coil spring is designed for suspension applications that require reduced weight, increased travel, and responsive performance. It features a 550 lb/in spring rate, a 2-1/2-inch inside diameter, and a 12-inch free length, making it a dependable choice for performance-oriented automotive suspension setups. The durable black powder-coated finish provides added protection and a clean appearance.
Manufactured in the USA 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 increased spacing between coils allows greater suspension travel while reducing unsprung weight. Lower unsprung weight helps the suspension react faster, supporting improved handling, traction, and overall suspension response during demanding driving conditions.
The QA1 QAP12HT550B is built for durability and consistent performance under normal operating conditions. QA1 backs its springs with a lifetime guarantee to remain within 2 percent of the original free height and spring rate. This coil spring is an excellent option for automotive enthusiasts, racers, and builders seeking a lightweight, high-performance spring with reliable specifications and USA-made quality.
