Fox 2.5 Performance Series HTO Coil-Over 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.
