Helpful Expert Reply:

We have Trailair Flex Air fifth wheel pin box replacements for Lippert 1621 and Lippert 0719 pin boxes.

You will need to know what model pin box you have on your trailer to find the correct replacement. You can typically find that information on a sticker or a tag on the side of the pin box. If not and if it is the original pin box you can contact the dealership and give them the VIN and they should be able to tell you what pin box number was installed on your trailer.

If you find you have a Lippert 1621 pin box the replacement pin box you need is part # LC328492. If your pin box is a Lippert 0719, then the replacement pin box that will work for you is part # LC328484.
