Fox 2.0 Performance Series IFP Smooth Body Rear Shocks for use with the RockJock® Jeep JK suspension systems contain the latest in shock technology to transform the performance of your JK. They use Fox’s race-proven damping control to provide a comfortable on-road ride and predictable off-road handling in even the toughest conditions.
The precision metal impact aluminum body increases cooling capacity and will never rust. Inside you will find Fox’s race-proven performance valving technology. An 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 2.0 Performance Series IFP shock a predicable ride quality capable of handling the roughest road conditions.
