Summary: The FOX Performance Series 2.0 IFP smooth body shocks are engineered to transform the performance of your GMC Sierra 2500 or 3500. Utilizing an Internal Floating Piston (IFP) design, these shocks separate shock oil from the high-pressure nitrogen-charged gas chamber to eliminate oil aeration. This technology, combined with race-proven performance valving, provides a comfortable on-road ride and predictable off-road handling even in tough conditions.

Features

• Internal Floating Piston (IFP): Mono-tube design separates shock oil from the high-pressure nitrogen gas chamber to provide maximum performance from the factory-tuned precision valving by eliminating oil aeration.
• Aluminum Body: 2.0” Impact extruded and CNC machined 6061-T6 clear anodized aluminum construction provides increased cooling capacity to ensure the body resists rust over time.
• High-Flow Piston: Race-developed piston design provides application-specific valving to ensure a predictable ride quality capable of handling rough road conditions.
• Redundant Sealing Pack: Main seal, wiper seal, and scraper seal system provides a robust barrier to ensure long-term durability in harsh environments.

Frequently Asked Questions

What is the benefit of the IFP design?
The Internal Floating Piston (IFP) separates the shock oil from the nitrogen gas, which prevents oil aeration and allows the valving to function with maximum precision and consistency.

Are these shocks resistant to rust?
Yes, the 2.0 inches impact extruded body is made from 6061-T6 clear-anodized aluminum, which naturally resists rust and corrosion over time.

What lift height are these shocks compatible with?
These shocks are specifically designed for 2020-2023 GMC Sierra 2500/3500 models equipped with 1.5 inches to 3 inches of rear lift.
