The most comfortable towing experience. The Flex Air® Pin Box combines Lippert's time-tested Trailair® Air Ride™ technology with its Rota-Flex® pivoting head to significantly reduce fore-to-aft movement and vertical tug-of-war between a fifth-wheel RV and tow vehicle, providing the user a more comfortable ride. The Flex Air® Pin Box utilizes an air bag to absorb road shock and vibrations, a rubberized compound to soften jarring motion, and an oil shock absorber to handle rebound action, dampen kickback and control chucking.
Note: Only compatible with Rhino™ Box pin box designs
