The hub part # 8-201-5UC3 is a 12 by 2 inch drum/hub that calls for a brake assembly that measures the same. The problem is that the 12x2 inch brake assemblies we carry are all 5-bolt flange assemblies.

It would be pretty unlikely that the hub you mentioned would be the correct fit for a spindle that only has a 4 bolt flange so I wonder if maybe you need a different hub actually.

In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out.

Next thing you will need to know is what spindle you have on your trailer. In order to do that you can either get the inner and outer bearing numbers from a hub or use a dial or digital caliper to get exact measurements of the spindle. The measurements needed are the parts of the spindle where the bearings ride.

If you get back to me with that information I will help you pick out the right hub assemblies. Or, you can follow the link I attached that will take you to the page that has all of our replacement hubs.

You would want to first select the bolt pattern that you have, next select the inner bearing you have, followed by selecting your outer bearing, and then all the correct hubs will be listed.

Once you pick out the hub you need in the related products section of the product page will be brake assemblies that will be properly rated and will fit.
