Description

The Ultra-Fab Trailair Air-Ride King Pin Box (Part Number 35-946203) is a fifth-wheel trailer hitch pin box designed to provide a smoother, more stabilized towing experience. It features an air-ride coupler with a king pin and has a gross vehicle weight capacity of 21,000 pounds. The unique scissor action and integrated air bag absorb road impact and dissipate forces between the tow vehicle and the coach, reducing bumps, chucks, and jars. This improves the overall ride for the truck and its occupants, as well as protecting the fifth-wheel trailer and its contents. The pin box is finished in black and has a 2-row bolt pattern with 7-7/8 inch horizontal and 2 inch vertical mounting bolt spacing. It comes with a limited 1-year warranty.
