Eagle Chevrolet 305/350 3.500in Stroke Forged 4340 Steel Lightweight Crankshaft

If you're building a high-performance Chevrolet 305 or 350 engine for competition, a strong and lightweight crankshaft is crucial. This forged 4340 steel crankshaft from Eagle is designed to handle the demands of restricted-class racing, offering a significant advantage by reducing rotating weight.

Eagle starts with a non-twist forging of 4340 steel, known for its excellent strength and durability. This crankshaft features a lightweight counterweight design, which directly translates to quicker engine response and less stress on other rotating assembly components. The .125" fillet radii are intentionally designed for superior strength, meaning you'll need to use chamfered or narrowed bearings to ensure proper fitment. For added durability and a smooth surface finish, the crankshaft is nitrided and then micropolished. This process helps to improve wear resistance and reduce friction.

This crankshaft is intended for restricted-class competition use, where every ounce of weight savings and every bit of strength counts. It's a well-built component designed to be the foundation of a powerful racing engine.
