Eagle Chevrolet LS 3.622in Stroke 24 Tooth Reluctor Forged 4140 Steel Crankshaft

This is the Eagle Chevrolet LS 3.622in Stroke 24 Tooth Reluctor Forged 4140 Steel Crankshaft, part number 534636226100. You're getting a forged 4140 steel crankshaft designed for Chevrolet LS engines with a 3.622-inch stroke and a 24-tooth reluctor wheel. This component is intended for competition use, meaning it's built to handle the demands of high-performance applications where durability and strength are paramount.

Eagle starts with a non-twist forging process for this crankshaft, which helps ensure its structural integrity under stress. The fillet radii are .125 inches, which are designed for superior strength. Because of these larger fillet radii, you will need chamfered or narrowed bearings when installing this crankshaft. The surface is then nitrided and micropolished. Nitriding is a heat-treating process that hardens the surface, making it more resistant to wear and fatigue, while micropolishing creates a very smooth finish for reduced friction and improved oil flow.

This crankshaft is a solid option if you're building a competition engine for your Chevrolet LS. It's important to ensure you have the correct bearings and understand the installation requirements for these specific fillet radii. Always refer to the manufacturer's installation guide for detailed procedures and specifications.
