Advanced shock technology for enhanced ride quality and handling.
The Fox Shocks Performance Series 2.0 IFP is engineered to elevate the performance of trucks and SUVs through advanced shock technology. Featuring a hydraulic and nitrogen gas charged design, this shock absorber utilizes a mono-tube construction with an Internal Floating Piston (IFP) that effectively separates the shock oil from the gas chamber, preventing oil aeration and ensuring consistent performance. The race-developed high flow damping piston, combined with application-specific valving, delivers predictable ride quality even in challenging conditions.
Constructed from a 2.0 inch impact extruded and CNC machined 6061-T6 aluminum body, the shock is designed to resist rust and provide durability over time. The clear-anodized finish enhances its longevity while the black-anodized components add to its robust design. The 5/8 inch hard chrome plated heat-treated alloy steel shaft and a redundant sealing pack system ensure reliability and performance under various conditions.
This shock absorber is designed for vehicle-specific applications and features non-adjustable valving, making it a straightforward solution for those seeking improved handling and comfort. The use of JM92 advanced suspension fluid allows for optimal performance across a range of temperatures, while the quiet nitrile rubber bushings facilitate increased suspension articulation. The Performance Series 2.0 IFP shock is a single unit that does not include dust shields or hardware, making it a focused choice for serious off-road enthusiasts.
