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.
