Fits select 1993-2006 Mitsubishi Eclipse and Lancer Evolution, Eagle Talon, and Plymouth Laser (7-bolt 4G63).

Engineered for high-stress racing and street applications, the Eagle forged 4340 steel crankshaft offers exceptional durability for 7-bolt 4G63 engines. This crankshaft is manufactured using a non-twist forging process and features a nitrided surface for superior wear resistance. Every journal is micropolished to ensure optimal oil film thickness and reduced friction during high-RPM operation.

This stock stroke 88mm crank is designed with .125" fillet radii to significantly increase strength and prevent fatigue at the journal transitions. Due to this design, narrowed or chamfered high-performance bearings are required for proper installation and clearance.
