Hey Christopher, thanks for reaching out. I can certainly point you in the right direction. The best way to determine what bearings you need for your 5th wheel is with the casting number on the hub. Brake drums have a casting number right on the front so you can remove one wheel and you should be able to easily see it. It is typically a 4 digit series of numbers like 8-219 or something.
So for example, if your casting number is 8-219, the bearing kit # BK3-200 is what you would need.
Let me know that casting number and I can make absolutely sure you get the right thing.
