Eagle 4G63 Stroker 100mm Crankshaft For 7-Bolt (Evo)

Starting with a forged 4340 steel construction, this Eagle crankshaft is built for serious performance. It features a 100mm stroke, which is a significant increase over stock, allowing for a larger displacement and more power potential in your 4G63 engine. The non-twist forging process ensures the crankshaft maintains its integrity under high stress, while the .125" fillet radii are chamfered to accommodate narrowed bearings, further strengthening the critical journal areas.

This crankshaft also undergoes a nitriding surface treatment and micropolishing. Nitriding hardens the surface, making it more resistant to wear and fatigue, which is crucial for a component that spins at high RPMs. Micropolishing refines the surface finish of the journals, reducing friction and improving oil flow, which helps keep the bearings cool and extends their life. This crankshaft is specifically designed for the 7-bolt rear flange configuration found in many performance Mitsubishi and related platforms.

When you're building a high-performance engine, the crankshaft is the backbone. This Eagle stroker crankshaft is a well-built component intended for those pushing their engines to the limit. It's designed to handle the increased demands of a stroker setup, providing a solid foundation for your build. Ensure you use the appropriate narrowed bearings and follow manufacturer guidelines for installation to get the most out of this performance crankshaft.
