Eagle Chevy 454 4.000in Crank 6.135in H-Beam 18.3cc Dome 4.320in Pistons Balanced Assembly

Eagle is well-known for building strong rotating assemblies that hold up to serious use. This balanced assembly is built for Chevy 454 engines and is ready for demanding applications, including racing with nitrous or forced induction. It's a complete package designed to give your engine a solid foundation for high performance.

At the heart of this assembly is a forged 4340 steel crankshaft with a 4.000-inch stroke. Paired with it are 6.135-inch H-beam connecting rods, which are known for their strength and reliability under stress. These rods use 7/16-inch ARP 8740 bolts, a popular choice for their durability. The pistons are forged 4032 aluminum from ICON, featuring an 18.3cc closed chamber dome design and a 4.320-inch bore size. This assembly also includes plasma-moly file-fit piston rings, which allow for precise gap setting to match your specific engine build. For the bearings, King XP rod and main bearings are included, offering excellent performance and wear resistance.

This is a fully balanced rotating assembly, meaning the crank, rods, pistons, rings, and bearings have been precisely balanced at the factory. This reduces vibration and stress on your engine's main bearings and overall structure, which is crucial for longevity, especially in high-RPM applications. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
