Construction & Design
The FOX Performance Series 2.0 IFP shock features a lightweight impact-extruded 6061-T6 aluminum body that dissipates heat significantly faster than traditional steel shocks while resisting corrosion. Inside, the Internal Floating Piston separates the shock oil from the high-pressure nitrogen gas chamber to eliminate aeration and maintain consistent damping performance. Combined with FOX's race-developed high-flow piston and application-specific valving, the result is outstanding ride quality and long-term durability.
