Eagle 4G63 Stock Stroke 88mm Crankshaft

Built from a non-twist forging of 4340 steel, this Eagle crankshaft is ready to handle the demands of a performance 4G63 engine. The 88mm stock stroke is a direct replacement for your 1990-1992 Eagle Talon, Mitsubishi Eclipse, or Plymouth Laser, and it features a 6-bolt rear flange for compatibility with specific transmissions.

Eagle treats this crankshaft with a nitrided surface finish and a micropolished treatment for enhanced durability and reduced friction. The .125" fillet radii are designed for superior strength, but they do require the use of chamfered or narrowed bearings, so be sure to account for that during your build. This is a well-built component intended for serious engine builds where reliability is key.

When you're rebuilding the heart of your DSM (Diamond-Star Motors) vehicle, starting with a strong foundation like this forged crankshaft is crucial. It's designed to be a direct fit for the specified models, making the installation process as straightforward as possible, assuming you're already familiar with engine assembly procedures.
