Fits 1990-1992 Eagle Talon TSi, Mitsubishi Eclipse GS/GSX, and Plymouth Laser RS (4G63).

The Eagle 2034655900A6 forged 4340 steel crankshaft is engineered for the high-stress demands of performance 4G63 engines. Utilizing a non-twist forging process, this stock 88mm stroke crank offers superior structural integrity and grain flow compared to cast alternatives. The journals are nitrided for increased surface hardness and micropolished for reduced friction and extended bearing life.

This crankshaft features .125-inch fillet radii to improve strength and fatigue resistance at the rod and main journals. Please note that due to these larger radii, chamfered or narrowed performance bearings are required for proper clearance and installation during the assembly process.
