Part Number: 2×985-24-189_n3

Summary: The FOX Performance Series 2.0 IFP smooth body shocks are engineered to transform the performance of your GMC Sierra 3500HD. By utilizing an Internal Floating Piston (IFP) mono-tube design, these shocks separate the shock oil from the high-pressure nitrogen-charged gas chamber. This configuration eliminates oil aeration, providing predictable off-road handling and a comfortable on-road ride even in the toughest conditions.

Features

• Internal Floating Piston (IFP): The mono-tube design separates shock oil from the high-pressure gas chamber to provide maximum performance from the factory-tuned valving to ensure predictable ride quality.
• Impact Extruded Aluminum Body: The 2.0” CNC machined 6061-T6 clear anodized aluminum one-piece body provides increased cooling capacity to ensure the shock resists rust and maintains performance over time.
• Redundant Sealing Pack: A specialized system including a main seal, wiper seal, and scraper seal provides a durable barrier against contaminants to ensure long-term seal integrity.
• High-Flow Piston: The race-developed high-flow piston design matched with application specific valving provides consistent damping to ensure the vehicle can handle the roughest road conditions.

Why Choose This Product?

• Engineering Advantage: The use of an Internal Floating Piston (IFP) prevents oil aeration by keeping the nitrogen charge and oil separate, maintaining damping consistency that twin-tube shocks cannot match.
• Performance Benefit: Drivers experience improved heat management and fade resistance due to the impact-extruded aluminum body, resulting in stable handling across variable temperatures.

Frequently Asked Questions

Will these shocks fit vehicles with magnetic suspension?
No, according to the fitment notes, these shocks do not fit models equipped with magnetic suspension.

What is the benefit of the Internal Floating Piston (IFP)?
The IFP mono-tube design separates the shock oil from the high-pressure nitrogen-charged gas chamber, which eliminates oil aeration and allows for maximum performance from the precision valving.

Are these shocks resistant to rust?
Yes, the shocks feature a 2.0” impact extruded and CNC machined 6061-T6 clear anodized aluminum body designed to resist rust over time.
