About this part

Product Details

Eagle is well-known for building strong internal engine components, and this Pro Street rotating assembly is a prime example of their work for Chevy LS2 and LS3 engines. If you're building a naturally-aspirated racing engine, this assembly is designed to handle the demands of that kind of performance. It includes a 3.900-inch crankshaft, 6.125-inch I-beam connecting rods, and 4.000-inch pistons, all balanced and ready to go.

This assembly is put together with performance in mind. The I-beam connecting rods are a solid choice for racing applications, offering a good balance of strength and weight. The crankshaft is forged from durable material, built to withstand the stresses of high RPM and significant cylinder pressures that come with naturally-aspirated racing. The included pistons are sized to match the bore and stroke, creating a complete package that's ready for installation. This is a well-built rotating assembly that gives you a strong foundation for your performance LS engine build.

When you're putting together a serious racing engine, the rotating assembly is one of the most critical parts. This Eagle Pro Street assembly gives you the confidence of a balanced, matched set of components from a reputable manufacturer. 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 balancing, assembly, and break-in procedures to ensure the longevity and performance of your engine.
