Fox Racing Shocks Performance Series Smooth Body IFP HTO Shock

The Fox Performance Series Smooth Body IFP HTO Shock is a bolt-on replacement and upgrade shock absorber for trucks and SUVs. It brings race-proven damping technology from Fox to everyday driving. It gives a comfortable on-road ride and predictable off-road handling, and each shock is tuned for its specific application.

Key Features:

• Internal Floating Piston (IFP): Separates the shock oil from the high-pressure nitrogen charge. This helps dissipate heat and keeps damping consistent.
• Hydraulic Top Out (HTO): Position-sensitive rebound damping slows the shaft near full extension. This reduces harsh top-outs. It helps most with larger, heavier tires and with suspensions raised above factory height.
• Smooth aluminum body: Impact-extruded aluminum with Type II clear-anodized plating. It sheds heat and resists corrosion.
• Velocity-sensitive damping: High-flow valving gives controlled response over a range of road and trail conditions.
• Hard chrome shaft: Built for durability and smooth operation.
• Application-specific tune: Valving is matched to the intended vehicle and setup.
• Serviceable design: Fully rebuildable and re-tunable.

Fox Performance Series shocks are a bolt-on way to improve ride quality, control and damping capacity. They suit daily drivers, work trucks and off-road builds.
