Product Details
This Eagle Pro Street rotating assembly gives you a complete package for your Chevy LS2 or LS3 engine build. You get a 3.800-inch stroke crankshaft, 6.125-inch I-beam connecting rods, and 4.040-inch pistons, all balanced and ready to go. This assembly is specifically put together for naturally-aspirated racing applications, meaning it's designed to handle the demands of engines that don't use a turbocharger or supercharger.
Eagle has a solid reputation for building strong engine components, and this rotating assembly is no exception. The I-beam connecting rods are well-built for their intended use, offering a good balance of strength and weight for performance builds. The crankshaft is forged to handle the stresses of racing, and the pistons are sized for a 4.040-inch bore, common in many LS engine builds. This is a balanced assembly, which means the crankshaft, rods, and pistons have been precisely weighted and balanced together at the factory. This step is crucial for smooth engine operation and longevity, especially at higher RPMs. It's a significant time and labor saver compared to balancing components individually.
When you're putting together a performance engine, especially for racing, the rotating assembly is the heart of it all. This Eagle Pro Street assembly simplifies the process by providing a matched set of critical components. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure the best performance and durability for your build.
