Product Details

If you're building a high-performance Chevy LS3 engine, a strong rotating assembly is the heart of your build. This Eagle rotating assembly is designed to handle the demands of a serious performance engine, providing a solid foundation for increased horsepower and torque. It includes a forged crankshaft, connecting rods, and pistons, all balanced and ready to be installed.

The core of this assembly is Eagle's 4.000-inch stroke forged crankshaft, known for its durability under stress. Paired with 6.125-inch H-beam connecting rods, these components are built to withstand the higher cylinder pressures and RPMs common in performance applications. The assembly also features -25cc dish pistons with a 4.075-inch bore, designed to work with a 24-tooth reluctor wheel common in many LS3 applications. This combination helps achieve a specific compression ratio suitable for many performance builds, though it's important to verify compatibility with your specific cylinder heads and camshaft choice.

This rotating assembly comes balanced from Eagle, saving you a significant step and ensuring proper engine operation. While this assembly is built for performance, please note it is not CARB approved and cannot be shipped to California. For a complete engine build, ensure you have all necessary supporting components like bearings, gaskets, and a quality oiling system.
