FLEX AIR PIN BOXES
Controls Chucking, Dampens Road Shock and Rebound


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.


  • Air bag absorbs road shock and vibration, the oil shock absorber handles rebound action dampening kickback and controlling chucking

  • The integrated air bag acts as a buffer between the tow vehicle and coach to absorb road shock and vibrations

  • The heavy-duty pivoting head in its lower jaw controls the fore to aft movement known as chucking




    • AIR RIDE PIN BOXES
    Dampens Road Shock and Kickback


    The Air Ride Pin Box acts as a buffer between the tow vehicle and RV, arresting the impact of road shock and stabilizing the towing performance. How? Simple — the unique scissor action allows the air bag to absorb road shock and vibration while the gas shock handles the rebound or bounce effect, giving RVers a better, smoother ride.


  • Gas shock and air bag combination absorbs road shock and controls fore-to-aft coach movement, otherwise known as chucking

  • Protects from damage caused by road shock and vibrations, potentially saving owners from costly repairs

  • Dramatically improves ride and limits driver fatigue

  • Replaces popular LCI pin boxes; 16K (1621), 18K (1621), 21K long jaw (1621), 21K (1716), 18K (0719) and 21К (1116)
