Flex Air® Pin Box

The Flex Air Pin Box combines our time-tested Trailair® air ride technology with our Rota-Flex® pivoting head to create an unparalleled ride, eliminating chucking and the vertical tug-of-war between the fifth-wheel and tow vehicle.

Upgrade to the Comfort of Air

Trailair® was first to the market with air ride for fifth-wheel RVs and still leads the way with innovative fifth-wheel pin box technology. Our new Flex Air Pin Box combines our time-tested Trailair air ride technology with our Rota-Flex® pivoting head to provide an unparalleled ride, eliminating chucking and the vertical tug-of-war between the fifth-wheel and tow vehicle.

How it Works

  • Our integrated air bag acts as a buffer between the tow vehicle and coach to absorb road shock and vibrations that can damage an RV.
  • As the air bag absorbs road shock and vibration, the oil shock absorber handles rebound action, dampening kickback and controlling chucking.
  • The heavy-duty pivoting head in its lower jaw controls the vertical tug-of-war between the tow vehicle and RV.
  • The durable rubberized compound provides an additional buffer to help protect the RV from jarring motion.
