Construction & Design

The FOX 2.5 Performance Series Rear Shock features a smooth body design crafted from high-strength materials to resist wear and corrosion. The internal floating piston separates the oil and nitrogen gas, preventing foaming and ensuring consistent damping performance even during extended use. The high-temperature oil formulation is engineered to maintain viscosity and shock responsiveness under demanding conditions, such as off-road driving or heavy towing.

FOX’s precision engineering and rigorous quality control guarantee that each shock absorber meets strict performance standards. The robust construction and advanced sealing systems protect internal components from dirt, dust, and moisture, extending the service life of the shock.
