Inspired by it's off-road racing predecessors, the new Factory Series bump stop combines race proven technology with new, cutting-edge features to provide increased damping performance and bottom out control in the last few inches of suspension travel. The threaded body allows you to adjust the mounting height to fine-tune when the bump stop engages during up travel, preventing harsh bottom outs. An Internal Floating Piston (IFP) in the shaft separates the oil and nitrogen to prevent cavitation and bucking while the negative coil spring softens initial impacts and harsh top outs. The integrated FOX AIR VALVE (FAV) is located at the bottom of the shaft for easy access and is protected by the replaceable strike pad. Factory Series bump stops allow you to use every inch of suspension travel without harsh bottoming.
Bob Fox, founder of Fox Racing Shox, had a dream in 1957. That was to create a better shock absorber for dirtbike racing. From that dream Bob Fox built and grew Fox Racing Shox. Now Fox Racing Shox creates the type of performance shock absorbers that lead the Fox team to victory in the 2015 UTV World Championships and lead to the FOX Athletes dominating in the 2016 Mint 400. Fox has over four decades of experience manufacturing shocks that are meant to win in a variety of motorsports. Fox engineers take what they learn from dirtbike, mountain biking and drag racing and apply that technical knowledge to the development of off-road shocks. So Fox innovation and product support is top of the line. Shop Fox Racing Shox Now
