In order to replace your Trailair Pin Box Model 1116, I recommend the Trailair Air Ride 5th Wheel Pin Box Model 1116 part # LC155943. The Trailair Flex Air 5th Wheel Pin Box Model 1621 part # LC369535 will not work. The Trailair Air Ride 5th Wheel Pin Box is the same as the Trailair Flex Air 5th Wheel Pin Box save for the pivoting head but there is not a Trailair Flex Air 5th Wheel Pin Box offered for a Model 1116.

I have a turning point trailair LCI item number 698341 Serial number S001665543. I want to upgrade to an air bag pin box. Which one will work with bolt pattern.

@James Hey James, The Lippert Turning Point Pin Boxes are a unique bolt pattern that only matches up to the Lippert Turning points. I spoke to Lippert and there is not a replacement pin box that works with that unit due to its unique welding and bolt patter. There is 1 5th wheel to gooseneck adapter pin box available, but there is not a replacement air bag option out there.
