QA1 Pro Coil High Travel Coil-Over Spring - 4.125" ID - 11.000" Length - 250 lb/in Spring Rate - Silver Powder Coat P0100011 900 rpm down to 10Available 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.
