Eagle Chrysler RB 8 Bolt 4.150in Crank 6.760in H-Beam -29cc 4.375in Pistons Balanced Assembly

This Eagle Competition Rotating Assembly starts with a robust 4.150-inch stroke crankshaft, designed for serious performance applications. It's built around a strong 8-bolt flange pattern, ensuring a solid connection for your flywheel or flexplate, and features 6.760-inch H-beam connecting rods. These rods are well-known for their strength and ability to handle high RPMs and significant cylinder pressures, making them a popular choice for builds that see a lot of abuse.

The assembly includes 4.375-inch pistons with a -29cc dish, which helps achieve a specific compression ratio when paired with your cylinder heads. Everything in this kit is balanced as a complete rotating assembly. This balancing is crucial because it reduces engine vibration and stress on bearings, leading to a smoother running engine and potentially longer component life, especially under demanding racing conditions like nitrous or forced induction use. This is a well-built package for those pushing the limits of their RB engine.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's intended for racing use where emissions compliance is not a factor. Ensure you have the correct supporting components for your specific RB engine build to properly install and utilize this high-performance rotating assembly.
