Expert Reply:

For your 2017 trailer with Dexter 5200 lbs axles, there are two possible options for replacement bearing kits. Both kits, the # BK3-300 mentioned in your question and the # BK3-310, include an LM67048 outer bearing and 25580 inner bearing which match the hub and drum assemblies for your Dexter axle. The difference between the two kits is the inner diameter of the included grease seals.

The more likely fit for your trailer may be the # BK3-310 which has a smaller seal inner diameter and is usually associated with this sized bearing on your particular axle. The only way to know for sure though would be to measure the spindle on your trailer to confirm the grease seal will be the correct size. If you do not wish to do this, I recommend going with the bearing kit # BK3-310 but also purchasing separately the alternate grease seal size found in the other bearing kit, which will be part # RG06-070.

For reference I have included a helpful article about replacing bearings, races and seals on a trailer hub.
