Construction & Design:

The FOX Performance Series Rear Shock features a precision-engineered aluminum body that excels in heat dissipation, critical for maintaining consistent damping during demanding driving conditions. The smooth seamless alloy body is CNC machined and anodized for durability and corrosion resistance, ensuring the shock withstands the rigors of off-road use and exposure to the elements.

At the heart of the shock is the race-developed main piston paired with a true Internal Floating Piston (IFP) that effectively separates oil from high-pressure nitrogen gas. This design minimizes cavitation and shock fade, delivering reliable and repeatable performance. The inclusion of Teflon-lined, heat-treated spherical bearings further enhances durability and smooth operation throughout the suspension’s travel.
