What you get in this balanced rotating assembly is a complete package designed to get your Chevy 409 engine running strong. Inside this box, you'll find a 4.000-inch stroke crankshaft, 6.135-inch I-beam connecting rods, and 4.342-inch dome pistons. This assembly is precision balanced at the factory, meaning it's ready to install right out of the crate, saving you time and the cost of external balancing services. This is a significant upgrade for anyone rebuilding or building a high-performance 409 engine.

Eagle is known for putting together solid rotating assemblies, and this one is no exception. The I-beam connecting rods are a strong choice for performance applications, offering a good balance of strength and weight. The dome pistons are designed to work with specific cylinder head configurations to achieve a desired compression ratio, crucial for optimizing power output. Having the entire assembly balanced from the start is a big deal; it reduces vibration, allows the engine to rev more freely, and puts less stress on bearings and other internal components over time. This balanced approach is key to building a reliable, high-revving engine.

When you're putting together a serious engine build, starting with a balanced rotating assembly like this Eagle package simplifies the process and ensures a strong foundation. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to your engine build specifications and manufacturer instructions for proper installation and compatibility with other engine components.
