Try this site for some info, the best a person could do is a little research under "US made Crankshafts"
This reminds me of when the US started buying billet steel from Japan, They were selling it as quality steel to us to machine, well on many occassions while cutting this steel on a lathe you would come across a hard section that would about tear your tool off the machine, turned out to be ball bearings thrown into the mix and then exported to the US as quality metal.
Of late you can buy tools from china that either shatters due to being to brittle or just plane breaks after a few uses.
I have old plumb, proto, snap on & even crafts man older tools that have survived many jobs that I would not even think of putting a chinese tool threw.
Same goes for cranks! No chinese made crank will ever see it's way into my Pantera or anything else, to damn important!
