looks like someone might have finally came up with the cure to the crank bearing failures? im guessing that you would have to drill and tap the cases but its basically the holders for the other bearings in the engine

The stock clips can break and create a huge mess in your engine , it happened to a friend of mine , the clip broke and went right in the case , and the crank was touching it so there was a really strange noise in the engine , he stopped , got the motor in pieces and found the clip in the case.

So i think these are stronger and can prevent this from happening , and they fit right in the stock cases.
