# Fox 14+ Ram 2500 / 13+ Ram 3500 2-3in Lift Front 2.5 Perf. Series IFP HTO Shock

FOX 2.5 Performance Series HTO shock is a bolt-on shock loaded with position-sensitive technology vehicle-specific valving and larger pistons to improve on and off-road performance. A type II anodized aluminum body efficiently dissipates heat and prevents corrosion. The 2.5-inch shock body features an internal floating piston (IFP) to separate the shock oil from the high-pressure nitrogen optimizing damping. 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. Bolt-on 2.5 Performance Series HTO shocks to increase damping capacity and ride in comfort with position-sensitive rebound control.
