If you have a standard 10,000 lb trailer axle then you will need to use a 387A (2.250") inner bearing, 25580 (1.750") outer bearing, and a 10-51 (2.875") grease seal like what is included with the Dexter Trailer Hub and Drum Assembly part # 8-430-5UC3.

However, not all 10,000 lb trailer axles use the same bearings and seals therefore you will be wise to measure the spindle where the bearings and seals ride with a digital caliper like part # 301-17068 beforehand. The Electric Trailer Brake Kit part # AKEBRK-10 that you referenced is compatible with the Dexter Trailer Hub and Drum Assembly but you do need to make sure the trailer has a seven bolt brake mounting flange first.

The other option you have to confirm is by reading the axle number on the axle tag and calling the manufacturer.
