Eagle Chevy 409 4.000in Crank 6.135in H-Beam 89.1cc Dome 4.350in Pistons Balanced Assembly

If you're building a high-performance Chevy 409 engine, this balanced rotating assembly from Eagle is a solid foundation. It includes a 4.000-inch stroke crankshaft, 6.135-inch H-beam connecting rods, and 4.350-inch dome pistons, all balanced as a complete unit. This assembly is designed for those looking to maximize power and reliability in their classic Chevy V8.

Eagle has put together a well-built package here, featuring forged components for strength under demanding conditions. The H-beam connecting rods are known for their robust design, capable of handling significant horsepower. The dome pistons are specifically chosen to work with the 4.000-inch stroke and the 89.1cc combustion chamber volume, helping to achieve a desired compression ratio for performance applications. Having the assembly balanced from the factory means you're starting with a critical step already handled, reducing potential vibration issues and ensuring smoother engine operation.

This balanced rotating assembly is a significant component for a serious engine build. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to Eagle's specific installation guidelines to ensure proper fitment and assembly into your 409 engine block.
