5th Wheel King Pin Boxes

5th Wheel King Pin Boxes

Air pin boxes act as buffers, arresting the transfer of road impact between the tow vehicle and the coach to produce smooth towing performance. A vehicle and a trailer connected by a standard fifth wheel connection will tend to fight each other as you travel at highway speeds. Our new Flex Air Pin Box combines our time-tested Trailair air ride technology with our Rota-Flex pivoting head to significantly reduce fore to aft movement and vertical tug-of-war between a fifth-wheel RV and tow vehicle.
