How to Pick Out Replacement Hubs and Brake Assemblies for a Trailer

Published 07/02/2015

Question:

I have a roadrunner 8500# boat trailer with electric brakes 2 axles and 15 inch wheels. I want to replace them with a new electric brake assembly and a new hub. The numbers on the existing hub is 8-202-4G26 and says it is a 15245 cup? I dont see those numbers listed. What should I replace both the assembly and the hub with? Thanks,

The numbers you listed do not reference any of the parts that we carry but we can still help you get the replacement parts you need.

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 find the hub you need the correct brake assembly will be listed in the related parts on the product page of the hub.
