Flex Air® Pin Box

The Flex Air® Pin Box unifies time-tested Trailair® Air Ride technology with the Rota-Flex® pivoting head to reduce chucking and vertical tug-of-war between a fifth-wheel RV and tow vehicle, providing a more comfortable ride. Flex Air utilizes an air bag and rubberized compound to absorb road shock and vibrations, an integrated oil shock absorber to dampen kickback, and a pivoting head to control chucking.

 
  • 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.
