Eagle Chrysler Hemi 3.750in Stroke 8 Bolt H-Beam 6.860in Pistons 4.310in Bore Balanced Assembly

Eagle is well-known for making strong internal engine components, and this balanced rotating assembly is a prime example of their work for Chrysler Hemi engines. If you're building a performance Hemi or refreshing a tired one, this assembly gives you a solid foundation to work from. It includes a crankshaft, connecting rods, and pistons, all balanced together to reduce engine vibration and improve overall smoothness.

This assembly features a 3.750-inch stroke crankshaft, which is a common choice for increasing displacement and torque in Hemi engines. The connecting rods are Eagle's popular H-beam design, known for their strength and ability to handle higher horsepower applications. They measure 6.860 inches long, a spec often chosen to optimize piston speed and rod angle for better performance. The pistons are sized for a 4.310-inch bore, and the entire package is balanced as a unit. This balancing is crucial because it ensures the rotating assembly spins true, reducing stress on bearings and the engine block, which is especially important in high-performance builds.

When you're putting together a serious Hemi engine, starting with a balanced rotating assembly like this one saves you time and ensures a critical aspect of the build is done right from the start. It's designed to be a complete rotating assembly, meaning the key moving parts are matched and balanced together. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified mechanic for specific installation requirements and compatibility with your particular Hemi engine build.
