Eagle Chevy Small Journal 283-327 Stock Stroke Forged 4340 Chromoly Crankshaft

Eagle has built a reputation for making well-built performance engine parts. This forged 4340 chromoly crankshaft is designed for Chevrolet small journal 283 through 327 engines, specifically for builds that demand a lot from the engine. It's built to handle the stress of high-performance applications.

This crankshaft starts as a non-twist forging made from 4340 chromoly steel, which is a strong material known for its durability. The fillet radii are .125 inches, which adds to its strength, but it means you'll need to use chamfered or narrowed bearings. The surface is nitrided and then micropolished. Nitriding hardens the surface to resist wear, while micropolishing ensures a smooth finish for reduced friction and better oil flow.

This is a stock stroke crankshaft, meaning it maintains the original stroke length for your engine. If you're rebuilding a high-performance small block Chevy and need a crankshaft that can stand up to serious use, this Eagle forged unit is a solid option. Remember to use the correct chamfered or narrowed bearings to match the .125" fillet radii for optimal performance and longevity.
