Fox Racing Shocks Performance Series Smooth Body IFP HTO Shock Absorber

Fox Racing Shocks Performance Series Smooth Body IFP HTO shock absorbers are bolt-on replacement shocks. They improve ride quality, damping control and stability on and off the pavement. Each shock combines an Internal Floating Piston (IFP) design with Hydraulic Top Out (HTO) technology. This gives you more controlled rebound and a more comfortable ride on trucks and SUVs, whether lifted or not.

Key Features:

• Hydraulic Top Out (HTO) technology: position-sensitive rebound damping slows the shaft near full extension. This reduces harsh top-outs and helps keep the vehicle composed.
• Internal Floating Piston (IFP): separates the shock oil from the high-pressure nitrogen charge. This helps dissipate heat and keeps damping consistent.
• Smooth, corrosion-resistant body: the aluminum body has Type II clear-anodized plating that resists rust and corrosion over time.
• High-flow, velocity-sensitive damping: adds control over rough roads and trails without giving up everyday comfort.
• Hard chrome shaft: built for durability and smooth operation.
• Vehicle-specific valving: tuned for each application to improve on- and off-road performance.
• Bolt-on installation: works as a direct replacement for the factory shock.

The Performance Series draws on Fox's off-road racing experience. It suits drivers who run larger, heavier tires or lifted suspensions, and drivers who want better ride control than stock shocks give. Choose the matching option for your application from the variants listed.
