Wiseco Crankshaftsare 4340 steel, core hardened and tempered to reduce stress and optimize tensile strength. The crankshafts are made with a nitriding process for hardening rather than induction heat treated. This eliminates any softening between the journals and any post running deformation. Our crankshafts also feature straight oil holes for the best oiling to the rod journals to insure you get the best crank for your money. Each K1 crankshaft is magnetic particle inspected and held to a maximum tolerance of .0002 journal dimension. Counterweights are placed for optimal load reduction and ease of balancing making less work for you or your builder.
