This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade the heart of your Chevy 4.8L or 5.3L LS engine. Inside this package, you'll find a precisely machined crankshaft with a 3.800-inch stroke, designed to handle the demands of naturally-aspirated racing applications.

Eagle has a solid reputation for building well-made engine components, and this rotating assembly is no exception. The Pro Street line is specifically geared towards naturally-aspirated racing use, meaning it's built with durability and performance in mind for applications where forced induction isn't being used. The I-beam connecting rods offer a strong balance of weight and rigidity, crucial for keeping your engine running smoothly under stress. The included pistons are sized to match the crankshaft and bore, ensuring a proper fit and optimal compression for your LS engine.
When undertaking an engine build of this caliber, it's important to ensure all components are balanced and installed correctly. This assembly is a significant step towards a powerful naturally-aspirated LS engine. Please note that this assembly is not CARB approved and cannot be shipped to California.
