Eagle Chrysler 360 4.000in Crank 6.123in H-Beam -20.5cc 4.040in Pistons Balanced Assembly

Eagle is well-known for building strong rotating assemblies that can handle serious power, and this balanced assembly is a prime example. If you're building a high-performance Chrysler 360 engine, especially one intended for racing, nitrous, or forced induction, this kit gives you the core components you need to get started. It’s designed to be a solid foundation for a powerful engine build.

This assembly features a 4.000-inch stroke crankshaft, paired with 6.123-inch H-beam connecting rods. H-beam rods are a popular choice for performance builds because they offer a strong, reliable design that can withstand higher cylinder pressures and RPMs compared to standard I-beam rods. The kit also includes 4.040-inch pistons with a -20.5cc dish, which helps achieve a specific compression ratio when combined with your cylinder heads and block. Everything in this assembly is balanced together, which is crucial for smooth engine operation at high RPMs and helps reduce overall engine vibration and stress on bearings.

This is a complete balanced rotating assembly, meaning the crankshaft, connecting rods, pistons, wrist pins, and rings are all balanced as a set. This saves you a significant step in the engine building process and ensures the critical rotating mass is properly balanced from the start. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and assembly procedures.
