Fox Shocks Performance Series 2.0 IFP (MPN: 985-24-259)

Advanced shock technology for enhanced ride quality and handling.

The Fox Shocks Performance Series 2.0 IFP is engineered to elevate the performance of trucks and SUVs through advanced shock technology. Featuring a hydraulic and nitrogen gas charged design, this shock absorber ensures a smooth on-road experience while maintaining predictable handling in off-road conditions. The aluminum body is precision crafted from 6061-T6 material, providing excellent cooling capacity and resistance to rust over time.

This shock utilizes an Internal Floating Piston (IFP) mono-tube design that effectively separates the shock oil from the nitrogen gas chamber, minimizing oil aeration and maximizing performance. The race-developed high flow damping piston, combined with application-specific valving, delivers a consistent ride quality that can withstand challenging terrains. The redundant sealing pack system enhances durability, ensuring long-lasting performance under various conditions.

With a clear-anodized finish, the shock not only performs well but also maintains its appearance over time. The 5/8 inch hard chrome plated heat-treated alloy steel shaft contributes to the overall strength and reliability of the shock. Designed for vehicle-specific applications, the Performance Series 2.0 IFP is a single unit that does not include additional hardware or dust shields, making it a straightforward choice for enhancing your vehicle's suspension system.
