Product details

The Fox 987-24-021 2.5 Performance Series IFP HTO Shock Absorber is a bolt-on upgrade designed to enhance both on and off-road performance in your Ford F250/F350 Super Duty. These FOX Shocks feature position-sensitive technology, vehicle-specific valving, and larger pistons. The 2.5-inch shock body utilizes a type II anodized aluminum body that efficiently dissipates heat and prevents corrosion. An internal floating piston (IFP) is used to separate the shock oil from the high-pressure nitrogen, optimizing damping. As a result, the IFP helps eliminate oil aeration, allowing maximum performance from the factory-tuned precision valving.

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.
