Featuring Hydraulic Top Out (HTO) technology and an internal floating piston (IFP) to separate the shock oil from the high-pressure nitrogen, optimizing damping. These FOX shocks deliver consistent fade-resistant performance, reduce harsh top-outs, and increase comfort by forcing shock oil through a secondary shim stack to slow down shock shaft speed.
