Question:
I have the lippert 1621 pin box and using anderson ultimate hitch so I need a pin box with a ball socket instead of a pin? does anyone make these? or I need to change my pin box to 4inch longer or 4inch shorter from the pin center to the first row of bolts do you have anything like that? thanks

You won't be able to get a longer/shorter pin box to match your Lippert 1621 pin box like # # LC328330 . Additionally, when using the Andersen Ultimate Hitch # AM3200 you can use the adapter that comes included with the system to turn your 5th wheel pin box into a gooseneck receiver to work on the Ultimate. Basically, the Andersen Ultimate comes with everything you need to make it work with your 5th wheel king pin, so there won't be any need to replace your pin box or get an adapter.
