Rear Heavy-Duty Shock Upgrade – KONI FSD for Ford F550 & F600 4WD (2017+)

Koni Frequency Selective Damping (FSD) shock absorbers provide superior handling characteristics without compromising ride comfort. The FSD is firm where you need it, such as through corners, but rides soft over expansion joints and rough roads. A special valve filters out annoying vibrations before they enter the vehicle, resulting in a smooth ride over a variety of road surfaces.


Applications:
  • Ford F550 & F600 4WD 2017+ (Will not fit 2wd or lifted models)
