Part Number: 985-24-189

Summary: The FOX Performance Series 2.0 IFP smooth body shocks utilize the latest in Internal Floating Piston (IFP) technology to transform the handling of your GMC Sierra 3500HD. This monotube design is engineered to provide a comfortable on-road ride while maintaining predictable off-road control in challenging conditions. By separating the shock oil from the high-pressure nitrogen-charged gas chamber, these shocks deliver consistent performance and eliminate oil aeration for drivers seeking an upgrade over factory equipment.

Features

• Internal Floating Piston (IFP): Monotube reservoir design provides separation between shock oil and the high-pressure nitrogen chamber to ensure maximum performance from the precision valving.
• Aluminum Body: 2.0” Impact extruded and CNC machined 6061-T6 clear anodized aluminum provides increased cooling capacity to ensure rust resistance over time.
• High-Flow Piston: Race-developed piston design provides application-specific valving to ensure a predictable ride quality tailored to the vehicle.
• Hard Chrome Plated Shaft: 5/8 inches heat-treated alloy steel provides a durable surface to ensure long-term seal integrity.
• Advanced Suspension Fluid: JM92 oil provides consistent damping properties across variable temperatures to ensure performance stability.

Technical Specifications

Fitment

• 2011-2019 GMC Sierra 3500HD
• Note: Fits both 2WD and 4WD models.

What’s Included

• Includes 4 Shocks (2 Front Shocks and 2 Rear Shocks)
• Quiet nitrile rubber bushings

Why Choose This Product?

• Engineering Advantage: The Internal Floating Piston (IFP) monotube architecture prevents the mixing of gas and oil, a common failure point in standard shocks that leads to performance fade.
• Performance Benefit: Drivers experience improved heat management and more responsive damping, resulting in a more controlled feel on both paved roads and rough terrain.

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 more consistent performance from the factory-tuned valving.

Are these shocks resistant to corrosion?
Yes, the shock bodies are constructed from impact-extruded 6061-T6 clear anodized aluminum, which naturally resists rust and improves cooling capacity.

What lift height are these shocks compatible with?
These shocks are designed for GMC Sierra 3500HD models with 0 to 3.5 inches of lift.
