Fox Racing Shocks Performance Series IFP HTO Shock

The Fox Racing Shocks Performance Series IFP HTO Shock is a bolt-on smooth body shock absorber (also called a coil-over or shock, depending on the application). It is built to improve damping control and ride comfort on the street and off-road. It combines an internal floating piston design with Hydraulic Top Out technology. Fox tunes it for each specific application.

Key Features:

• Impact-extruded 6061-T6 aluminum body: The body is built for strength and efficient heat dissipation.
• Type II clear-anodized plating: This finish resists corrosion.
• Internal Floating Piston (IFP): The piston separates the shock oil from the high-pressure nitrogen charge. This helps limit oil aeration and optimizes damping.
• Hydraulic Top Out (HTO): This adds position-sensitive rebound damping. It sends oil through a secondary shim stack to slow the shaft near full extension, which reduces harsh top-outs.
• Hard chrome shaft: The shaft is built for durability and smooth operation.
• High-flow, velocity-sensitive damping: This helps keep the ride controlled across a range of terrain.
• Application-specific valving: The tune is matched to the intended use.
• Serviceable design: The shock is rebuildable and re-tunable for long-term ownership.

HTO is especially helpful on lifted vehicles or those running heavier, more aggressive tires. The Performance Series gives you a dependable upgrade from the standard shock. It comes from Fox, a brand known for suspension technology developed in racing and off-road use.
