This smooth body shock uses non-adjustable valving for a controlled upgrade over the factory rear unit, with a collapsed length of 11.625in and an extended length of 17.75in. 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.
