Expert Reply:

The closest Bearing Buddy we offer to the 2-inches you said you measured on your hub is part # BB2047.

These protectors are designed for 2.047 inch inside hub diameters. There are two Bearing Buddy Protectors in the package.

The best way to make sure you would choose the Bearing Buddy that will work with your hubs is to use a digital caliper like part # PTW80157. If you find that you get a different measurement of your hub let me know and I will make a recommendation that will work for you.

I have attached a link to our product page for the Bearing Buddys we offer.
