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

When you're building a high-horsepower, high-boost Mitsubishi 4G63 or 4G64 engine, you need a crankshaft that can handle the stress. This Manley Performance Race Series crankshaft is forged from 4340 billet material, known for its exceptional durability and performance under extreme conditions. It's a fully machined component designed to be the backbone of a serious engine build.

This crankshaft features an 88mm stroke, which is a notable increase over the stock dimension. This longer stroke effectively increases your engine's displacement, leading to more power potential. To ensure it can withstand the demands of boosted applications, Manley puts this crank through a multi-step heat treatment process and nitriding, which significantly enhances its strength and longevity. The counterweights are also knife-edged for precise balancing and stability, crucial for high-RPM operation. Every Manley crankshaft undergoes rigorous quality assurance, including stress relief, shot peening, and 100% magnafluxing, to meet their strict standards.

This crankshaft is a key component for anyone looking to push the limits of their 4G63 or 4G64 engine. It's designed for serious performance builds where reliability and strength are paramount. Ensure you have the necessary supporting components and expertise for installation, as this is a critical engine part.
