Fox 13+ Ram 3500 0-3in Lift Rear 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.

Special Note for Dodge Ram (Classic/DT/DS)

Since Dodge/Ram manufacturered concurrent Ram 1500, 2500 & 3500 models on both new and old body designs, please ensure you select the parts to suit the correct submodel. The year alone may not always be a reliable way to verify your submodel in the case of some Rams, so we encourage you to double check if you have the Classic, or the new shape when making orders for parts that are not the identical between both styles.
