2017-2023 Ford Super Duty F-250 / 350 4WD FOX 2.0 Performance Series Shocks Front Pair
The Performance Series 2.0 IFP smooth body shocks contain the latest in shock technology to transform the performance of your Truck or SUV. They use our race-proven damping control to provide a comfortable on-road ride and predictable off-road handling in even the most challenging conditions.
The precision metal impact aluminum body increases cooling capacity and will never rust. Inside you will find our race-proven performance valving technology. Our Internal Floating Piston (IFP) mono-tube design separates the shock oil from the high-pressure, nitrogen-charged gas chamber. The IFP eliminates oil aeration allowing maximum performance from the factory-tuned precision valving. The race-developed high flow damping piston matched with application specific valving provides the Performance Series 2.0 IFP shock a predictable ride quality capable of handling the roughest road conditions.
