QA1 offers an assortment of high travel springs available in 7" 9" 10" 12" 14" and 16" lengths with a silver powder coated finish. These springs are lighter and have increased travel due to the larger distance between the coils. Made in the USA these 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. These lighter springs optimize performance by reducing unsprung weight and reacting faster. This high-grade material along with careful heat-treating and post-processing gives the spring a much longer 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 silver powder coated and ground at both ends for straight consistent and accurate operations. In addition all QA1 springs are lifetime guaranteed to remain within 2% of the original free height and rate under normal operating conditions.
