Chrome crankshaft

I am trying to find a place to get my crankshaft hard chromed. Anyone know of a place? Seems like all the places that used to do it are now out of business for EPA reasons. I am located just south of Indy, but won't mind shipping it if I absolutely have to.

Input is appreciated,
Thanks

Give these guys a try. Not sure if that is the best thing any more for a crank.

See this blog. It doesn't look like the way to go.

Call Marine Crankshaft Inc. If you google it, thier the first one to come up. They can do anything with a crank, they can advise you if chroming is the best thing.

wow thanks for that info guys. I had no idea. Two established racers over here introduced me to it, however it was never explained why. From reading that thread, at $600 a hard chrome plus original cost of crank, it would be smarter to just purchase a real nice one and be done with it.

Thanks again for the input.

You used to hard chrome a crank for just that reason. The chrome was harder than the steel (bigger Brinell number). About the only people that still use a hard chromed crank are off road endurance racers (Baja open desert type where there is a greater probability of grit getting into the oil). Drag racers and NASCAR types are all using a nitrided surface instead and then freezing the crank a few times in liquid nitrogen to stress relieve the journal surfaces to rid them of all micro cracks.
