Part Number: 985-24-269

Summary: The FOX Performance Series 2.0 IFP (Internal Floating Piston) smooth body shocks are engineered to transform the performance of your GMC Sierra 1500. These shocks utilize a mono-tube design to separate shock oil from the high-pressure nitrogen chamber, ensuring consistent damping in various conditions. Built with a precision metal impact aluminum body, they provide increased cooling capacity and rust resistance for both on-road comfort and predictable off-road handling.

Features

• Internal Floating Piston (IFP): 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 a durable, rust-resistant finish.
• Performance Valving: Application-specific valving and high-flow damping pistons provide a 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 robust surface to ensure long-term seal integrity and durability.

Why Choose This Product?

• Engineering Advantage: The Internal Floating Piston (IFP) technology prevents the mixing of oil and gas, maintaining damping consistency that standard twin-tube shocks cannot match.
• Performance Benefit: Drivers experience a significant improvement in ride predictability and heat management, resulting in a more controlled feel during both daily driving and off-road use.

Frequently Asked Questions

What is the benefit of the IFP design?
The Internal Floating Piston (IFP) separates the oil from the nitrogen gas, which eliminates oil aeration and allows the factory-tuned valving to perform at its peak without fading.

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

Will these fit the AT4X model?
No, according to the fitment notes provided, these shocks specifically exclude the AT4X model.
