Eagle Ford 351 Windsor 4.000in Stroke 2.100in Rod Journals Internal Balanced Forged Steel Crankshaft

Eagle is well-known for building strong rotating assemblies for performance engines. This Eagle forged 4340 steel crankshaft is designed for the Ford 351 Windsor engine, featuring a 4.000-inch stroke and 2.100-inch rod journals. It's internally balanced, meaning the counterweights are designed to balance the rotating assembly without the need for external balance weights, simplifying your build.

This crankshaft is constructed from forged 4340 steel, a material known for its exceptional strength and durability, making it suitable for demanding applications. It features a non-twist forging process for added rigidity and .125-inch fillet radii, which are chamfered or narrowed to accommodate specific bearing types and enhance overall strength. The surface is nitrided and then micropolished, a process that hardens the bearing surfaces for improved wear resistance and longevity, while the micropolishing ensures a smooth finish for reduced friction.

When installing this crankshaft, be aware that the .125-inch fillet radii require chamfered or narrowed bearings. Always refer to the manufacturer's installation instructions for detailed guidance on bearing selection, clearances, and assembly procedures to ensure optimal performance and durability for your engine build.
