Internal IFP mono-tube reservoir design Upgrade the on-road comfort and off-road control of your 2017-2021 Ford F-250 or F-350 Super Duty 4WD to FOX Performance Series 2.0 IFP (internal floating piston) rear shocks. The mono-tube design's internal reservoir 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.
FOX and BDS joined forces to custom valve each application to work perfectly with each BDS Suspension system. Based on FOX race products but re-designed to turn your BDS-equipped truck into an off-road machine providing a predictable ride - capable of handling the roughest conditions with fade-free performance.
