Comparing Pin Box On Trailer To Trailair Flex Air 5th Wheel Pin Box
Question:
I want to compare the size of the Flex Air to my current TrailAir pin box. I have searched the web, but have not found a spec drawing that shows all of the pertinent dimensions. Can you provide a URL for this?

I do not have a drawing of the Trailair Flex Air 5th Wheel Pin Box, part # LC328492 showing dimensions but I can help you with the dimensions.
The pin box you came from would have the same dimensions as a Lippert 1621 pin box. The distance from the rear mounting holes to the center of the king pin should be 25-5/8 inches. That would also be the distance for a replacement pin box like part # LC328492.
I have attached a helpful article that has a chart with the dimensions you are looking for. If you find you have a different measurement than what is listed on the chart let me know what you measure and I will try to help you out further.
