The Eagle 4G63 stroker crank for 1989–1992 Mitsubishi applications is a forged 4340 steel crank with a 94mm stroke and a 6‑bolt rear flange. Eagle’s forged cranks use a non‑twist forging process, .125" fillet radiuses for superior strength, nitriding and micropolishing. The unit is intended for demanding builds where a forged crankshaft is required to meet higher stress expectations.
