Description

Race-Proven Performance. Daily Driver Comfort.

Fox direct replacement shocks deliver race-winning performance in a simple direct replacement bolt on shock. Each application has been rigorously tested by Fox's engineers to maximize suspension travel and performance on and off the road. Direct replacement shocks are available in hundreds of applications from stock to lifted, as well as aftermarket kit replacements.

FOX's new Hydraulic Top Out (HTO) technology offers usable position-sensitive rebound damping control on and off the pavement. HTO reduces harsh top-outs and increases comfort by forcing shock oil through a secondary shim stack to slow down shock shaft speed; HTO is particularly beneficial after installing heavier, aggressive tires and applications lifted higher than OEM specification.
