K1 Billet Crankshafts Subaru EJ20 75mm stroke dual thrust
Wiseco and K1 Technologies have teamed up to bring you some of the best crankshafts available on the market today.
All crankshafts are 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 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.
