Eagle SBC 350 Forged Lightweight Crankshaft 3.480in Stroke 2.1in Rod Journal

Eagle is well-known for making strong engine components, and this forged 4340 steel crankshaft is a prime example. It's built for Chevrolet 305 and 350 cubic inch engines, featuring a 3.480-inch stroke and 2.1-inch rod journals. This crankshaft is designed to reduce rotating weight, making it a popular choice for restricted-class competition builds where every ounce counts.

The crankshaft starts as a non-twist forging from 4340 steel, which is a robust material known for its strength and durability. Eagle has incorporated a lightweight counterweight design to help lower the overall rotating mass of your engine. For added strength, it features .125-inch fillet radii, which means you'll need to use chamfered or narrowed bearings when installing this crank. The surface is nitrided and micropolished, processes that enhance its wear resistance and smooth operation.

This crankshaft fits a wide range of Chevrolet vehicles, including models like the 1969-1975 Chevrolet Bel Air, 1987-1994 Chevrolet Blazer, and the 1967-1993 Chevrolet Camaro, among many others. It's intended for competition use where performance and reliability are critical. When building or rebuilding your engine, especially for racing applications, this Eagle crankshaft offers a solid foundation.
