Description
Fox Performance Series 2.0 IFP Rear Shock 1999-2019 GM (3.5″–6.5″ Lift)
Upgrade your suspension with the Fox Performance Series 2.0 IFP Smooth Body Shock, engineered with the latest in shock technology to transform the performance of your truck or SUV. Utilizing race-proven damping control, these shocks deliver a comfortable on-road ride while maintaining predictable handling in even the toughest off-road conditions.
The Performance Series 2.0 IFP shock is built around a precision aluminum smooth body, which increases cooling capacity and will not rust over time. Inside, Fox’s race-proven performance valving works in conjunction with a high-flow damping piston to deliver a predictable and controlled ride across a wide range of conditions. The monotube Internal Floating Piston (IFP) design separates shock oil from the high-pressure nitrogen gas chamber, eliminating oil aeration and ensuring consistent damping performance. This advanced design allows the shock to maintain maximum efficiency, even under demanding use. Combined with application-specific tuning, these shocks provide a balanced ride quality that handles rough terrain with confidence while still maintaining comfort for daily driving.
Key Features
- Monotube IFP (Internal Floating Piston) design for consistent damping
- Precision metal impact aluminum body for increased cooling and corrosion resistance
- Race-proven high-flow damping piston with application-specific valving
- Nitrogen-charged design to reduce shock fade and improve performance
- Direct bolt-on replacement for factory shocks
- Designed for reliable performance on and off the road
