Eagle Chevy LS1 24 Tooth Reluctor 4140 Chromoly Forged Crankshaft

Eagle is well-known for building strong engine components, and this 4340 chromoly forged crankshaft is a prime example. If you're working on a Chevy LS1 engine, this crankshaft is built to handle serious power. It features a 4.125-inch stroke, giving your engine more displacement and potential for increased torque and horsepower.

This crankshaft starts as a non-twist forging made from 4340 steel, which is then treated with a nitrided surface and micropolished finish for added durability and smooth operation. The .125-inch fillet radii are designed for superior strength, though they do require chamfered or narrowed bearings. It also includes a 24-tooth reluctor wheel, essential for the engine's computer to accurately read crankshaft position.

This crankshaft fits a range of popular vehicles, including models like the Cadillac CTS, Chevrolet Camaro, and Pontiac GTO. It's a solid choice for builds where reliability and strength are paramount. When installing, be sure to use the appropriate bearings that match the fillet radius specifications.
