Description
The Eagle forged 4340 steel crankshaft (Part Number: 2439375900A6) is engineered for high-performance automotive applications, particularly for Mitsubishi DSM models equipped with the 4G63 engine. Featuring a non-twist forging process, this crankshaft provides exceptional strength and durability, making it ideal for demanding street and racing environments. The crank’s design includes .125 inch fillet radiuses, which enhance fatigue resistance and overall structural integrity, although they require chamfered or narrowed bearings for proper installation. The surface is nitrided and micropolished, offering improved wear resistance and a smooth finish to reduce friction and extend part longevity.
