    The QA1 Stocker Star Series front shock brings stock mount aluminum performance to classic Ford and Mercury models including the Mustang, Fairlane, Falcon, Torino, Comet, Cougar and Cyclone. This smooth body shock uses single adjustable valving for a controlled upgrade over the factory front unit, with a collapsed length of 9.25in and an extended length of 14.125in. Each shock is machined from lightweight billet aluminum, is 100 percent dyno tested and serialized, and stays serviceable and rebuildable through QA1 or a QA1 authorized service center. It is a bolt-in fit that works with the factory suspension, needs no cutting or welding, is made in the USA, and carries a limited lifetime warranty.
