The most comfortable towing experience.
The Flex Air(R) Pin Box combines Lippert's time-tested Trailair(R) Air Rideâ„¢ technology with its Rota-Flex(R) 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(R) 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.
