Front Pro Coil double adjustable stock mount shock kit. Compressed length of 10.13" and extended length of 14". Includes 10" spring with rating of 550 and has a tapered flat end. These QA1 GM Pro Coil Systems are a great option for anyone looking for fully adjustable ride height and valving control. Choose a spring rate and adjustability that fits your driving style, adjust the valving to match and you are on your way. These shocks also utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely tune the weight balance for superior handling.
