Hello Floyd, thanks for reaching out. The Lippert part number 7362711 comes back as the 1621 pin box. So the Curt Flex Air 5th Wheel Pin Box # LC328492 you were looking at would be the correct replacement for this. It has an 18K capacity.

Let me know if there is anything else I can do to help.

Hey Floyd, did the Curt Flex Air 5th Wheel Pin Box work out as a replacement for your Lippert hitch? I'm asking because your experience could help others looking for a similar solution.

@JesseM I had to trim about one inch from the top of the new pin box to get the height that I wanted. I really like the ride that and the extra cushion from this new pin box.

@FloydM Gotcha. That is one way to do it. We typically don't recommend modifying a new product like that, but I will keep this in mind as a potential option for height adjustment. A lot of people come to us looking for ways to adjust the height beyond the adjustments on the pin box and/or 5th wheel hitch. Will keep this one in my back pocket lol. Anyway, thanks for sharing. Feel free to come find me anytime you need anything.
