The QA1 QAP10HT375 high travel coil spring is engineered for suspension applications that require reduced weight, increased travel, and consistent performance. This spring features a 375 lb/in rate, a 2-1/2-inch inside diameter, and a 10-inch free length, making it a dependable choice for performance suspension builds. Its silver powder-coated finish provides durable protection while giving the spring a clean, professional appearance.
Manufactured in the USA from high-tensile chrome silicon alloy spring wire, the QA1 QAP10HT375 uses a lightweight coil design with fewer coils and a smaller wire diameter. This construction helps reduce unsprung weight, allows the spring to react faster, and provides increased travel between coils. The spring can compress to coil bind without changing its rate or free height, supporting predictable suspension operation during demanding use. Careful heat treating, shot peening, and post-processing improve strength, consistency, and fatigue resistance.
Both ends are ground and squared to promote straight, accurate operation, while the free length and spring rate are clearly marked for convenient identification. QA1 high travel springs are designed and manufactured to deliver long-term performance, and each spring is backed by a lifetime guarantee to remain within 2% of its original free height and rate under normal operating conditions. The QA1 QAP10HT375 is an excellent option for drivers and builders seeking a durable, lightweight coil spring with dependable performance characteristics.
