Thanks for your question, Stefanie!
There aren’t any hub-and-drum assemblies rated specifically for 6.6K, so based on the info, it’s most likely that you have a 7K axle.
I'm not 100% certain on your wheel stud size, but for 7K axles, we typically see either 1/2" or 9/16" studs. Here are the two hub options based on each size:
1/2" studs – part # 42866UC3-EZ
9/16" studs – part # 8-219-13UC3
To go with those hubs, the matching electric brake kit would be part # 23-464-465. If you can confirm the stud size, I’ll be happy to make sure to get you set up with the right parts.
I'm curious what kind of trailer you have.

Hey Stefanie, did you manage to confirm the stud size for your axle and find the right parts? I'm asking because it could help others in a similar situation.
