Manley Mitsubishi 4G63/4G64 7 Bolt 4340 Forged 88mm Stroke Race Series Crankshaft

When you're building a high-horsepower, high-boost engine for your Mitsubishi or Eagle vehicle, you need a crankshaft that can handle the stress. This Manley Race Series crankshaft is forged from 4340 "Turbo-Tuff" billet material, giving you the durability and performance required for demanding applications. It's designed to increase displacement, offering a 9.3% increase over stock with its 94mm stroke, which translates to more power potential.

Manley puts these crankshafts through a multi-step heat treatment process and nitriding to significantly enhance their strength and longevity. To ensure precise balance and stability, the counterweights are fully knife-edged. Before they leave the factory, each crankshaft undergoes stress relief, shot peening, and 100% magnafluxing to meet Manley's strict quality standards. This level of attention to detail means you're getting a well-built component ready for serious performance.

This crankshaft fits a range of vehicles, including the Mitsubishi Eclipse, Lancer, and Galant, as well as the Eagle Talon. It's a solid option for anyone looking to push the limits of their 4G63 or 4G64 7-bolt engine. Remember to consult your engine builder or service manual for specific installation procedures and recommended components to complete your build.
