Hello John. Not sure if you remember me but I happened to pick up that machined secondary from that fella on here. Running it in my Brute with big tires will it fail. We trail ride between mud hole and like the idea of the lighter weight. I do hit the mud aswell but usually allow time for the clutch to cool down while waiting for everyone. Also there was something about changing spring cups do I need to do that when I am putting it on my 2013 Brute.
