Fox Performance 2.0 IFP Smooth Body 2.5-4 inches Rear Lift Shocks for 2019-2025 GMC Sierra 1500 Limited

Part Number: 985-24-269

Summary: The FOX Performance Series 2.0 IFP smooth body shocks are engineered to transform your vehicle’s performance using advanced Internal Floating Piston (IFP) technology. Designed for the GMC Sierra 1500 Limited, these shocks provide precise damping control to improve both on-road comfort and off-road handling. The monotube design focuses on eliminating oil aeration to ensure consistent performance even in challenging driving conditions.

Features

• Internal Floating Piston (IFP): The 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-inch impact extruded and CNC machined 6061-T6 clear anodized aluminum provides increased cooling capacity to ensure the shock resists rust over time.
• Performance Valving: Application-specific valving and a high-flow damping piston provide predictable ride quality to ensure the vehicle can handle rough road conditions.
• Hard Chrome Shaft: 5/8 inches heat-treated alloy steel construction provides a durable surface to ensure long-term seal integrity.

Frequently Asked Questions

Is this shock rebuildable?
The provided documentation does not state that this specific model is rebuildable.

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

Does this fit the AT4X models?
No, this product explicitly excludes AT4X models according to the fitment notes.
