About this part

Product Details

If you're building a high-performance Chevy LS3 engine for competition, a robust rotating assembly is the heart of your build. This Eagle rotating assembly is designed to handle the demands of serious power. It includes a 4.125-inch stroke crankshaft, 6.125-inch H-beam connecting rods, and 4.030-inch pistons, all balanced and ready to go for your project.

The crankshaft is forged from high-quality steel for strength and durability, featuring a 4.125-inch stroke to increase displacement and potential power output. The 6.125-inch H-beam connecting rods are well-built to withstand high RPMs and significant cylinder pressures, a common requirement in competition engines. Paired with 4.030-inch pistons, this assembly is designed for a 4.030-inch bore, allowing for a substantial engine displacement. The assembly also includes a 58-tooth reluctor wheel, essential for proper engine management system communication on many LS applications.

This rotating assembly is a popular choice for engine builders looking for a strong foundation for their LS3 builds. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to manufacturer instructions for proper installation and balancing procedures to ensure optimal performance and longevity.
