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.
