I hear you on the no adjustments making it fail faster.
Yet the clucth the factory put in these things has very little puck to them.
Messure both side as one and I bet its less than 1/4" thick.
The clutches we put in the bog trucks are near 3/8" thick each disck set. With them being duals this gives us 3/4" of pucks to have adjustments in it.
Thus why a beavy duty clutch will run half million miles and more.
