Fits: OEM Part number: Fabex 663, M&M 663, Lippert 7019. Your fifth-wheel takes a lot of abuse from turbulence caused by potholes, section dividers, bridge decks and heavily worn interstate highways. The 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.
