Summary: The FOX Performance Series 2.0 IFP smooth body shocks are engineered to transform the performance of your GMC Sierra 2500/3500. Utilizing an Internal Floating Piston (IFP) mono-tube design, these shocks provide a comfortable on-road ride and predictable off-road handling even in tough conditions. The impact-extruded aluminum body increases cooling capacity and ensures long-term durability against rust, making this a comprehensive solution for leveled or slightly lifted heavy-duty trucks.

Features

• Internal Floating Piston (IFP): Mono-tube design separates shock oil from the high-pressure, nitrogen-charged gas chamber to provide maximum performance by eliminating oil aeration.
• Aluminum Body: 2.0” Impact extruded and CNC machined 6061-T6 clear anodized aluminum provides increased cooling capacity to ensure rust-resistant durability.
• High-Flow Piston: Race-developed piston design provides application-specific valving to ensure a predictable ride quality across various road conditions.
• Redundant Sealing: Multi-part pack system including main seal, wiper seal, and scraper seal provides protection against contaminants to ensure long-term seal integrity.

Frequently Asked Questions

What does the IFP design do?
The Internal Floating Piston (IFP) separates the shock oil from the nitrogen-charged gas chamber, which eliminates oil aeration and allows the precision valving to perform without fading.

Are these shocks resistant to rust?
Yes, the 2.0 inches bodies are constructed from impact-extruded 6061-T6 clear anodized aluminum, which resists rust over time.

Are there any specific requirements for installation?
The front shocks in this set require the use of an aftermarket Upper Control Arm for proper fitment and operation.
