Construction & Design

The Performance Series 2.0 IFP Rear Shock features a lightweight 6061-T6 aluminum monotube body that dissipates heat more efficiently than conventional steel shocks while resisting corrosion. FOX's Internal Floating Piston separates the shock oil from the high-pressure nitrogen chamber, preventing aeration and ensuring fade-free damping under demanding conditions. Combined with FOX's race-developed high-flow piston and vehicle-specific valving, the result is exceptional ride quality, durability, and control.

Whether you're towing heavy trailers, hauling equipment, or exploring rough backroads, the FOX Performance Series 2.0 IFP Rear Shock provides improved suspension control, reduced body movement, and greater confidence over uneven terrain. The monotube design maintains consistent damping during extended use, helping reduce shock fade while delivering a smoother, more controlled ride both on and off the pavement.
