Part Number: 985-24-189

Summary: The FOX Performance Series 2.0 IFP smooth body shocks are engineered to transform the performance of your Chevy Silverado 3500HD. By utilizing an Internal Floating Piston (IFP), these shocks provide consistent damping by separating shock oil from the high-pressure nitrogen gas chamber. This design ensures rapid response and improved heat management compared to traditional twin-tube shocks, delivering predictable handling in both on-road and tough off-road conditions.

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” Impact extruded and CNC machined 6061-T6 clear anodized aluminum provides increased cooling capacity to ensure the shock resists rust over time.
• High-Flow Piston: Race-developed high-flow piston design provides application-specific valving to ensure a predictable ride quality capable of handling rough road conditions.
• Redundant Sealing Pack: Main seal, wiper seal, and scraper seal system provides a durable barrier to ensure long-term performance and protection against the elements.
