QA1 Pro Coil High Travel Coil-Over Spring Coil-Over 3.500" ID 10.0" Length - 500 lb/in Spring Rate Braided Nylon Hose Bearings and outer races areAvailable in 7", 9", 10", 12", 14" and 16" lengths, QA1 offers an assortment of high travel springs with a silver powder coated finish. 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. As a result, these springs are lighter and have increased travel due to the larger distance between the coils.
