Nope. They were nodular iron. Either that or Forged steel. Mopar never offered the cast steel shafts from the factory. Mopar Performance did as an aftermarket piece. I think they were made by Eagle. The Cleveland cranks I am talking about were box stock. THey may have had some fancy machine work done like fillet radii and knife edging, but they were the stock pieces. You are correct that there were aftermarket pieces available, but I am not talking about those here.
