Eagle Chevrolet 350 2Pc 3.480in Stroke IMCA Legal Forged 4340 Steel Crankshaft

Eagle is a well-known name for performance engine parts, and they've built a reputation for making robust components that hold up under demanding conditions. This particular crankshaft is forged from 4340 steel, a strong material chosen for its ability to handle high stress and heat, making it a solid choice for serious engine builds. It's specifically designed with a 3.480-inch stroke, which is a common measurement for Chevrolet 350 engines, and it meets IMCA legal requirements for the RaceSaver series, meaning it's ready for the track right out of the box.

What sets this Eagle crankshaft apart is its construction details. It features a non-twist forging process for added strength and .125-inch fillet radii. These radiuses are narrowed, so you'll need chamfered or narrowed bearings to go with it, which is a practical detail to keep in mind during your build. The surface is nitrided and then micropolished, a treatment that hardens the steel and creates a smooth finish for reduced friction and improved wear resistance. You won't find lightening holes in the second or third rod throws, further contributing to its overall strength and durability for racing applications.

When you're putting together a performance engine, especially for racing, the crankshaft is the backbone. This Eagle forged 4340 steel crankshaft is built to be a reliable foundation for your Chevrolet 350 build. Remember to source the correct chamfered or narrowed bearings to ensure proper installation and optimal performance.
