Hello Heath. I do appreciate you reaching out, but I am sorry to say we do not offer a gooseneck coupler inner tube with a 3-3/4" OD. Everything we have is a standard 4" tube.
Do you know the brand of your gooseneck coupler? At this point the next step would be to look at replacing the entire gooseneck coupler with a new one such as the following:
- etrailer Gooseneck Coupler w/ Load Bearing Pin - 8" Adjustment - 2-5/16" Ball - 25K # e66MV
