This Air Foil / Wing will bolt directly to any RBO roof without drilling or modifying. The shape of the airfoil helps to direct air over the cab and force it down into the bed. This flow of air helps to keep the rear window cleaner and also helps to keep dust out of the bed. Our testing also shows that the RBO Air Foil helps to reduce dust inside of the cab at certain speeds. Not only does the RBO Air Foil Improve Air Flow, it's sure to enhance the looks of any Side By Side out there. T
