FOX 2.5 Factory Series 12-Inch Air Shock, 1-5/8-Inch Shaft, Normal Valving, 40/80 - Black

FOX devotes countless hours of research and development to design race-winning suspension that withstands incredible punishment and provides consistent performance you can rely on. Regardless of whether you are flying high over the desert or struggling to stick to a rock face on an off-camber climb, our shocks will give you the damping performance, suspension control and proper spring rate to get the job done. Rebuildable and serviceable. Custom valving options available. In 1974, Bob Fox invented the first FOX Airshox for professional motocross racing. Air shock design allows for infinite adjustability of spring rate simply by varying nitrogen pressure. Incredibly strong hollow chromoly shafts also deliver reduced weight, making them ideal for competition rock crawlers.
