These are the closest to OEM that I could find. They install very similar to OEM. Some cheaper seals slide right on, these guys take some patience and know how to install. Over all I am very impressed!
I replaced these in my YZ and they blew out after an hour of riding. And I mean 'oil blowing out of the seal' blew out.
Get tusk seals because they are made by the same company as Factory Connection and work excellent.
