Fox 1.5-3.5 inches 2.0 IFP Front Lift Shocks For 2011-2019 Chevy Silverado 2500HD 2WD/4WD

Part Number: 2×985-24-189

Summary: FOX Performance Series 2.0 IFP smooth body shocks utilize advanced monotube technology to transform the handling performance of your Chevy Silverado 2500HD. By utilizing an Internal Floating Piston (IFP), these shocks separate the shock oil from the high-pressure nitrogen chamber to eliminate oil aeration. This design ensures the application-specific valving provides a predictable ride quality and consistent damping in both on-road and tough off-road conditions.

Features

• Internal Floating Piston (IFP): Monotube reservoir design provides separation of oil and nitrogen to ensure maximum performance from the factory-tuned valving.
• Aluminum Body: 2.0” Impact extruded 6061-T6 clear anodized aluminum provides increased cooling capacity to ensure a rust-resistant, durable finish.
• High-Flow Piston: Race-developed piston design provides application-specific valving to ensure a predictable ride capable of handling rough road conditions.
• Hard Chrome Shaft: 5/8 inches heat-treated alloy steel construction provides a robust surface to ensure long-term durability and seal integrity.
• Redundant Sealing Pack: Main seal, wiper seal, and scraper seal system provides multiple layers of protection to ensure performance in variable environments.

Technical Specifications

Fitment

• 2011-2019 Chevy Silverado 2500HD (2WD/4WD)
• Note: Designed for front fitment on vehicles with 1.5-3.5 inches of lift.

What’s Included

• Includes 2 Shocks

Why Choose This Product?

• Engineering Advantage: The Internal Floating Piston (IFP) architecture prevents oil foaming by physically isolating the gas and oil, maintaining damping consistency that twin-tube shocks cannot match.
• Performance Benefit: Drivers experience improved cooling and faster suspension response times, leading to more controlled handling during repeated impacts.

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-charged gas chamber, which eliminates oil aeration and allows for consistent performance from the precision valving.

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

What lift height are these shocks compatible with?
These front shocks are specifically designed for 2011-2019 Chevy Silverado 2500HD models with 1.5 inches to 3.5 inches of lift.
