Summary: The FOX Performance Series 2.0 Smooth Body IFP shocks are engineered to transform the handling and ride quality of your GMC Sierra. Utilizing an Internal Floating Piston (IFP) mono-tube design, these shocks separate the shock oil from the high-pressure nitrogen chamber to eliminate oil aeration. This configuration ensures consistent, fade-free damping performance and a predictable ride quality whether navigating city streets or tackling tough off-road conditions.

Features

• Internal Floating Piston (IFP): Mono-tube reservoir design provides separation between oil and nitrogen gas to ensure maximum performance from the precision valving.
• 6061-T6 Aluminum Body: 2.0-inch impact extruded and CNC machined one-piece body provides increased cooling capacity to ensure the shock resists rust over time.
• High-Flow Piston: Race-developed design provides application-specific valving to ensure a comfortable on-road ride and predictable off-road handling.
• Hard Chrome Plated Shaft: 5/8 inches heat-treated alloy steel construction provides a durable surface to ensure long-term seal integrity.
• Nitrile Rubber Bushings: Quiet redundant sealing pack system provides increased suspension articulation to ensure reduced noise and improved durability.
