Part Number: 985-24-241

Summary: The FOX Performance Series 2.0 IFP smooth body shocks utilize advanced monotube technology to transform the handling of your Chevrolet Silverado. Featuring an Internal Floating Piston (IFP), these shocks isolate the high-pressure nitrogen gas from the shock oil to prevent aeration and ensure consistent damping. This design provides a comfortable on-road ride and predictable off-road handling even when navigating tough conditions with 1.5-3 inches of rear 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 from the factory-tuned precision valving to ensure oil aeration is eliminated.
• Aluminum Body: 2.0-inch impact extruded and CNC machined 6061-T6 clear anodized aluminum provides increased cooling capacity to ensure the one-piece body resists rust over time.
• High-Flow Piston: Race-developed piston design matched with application specific valving provides predictable ride quality to ensure the vehicle can handle the roughest road conditions.
• Hard Chrome Plated Shaft: 5/8-inch heat-treated alloy steel construction provides a durable surface to ensure long-term structural integrity.

Why Choose This Product?

• Engineering Advantage: The use of an Internal Floating Piston (IFP) within a clear-anodized aluminum body allows for superior heat dissipation and eliminates oil foaming, maintaining damping consistency that standard twin-tube shocks cannot match.
• Performance Benefit: Drivers experience a significant improvement in both street comfort and off-road predictability thanks to application-specific valving designed specifically for the Silverado heavy-duty platform.

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 prevents the oil from aerating (foaming) to ensure consistent damping performance.

Are these shocks resistant to rust?
Yes, the 6061-T6 aluminum body is clear-anodized and CNC machined to resist rust and corrosion over time.

Do these shocks work with a lifted truck?
These shocks are specifically configured for Chevrolet Silverado 2500/3500 models with 1.5 to 3 inches of rear lift.
