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.
Uncompromised performance through FOX’s patented internal bypass technology delivers the feel of near-endless suspension travel. Exclusive internal bypass technology allows oil to flow around the piston at some points of the stroke – while creating humongous pressure at other points – supporting the vehicle like no other product can.
Floating through terrain is accomplished with FOX’s ride zone – combining a race-developed shock piston, internal bypass and Dual Speed Compression adjustment – allowing fine tuning for weight, terrain and speed.
Dominate any terrain with the brute strength of 3- and 2.5-inch aluminum bodies, cactus cooler reservoirs and 7/8” shafts with redundant seals, all proven in the harshest of environments under the toughest of conditions.
