Eagle Chevrolet Small Block Internally Balanced 3.625in Stroke 4340 Crankshaft

This is an Eagle forged 4340 steel crankshaft, specifically designed for Chevrolet 305 and 350 small block engines. It features an internally balanced design and a 3.625-inch stroke, making it a solid choice for performance builds where increased displacement and power are key goals. The non-twist forging process ensures the crankshaft maintains its integrity under high stress.

Eagle uses 4340 steel for its strength and durability, and this crankshaft is further enhanced with a nitrided surface treatment and micropolishing. The .125-inch fillet radii are designed for superior strength, but it's important to note that these require chamfered or narrowed bearings to properly fit. This attention to detail in the forging and finishing processes means you're getting a well-built component ready for serious work.

When you're building a performance engine, the crankshaft is the heart of it all. This Eagle crankshaft is intended for demanding applications, offering a strong foundation for your project. Ensure you have the correct chamfered or narrowed bearings on hand for installation, as they are necessary due to the crankshaft's fillet radius design.
