Expert Reply:
I am not aware of a BT10 wheel hub. If it is reference to a spindle we have a BT8 or BTR spindle size. The BT8 has a 1" diameter for the bearings while the BTR is a 1-1/16" diameter for the bearings. If you have something different please let me know what size bearings and grease seal you have so I can verify if we have anything for your application.
If you have the BT8 it will use one of the following 4 lug hubs.
Standard Hub # AKIHUB-440-2-G-1K
EZ Lube Hub # AKIHUB-440-2-G-EZ-1K
If you have the BTR it will use one of the following 4 lug hubs.
Standard Hub # AKIHUB-440-2-G-2K
EZ Lube Hub # AKIHUB-440-2-G-EZ-2K

Hey, did you get a chance to check which spindle size your boat trailer uses—BT8 or BTR? Once you know the bearing and seal sizes, it’ll be easier to confirm which 4-lug hub fits best. Let me know what you find so we can narrow it down.
