QA1 High Travel Coil-Over Spring - Coil-Over - 2.500" ID - 12" Length - 80 lb/in Spring Rate - Silver Powder Coat 1425011 We designed our Pro PistonAvailable 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.

As a result, these springs are lighter and have increased travel due to the larger distance between the coils.
