QA1 Pro Coil High Travel Coil-Over Spring - 3.500" ID 10.0" Length 550 lb/in Spring Rate - Single Pigtail 29000P 7L FRONT O2 SENSOR EXTENSIONAvailable 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.
