Oh there's plenty wrong with the stock chain. It's a piece of ****. There's just nothing you can do to make them stronger other than tossing them in the trash can and converting to a single wide chain to start with. It's not that pricey of an upgrade really, if you can't afford to go to a single chain then you can't afford to make enough power to need one. If your making big power you have to start looking for the big boy GMR drive chain parts but there are only few that make it that far.
the standard upgrade "7/8ths" 4t60 single chain suits most of us well enough
