About this part

Product Details

Eagle is well-known for making strong internal engine components, and this Pro Street rotating assembly is a prime example of their work for Chevy LS1 engines. If you're building a naturally-aspirated racing engine, this assembly is designed to handle the demands of that kind of performance. It's a complete package that brings together the core rotating parts you need to get your LS1 engine built right.

This assembly features a 3.900-inch stroke crankshaft, which is a common choice for LS1 builds aiming for increased displacement and torque. Paired with it are 6.125-inch I-beam connecting rods. I-beam rods are a popular choice for their balance of strength and weight, making them suitable for many performance applications. The assembly also includes 3.913-inch pistons, which, when combined with the crankshaft and rods, will determine your final engine displacement. This specific crankshaft has a 58-tooth reluctor wheel, which is standard for most LS1 applications, ensuring compatibility with your engine's computer system. Everything here is built to be a solid foundation for a powerful, naturally-aspirated LS1 race engine.

When putting together a performance engine, the rotating assembly is critical. It's the heart of your engine's power output and durability. This Eagle Pro Street assembly gives you a well-matched set of components from a reputable manufacturer, simplifying your build process and giving you confidence in the parts you're installing. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or mechanic for specific installation requirements and any other components you might need to complete your engine build.
