Eagle Chevrolet LS Forged 4340 Steel Crank Long Snout 4.125 in Stroke - 58 Tooth Reluctor

This is the Eagle forged 4340 steel crankshaft, specifically designed for Chevrolet LS engines. It features a substantial 4.125-inch stroke, a long snout suitable for dry-sump oiling systems, and includes a 58-tooth reluctor wheel. This crankshaft is built for high-performance applications where strength and reliability are paramount.

Crafted from forged 4340 steel, this crankshaft starts with a non-twist forging process, ensuring maximum durability. The fillet radii are .125 inches, which are chamfered or narrowed to work with specific bearings, contributing to its superior strength. The surface is nitrided and then micropolished, a treatment that hardens the exterior while maintaining a smooth finish for reduced friction and wear. This level of attention to detail means it can handle the stresses of demanding engine builds.

This crankshaft fits a wide range of Chevrolet LS-based vehicles, including popular models like the Chevrolet Corvette (1997-2010), Chevrolet Camaro (1998-2002, 2010-2013), and Cadillac CTS (2004-2007). If you're building a high-output LS engine for racing, serious street performance, or a custom project, this forged crankshaft offers a solid foundation.
