Hello Nicole,

When I look at the brake assembly you found, the Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 12" - Right Hand - 7,000 lbs # 23-465 it tells me that you have a 7,000 pound axle, but I am going to need so more information in order to find you the right hub.

We unfortunately do not have a database that supplies me with what is put on what trailer (it would be pretty sweet if such a list existed), so I will need the following information:

- Bolt pattern
- Stud size
- Bearings

The common bolt pattern for the 7K axles is 8 on 6 1/2", but I will need you to confirm that is what you have. There are different bearing configurations for the 7K axles, so you will either need to take the bearings out to get the numbers off of them, or I attached an image that shows where to measure the spindle for the different bearing sizes.

My apologies that I cannot just supply you with the part numbers you requested without needing additional information from you. I look forward to hearing back from you so we can ensure we get you the correct hubs.

@Nicole That is most helpful, thanks Nicole. You will want the Dexter Trailer Hub and Drum Assembly for 5,200-lb to 7,000-lb E-Z Lube Axles - 12" - 8 on 6-1/2 # 8-219-4UC3-EZ. If you wanted to save some money, you could go with our etrailer hub # AKHD-865-7-2-EZ-K. Both hubs will come with new bearings and races.
