Re: OEM VS. Aftermarket Bearings
DSMDUDE-The factory 4g63 CAST crank can be reground just fine. Re-nitriting is recommended, and the cast should work just fine. I have had personal experience with a few renitrated cranks that have been undercut and they work just fine.
Is a factory crank that isn't undercut nice? Yes, is it required, not always when on a budget.
