Upgrade to the comfort of air

The most comfortable towing experience The Flex Air Pin Box combines LCI'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.

Quick Facts

  • Oil Shock - As the air bag absorbs road shock and vibration, the oil shock absorber handles rebound action dampening kickback and controlling chucking.
  • Air Ride Technology - 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.
  • Rubberized Compound - The durable rubberized compound provides an additional buffer to help protect the fifth-wheel RV from jarring motion.
  • Pivoting Head - The heavy-duty pivoting head in its lower jaw controls the fore to aft movement known as chucking.
