Is Lippert 1621 Pin Box Different Height from Rota Flex that Fits 1621
Updated 08/18/2022 | Published 08/17/2022 >
Question:
Hi there I have a standard Lippert 1621 fifth wheel pin box. I was looking at the rotoflex pin box that is a replacement for the standard one. Question is what is the height difference between the two. It definitely looks like a different height. I need to know so I know if there is enough adjustment in height of my hitch to make it work

We've spoken with Trailair in the past about this exact question and the Rota-Flex part # LC328330 is going to sit right at 1 inch lower than the 1621 pin box you have currently.
