Question:
I have a 2018 Big Tex 25GN. I believe the brakes I need are the electric 12.25x 5. I would like just the brake setup with new races and seals i believe. Do you have that option or is it just either the brakes or whole kit? Thanks!

Thanks for your question, Isaac!
We do have just those parts by themselves so you dont have to get a whole new hub/drum if you're not needing one.
Here are all the parts:
Pair of electric brakes - part # KEBRK-12
Inner race - part # 3920 (matching bearing is part # 3984)
Outer race - part # 28622 (matching bearing is part # 28682)
Seal - part # 10-56
You don't have to replace the bearings but I really do think that it would be a good idea to since you will have everything apart that way you know everything in the hub is new.
Are you working on a tune up on your trailer?
