Eagle Chrys Hemi 3.750in Strk 8 Bolt Flng H-Beam 6.860in 112cc Dome Piston 4.280in Bore Bal Assembly

If you're building a high-performance Chrysler Hemi engine, getting the rotating assembly right is crucial for power and reliability. This balanced rotating assembly from Eagle is designed to handle the demands of a serious build, featuring a 3.750-inch stroke crankshaft and robust H-beam connecting rods. The 8-bolt flange ensures a strong connection for the flywheel or flexplate, a detail often overlooked but vital for durability under stress.

This assembly includes 112cc dome pistons, which are key for achieving a desired compression ratio in many Hemi applications, especially when paired with specific cylinder heads. The pistons are designed to work with a 4.280-inch bore, and the entire assembly is balanced from the factory. This balancing is a significant time and labor saver during engine assembly, ensuring smoother operation and reducing vibration at high RPMs. Eagle is known for producing well-built internal engine components, and this rotating assembly reflects that reputation, using strong materials to withstand the forces generated in a performance Hemi.

When assembling your Hemi, pay close attention to bearing clearances and ring gap settings as per the piston manufacturer's recommendations. This balanced rotating assembly is a solid foundation for your project, but remember it is not CARB approved and cannot be shipped to California. Ensure you have the correct cylinder heads and camshaft to complement the compression ratio and displacement this assembly creates.
