Fox Racing Shocks Performance Series IFP HTO Shock Absorber

The Fox Racing Shocks Performance Series IFP HTO Shock Absorber is a bolt-on suspension upgrade. It is built to improve both on-road and off-road performance. Each shock has application-specific valving and a larger piston than a typical factory unit. This gives better damping control and more damping capacity. It suits daily driving, towing, and trail use.

Key Features:

• Internal floating piston (IFP): Separates the shock oil from the high-pressure nitrogen charge. This reduces oil aeration and helps keep damping consistent.
• Hydraulic Top Out (HTO) technology: Adds position-sensitive rebound damping control. It forces oil through a secondary shim stack near full extension. This softens harsh top-outs and improves ride comfort.
• Impact-extruded 6061-T6 aluminum body: Light and strong. It dissipates heat efficiently.
• Type II clear-anodized plating: Helps resist corrosion.
• Hard chrome plated shaft: Built for durability and smooth operation.
• High-flow, velocity-sensitive damping: Controls the ride across a range of driving conditions.
• Application-specific tuning: Valving is matched to the vehicle and suspension setup.
• Fully rebuildable and re-tunable: Can be serviced and revalved over its life.

HTO is especially useful on vehicles with heavier, more aggressive tires or a suspension lifted above factory height. Fox Racing Shocks is a long-established name in performance suspension. The Performance Series gives you a durable, serviceable shock with Fox damping technology. Choose the variant that matches your application.
