The Eagle GM LS1 4340 Forged Crankshaft is the foundation for a reliable, high-horsepower LS build. Crafted from high-strength 4340 forged steel, this crankshaft is designed to withstand the rigors of forced induction, nitrous, or high-RPM naturally aspirated applications. With a 3.622-inch stroke, it offers the perfect balance of displacement and reliability for your GM LS-series engine.
Every Eagle forged crankshaft undergoes rigorous quality control to ensure precise journal dimensions and optimal oiling characteristics. The internal balance design reduces vibration and stress on your main bearings, extending the life of your engine build. Whether you are upgrading your daily driver or building a dedicated track machine, this crankshaft provides the durability needed to push your LS engine to the next level. The 4340 steel construction is significantly tougher than cast alternatives, providing a critical safety margin for high-output builds. Experience the difference in quality and performance when you source your engine internals from GGCRACING.
