About this part

Product Details

This Eagle Pro Street rotating assembly starts with a 3.800-inch stroke crankshaft, built for the demands of naturally-aspirated racing applications. It's paired with 6.125-inch I-beam connecting rods, a well-known strong design for performance builds. The assembly includes 4.070-inch pistons, ready to be fitted into your Chevy LS2 or LS3 engine.

Eagle has a solid reputation for putting together robust rotating assemblies. This particular setup is designed for engines that rely on natural aspiration to make power, meaning it doesn't use forced induction like turbos or superchargers. The I-beam connecting rods offer a good balance of strength and weight, making them a popular choice for builders who want reliable performance without going to an extreme, heavy-duty design. The 4.070-inch piston size is specific to certain LS engine configurations, ensuring a proper fit and compression ratio when assembled correctly.

When building a performance engine, the rotating assembly is the heart of it all. This Eagle assembly gives you the core components needed to get your LS2 or LS3 engine breathing hard and making power. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed instructions for proper installation and balancing procedures to ensure the longevity and performance of your engine build.
