About this part

Product Details

This Eagle Pro Street rotating assembly starts with a 3.900-inch stroke crankshaft, specifically designed for Chevy LS2 and LS3 engines. This is a well-built component for those looking to build a naturally-aspirated racing engine. The assembly includes 6.125-inch I-beam connecting rods and 4.030-inch pistons, forming the core of your engine's power delivery system.

Eagle has put together this rotating assembly with performance in mind. The I-beam connecting rods are a strong choice for racing applications, offering a good balance of strength and weight. The 4.030-inch pistons are sized to work with the crankshaft and rods, creating a complete package ready for assembly. This kit is intended for naturally-aspirated racing use, meaning it's optimized for engines that don't use forced induction like turbochargers or superchargers.

When building a high-performance engine, the rotating assembly is critical. This Eagle Pro Street assembly provides a solid foundation for your LS2 or LS3 build. Please note that this assembly is not CARB approved and cannot be shipped to California. Always consult with a professional engine builder or refer to manufacturer instructions for proper installation and balancing procedures.
