The 58mm crankshaft is made of ductile iron. Ductile is the ability to bend or flex before breaking. The ductile iron has superior shock absorption and higher fatigue strength performance over the lesser cast crankshaft. The 58mm or 2.283" stroke is a great way to stroke your clone or predator without spending a fortune on billet crankshafts. The crankpin and journals are hardened to reduce wear and increase the strength of the crankshaft.

ARC Clone Rod works with the crankpins but may require clearance to fit the block and not interfere with the camshaft. Therefore, this is not a drop-in solution but requires an experienced engine builder to assemble.
