Product Details

If you're building a high-performance naturally-aspirated LS7 engine for racing, a solid rotating assembly is the heart of your build. This Eagle Pro Street rotating assembly is designed to handle the demands of serious competition, providing a strong foundation for your engine's power output. It's a complete package that brings together the essential components for your LS7's bottom end, ensuring they work together harmoniously.

This assembly features a 3.900-inch stroke crankshaft, which is a key component in determining your engine's displacement and torque characteristics. Paired with it are 6.125-inch I-beam connecting rods, known for their strength and reliability in performance applications. The assembly also includes 4.125-inch pistons, completing the set for your LS7 build. The 24-tooth reluctor wheel is standard for many LS applications, ensuring compatibility with your engine's computer system.

When assembling a performance engine, ensuring all rotating components are balanced is critical for longevity and smooth operation.

Also, please note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always consult your local regulations regarding engine modifications.
