Eagle Chevrolet 305/350 4.000in Stroke 2.000in Rod Journals Forged 4340 Lightweight Steel Crankshaft

Eagle is well-known for making strong engine components, and this forged 4340 steel crankshaft is a prime example of their work. This particular crankshaft is built for Chevrolet 305 and 350 engines, featuring a 4.000-inch stroke and 2.000-inch rod journals. It's designed with a non-twist forging and a lightweight counterweight design to help reduce rotating weight in your engine, which can lead to improved performance.

The construction here is serious business. It's made from forged 4340 steel, a material chosen for its strength and reliability under demanding conditions. Eagle has also incorporated .125-inch fillet radii, which significantly boosts strength. Because of these larger radii, you'll need to use chamfered or narrowed bearings when installing this crankshaft. The surface is nitrided and then micropolished, further enhancing its durability and smooth operation. This crankshaft is intended for restricted-class competition use, meaning it's built to handle the stresses of racing where specific classes have limitations.

When building a competition engine, every component matters, and this Eagle crankshaft is designed to be a solid foundation. Its lightweight design and robust construction are key features for anyone looking to optimize their engine for performance in a restricted class. Remember to source the correct chamfered or narrowed bearings to ensure proper fitment and function with this crankshaft.
