Eagle Chevrolet LS 4340 3.800in Stroke 24 Tooth Reluctor Forged Crankshaft

If you're building a high-performance Chevrolet LS engine and need a solid foundation, this Eagle forged 4340 steel crankshaft is a strong contender. It's designed with a 3.800-inch stroke, which is a common choice for increasing displacement and power in LS applications. This crankshaft also comes equipped with a 24-tooth reluctor wheel, essential for proper engine management system operation on most modern LS engines.

Eagle starts with a non-twist forging of 4340 steel, a material known for its excellent strength and durability, making it well-suited for demanding builds. To further enhance its robustness, the fillet radii are .125 inches, which are chamfered or narrowed to accommodate specific bearing types and provide superior strength. The surface of the crankshaft is nitrided for increased hardness and wear resistance, and then micropolished to ensure smooth operation and optimal bearing life. This level of attention to detail means it's built to handle significant power and stress.

This crankshaft is intended for serious engine builds where reliability and performance under load are critical. When installing, be aware that the .125" fillet radii require the use of chamfered or narrowed bearings, so make sure you select the correct ones for your build. This component is a key piece for anyone looking to push the limits of their LS engine.
