If you're building a naturally-aspirated LS engine for racing, a strong rotating assembly is the heart of your build. This Eagle Pro Street rotating assembly is designed to handle the demands of that kind of performance. It's a complete package that brings together the essential components needed to get your engine's bottom end rebuilt and ready for the track.

This assembly features a 3.900-inch stroke crankshaft, which is a key component that determines the displacement and power potential of your engine. Paired with the crankshaft are 6.125-inch I-beam connecting rods. I-beam rods are a popular choice for performance builds because they offer a good balance of strength and weight, making them suitable for high-RPM operation. The assembly also includes 3.820-inch pistons, which are sized to work with the crankshaft and connecting rods to achieve the desired engine displacement and compression ratio for your specific LS application. Eagle is known for producing well-built engine components, and this rotating assembly is no exception, offering a solid foundation for your performance LS project.
