Sadly them hot rod cranks are questionable as to their country of origin, or at least the box? Any oem bearing you can get an exact American bearing match, would last longer. Even the Japanese make better bearings than what goes in their bikes. There are different grades of bearings. Dare you to try some no name Chinese bearings? OEM is good enough. The wiseco cranks are nice looking. Never ran one, ran enough of their pistons. I have almost, always used hot rods when it came to bottom end over haul. Bearings and seals, you get what you pay for. That said, and the unique seals, I usually end up using oem for convenience. I went through a rash of cranks on a 93-95 cr80. For 60 dollars the oem crank is worth it? Well, that is about what I was paying for them junk cranks. Hindsight, I should have spent the extra money and went after market then also. I know a guy, who has claimed oem cranks come ten thousandths out of true, with regularity. That would guarantee loose fillings and a short engine life.You can have them checked, should anyways, then realigned? I swear I am going to true, weld, and balance my next crank job! For some models, they offer complete engine kits, a lot cheaper.
