Recommended 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter To Improve Ride  


Do you have an air ride pin box that works with gooseneck adapter Will it be better on interstate for chucking than roto flex


Expert Reply:

We do offer Air Ride Goose Box pin boxes that will work with a gooseneck hitch in your truck.

The included air bag and dual shocks help provide cushion and reduce road shock, while improving the overall ride.

If you have a Lippert 1621, 0719, or 1621HD, or Fabex PB-600 series pin box on your trailer you can use part # RP85FR with a 20,000-lb capacity.

If you have a Lippert 1716, 0115, or 1116 pin box then the Air Ride Pin Box you can use is part # RP94716-61301. This has a 16,000 capacity.

We also offer Rota-Flex pin boxes that may work for your trailer. These systems use a rubber compound built into the head instead of air bags or shocks like the Air Ride. The rubber absorbs road shock and reduces chucking.

For a Lippert 1621 or 1621HD replacement you can use part # LC328330 for the 18,000-lb capacity.

For a 19,000-lb capacity and to replace the Lippert 1116 pin box you can use part # LC176440. For a Lippert 1621 and a 21,000-lb capacity you can use part # LC328329.

For my money I recommend the Air Ride system. The air bag and shocks will cushion a bit more than a hard rubber compound on the head of the pin box.
