Eagle Chevrolet 350 2Pc (Lightening Holes in No. 1 & No. 4) IMCA Legal Forged 4140 Steel Crankshaft

Forged from 4140 steel, this Eagle crankshaft is built to handle the demands of a high-performance Chevrolet 350 engine. The material choice means it's strong and durable, ready for serious builds. It features lightening holes in the #1 and #4 counterweights, a detail that helps reduce rotational mass without compromising the crankshaft's integrity. This specific design is also IMCA legal, making it a solid choice if you're building a race engine that needs to meet those regulations.

This is a two-piece rear main seal crankshaft, a common configuration for many Chevy 350 applications. The forging process itself creates a more uniform grain structure than casting, leading to a stronger and more reliable component. Eagle has a reputation for well-built rotating assemblies, and this crankshaft is no exception. It's designed to be a direct replacement for many 350 blocks, simplifying installation for your engine build.

When you're putting together a performance engine, the crankshaft is the heart of it all. Choosing a forged steel unit like this one from Eagle means you're starting with a robust foundation. It's ready for the stresses of increased horsepower and torque, whether you're building a street machine or a dedicated race car. Make sure to consult your engine builder or a trusted mechanic for specific installation requirements and balancing needs for your particular application.
