High Travel Powder coated Coil Springs are proudly made in the USA and are available in 7", 9", 10", 12" and 14" lengths with a powder coated, chrome appearing finish. These 2-1/2" I.D. high travel springs are manufactured from specially designed high-tensile, chrome silicon alloy spring wire, which allows them to have fewer coils and a smaller wire diameter. As a result, these springs 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. In addition, this high-grade material, along with careful heat-treating and post-processing, allows for greatly improved fatigue life, and the coil design allows the springs to be compressed to coil-bind without affecting spring rate or free height. These new high travel springs are ground at both ends for straight, consistent and accurate operations. In addition, all springs are lifetime guaranteed to remain within 2% of the original free height and rate under normal operating conditions. Thank you for choosing POWER PRO!
