Eagle Chrysler Hemi 4.150in Stroke 8 Bolt H-Beam 6.860in Pistons 4.290in Bore Balanced Assembly

What you get in this balanced rotating assembly is a complete package designed to form the heart of your Chrysler Hemi engine. This assembly includes a crankshaft with a 4.150-inch stroke, H-beam connecting rods that are 6.860 inches long, and pistons sized for a 4.290-inch bore. It's all balanced together, meaning the rotating mass is precisely weighted to reduce vibration and improve engine smoothness right from the start.

Eagle is known for building robust rotating assemblies, and this one is no exception. The H-beam connecting rods are a strong choice for performance applications, offering a good balance of strength and weight. The crankshaft is forged, which is crucial for handling the stresses of a high-performance Hemi engine. The pistons are designed to work with this specific bore size and stroke, ensuring proper compression and combustion chamber volume. Having the assembly balanced from the factory saves you a significant step and ensures the critical rotating components are in harmony, which is essential for engine longevity and performance, especially when you're pushing the limits.

This assembly is a substantial upgrade for anyone rebuilding or building a performance Hemi. Because it's a balanced rotating assembly, it's ready to be installed into your engine block after you've prepared it. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer documentation for specific installation procedures and any additional components you might need for your build.
