Expert Reply:

Yes, the Electric Trailer Brake Kit # AKEBRK-6 will fit your 12x2 AL-KO drums.

There are actually 2 different seals that are common among 5.2K - 7K axles like what you have. The first are the seals # RG06-070 which have the 2-1/4" ID and 3-3/8" OD like you mentioned. The second are the seals # RG06-090 which have a 2-1/8" ID and a 3-3/8" OD. The only ways to determine which is correct is to remove your hub/drums and see if you can find a part number on your current seals and/or use a digital caliper to measure your spindle to the 3rd decimal (1.234 for example) where the seal sits.
