Fox 2.0 Performance Series IFP Rear Shocks for 1999+ Ford F250/F350 Super Duty
The 2.0 Performance Series Shocks delivers race-dominating performance in a hassle free bolt-on package. Their heat-reducing design includes a metal-impacted aluminum shock body that dissipates heat faster than conventional steel. Inside the Internal Floating Piston (IFP) separates shock oil from a high-pressure nitrogen gas chamber that provides a predicable ride quality capable of handling the roughest road conditions. Combine these new technologies with a competitive price for a winning combination.
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 toughest 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 predicable ride quality capable of handling the roughest road conditions.
NOTE: Fitment is for F250 & F350 Pickups only, shocks may fit Cab and Chassis models and/or F450/F550 models; please call to confirm.
