How to Pick Out Replacement Pin Box for Trailer


I was told that I needed to replace the kingpin on my 24k trailair 5th wheel box and I was wondering what options I have for replacement parts. I was looking at your trailair rotaflex and was wondering if that would work.


Expert Reply:

If you have to replace your pin box now would be a great time to go with a cushioned one. The Rotaflex like the part # LC328330 would be a great option as long as you have a Lippert 1621 or 1621HD pin box. This is a very common pin box so there is a great chance this is what you would need.

You will need to verify your pin box brand and model number before you order though to make sure this would fit. There should be a plate or sticker near the pin box with this info listed.

If you have a different one then you will need to check out the link I attached that all of the pin boxes we offer. You will need to select the one you have from the filters.
