5th Airborne is the latest product innovation from FABEX, manufacturer of pin boxes... Your fifth-wheel takes a lot of abuse from turbulence caused by potholes, section  dividers, bridge decks and heavily worn interstate highways. The 5th Airborne premium fifth-wheel air-ride coupler acts as a buffer between the tow vehicle and the trailer, minimizing the challenges in the road. This significantly reduces the negative impact of vertical shock and longitudinal chucking. The 5th Airborne does more than improve your ride; it protects your investments by relieving stress on your coach’s frame, cabinets, mechanicals, and support mechanisms. Reduced vibration also saves your contents. Furniture, appliances, TVs, computers, dishes, glassware and other fragile items stay in their places. Drivers and passengers also benefit from reduced fatigue and the improved safety provided by the 5th Airborne’s smooth ride.

The 5th Airborne premium fifth-wheel air-ride coupler was engineered and developed by long-time veterans of the towing industry. They put the product through grueling tests to measure its performance against the top two competing premium couplers on the market. The 5th Airborne coupler, with its innovative forward pivot design, out- performed both leading competitors. Test measurements were recorded in both the vertical (air-ride softening) direction and the longitudinal (anti-chucking) direction. The documented results proved that the 5th Airborne performed significantly better in both orientations.

The streamlined, high-tech design of 5th Airborne adds a touch of class to the otherwise mechanical-looking hitch. 5thAirborne is engineered with a 21,000-lb. rating. 5th Airborne is designed to allow tuning of the air-spring, a feature that permits adjustment to optimize the performance of each rig combination. The air-spring is enclosed within the coupler, providing protection from UV exposure and road hazards.
