About this part

Product Details

If you're building a high-performance naturally-aspirated LS engine for racing, a strong rotating assembly is the heart of the operation. This Eagle Pro Street rotating assembly is designed to handle the demands of serious competition, providing a solid foundation for your LS2 or LS3 build. It brings together a precisely balanced crankshaft, robust connecting rods, and quality pistons to ensure reliable power delivery when you need it most.

At the core of this assembly is a 3.900-inch stroke crankshaft, paired with 6.125-inch I-beam connecting rods. These I-beam rods are well-built for their intended application, offering a good balance of strength and weight for racing use. The assembly also includes 4.005-inch pistons, completing the critical components that form the power-making heart of your engine. Eagle has a reputation for putting together reliable rotating assemblies, and this Pro Street package is a popular choice for those looking to maximize performance from their LS engine without forced induction.

This assembly is intended for racing applications and is not CARB approved, meaning it cannot be shipped to California. Ensure you have the necessary supporting components and expertise for installation, as a balanced rotating assembly requires careful attention to detail during the build process. Refer to the manufacturer's installation instructions for specific guidelines and torque specifications.
