Summary: The FOX Performance Series 2.0 IFP smooth body shocks utilize advanced monotube technology to transform the handling of your Ford Super Duty. By employing an Internal Floating Piston (IFP), these shocks provide a comfortable on-road ride while maintaining predictable off-road control in challenging conditions. The impact-extruded aluminum body ensures increased cooling capacity and long-term durability for trucks equipped with a 4-5 inch front lift.

Features

• Internal Floating Piston (IFP): The mono-tube design separates shock oil from the high-pressure, nitrogen-charged gas chamber to provide maximum performance by eliminating oil aeration.
• Aluminum Body: The 2.0-inch impact extruded and CNC machined 6061-T6 clear anodized aluminum one-piece body provides increased cooling capacity to ensure the shock resists rust over time.
• High-Flow Piston: A race-developed high-flow piston design provides application-specific valving to ensure a predictable ride quality capable of handling rough road conditions.
• Hard Chrome Shaft: A 5/8 inches hard chrome plated heat-treated alloy steel shaft provides increased strength to ensure long-term seal integrity.
• Redundant Sealing Pack: A specialized system featuring a main seal, wiper seal, and scraper seal provides superior protection to ensure internal components remain free of debris.

Frequently Asked Questions

What is the benefit of the IFP design?
The Internal Floating Piston (IFP) separates the shock oil from the high-pressure nitrogen gas, which eliminates oil aeration and allows the valving to perform consistently without fade.

Will these shocks rust over time?
No, the shocks feature a 6061-T6 clear anodized aluminum one-piece body that is specifically designed to resist rust and improve cooling.

Are these shocks compatible with a lifted truck?
Yes, these shocks are specifically valved and sized for 2017-2025 Ford F-250/350 4WD Super Duty models with a 4-5 inch front lift.
