Fox Performance Series 2.5 IFP HTO Shock, Rear (3.5-4in Lift)

FOX 2.5 Performance Series HTO 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 to increase damping capacity and ride in comfort with position-sensitive rebound control.

Features and Benefits
