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.
