It is best to use a Digital Caliper # PTW80157 to determine the exact size of your hub bore to find the correct size cap. A 1.988" Cap # F001518 is the most commonly found size on current 2,000lb and 3,500lb axles. We do also have a couple Bearing Buddy protectors in a few other rare sizes you can use.

1.938" Hub Bore # BB1938SS
1.968" Hub Bore # BB1968SS
1.980" Hub Bore # BB1980A-SS

If none of these sizes will fit please let me know what size hub and bearings you have as I can recommend a replacement hub with the correct size caps.
