Yea no doubt any crank can and does break. I just though there was a hot rod and wiseco epidemic that I missed. I do know that hot rods 4 mill cranks need rewelded. There stock stroke cranks are not even welded so that is a no brainer there. I am not slamming any body selling the crank. They are just giving you options, wich is nice to have.
My hot rods 4 mill origninated from crank works. It has a max load bearing on the stator side, and a tz bearing on the pto side, and has been rewelded.
