Hello Gregory, thanks for reaching out. We should have what you need, but there is no way to look up your trailer to know exactly what bearings your trailer uses. Trailer manufacturers just are not that specific with their online literature.

That said, it should still be pretty easy to determine what you need. The best way to do this is to find the casting number on your hub. Idler hubs will have a number cast on the back, while drums will have a number on the front. Get me that number and I should be able to use that to know what bearings you need.

Or if you can find the axle tag/sticker and find the weight capacity that will help to narrow things down.

For example, 3,500 lb axles use a standard bearing combination, and the kit for that is part # BK2-100.

Get me that hub number and I am happy to look into it.
