Eagle has a long history of making strong engine parts for performance applications. This rotating assembly is a prime example, designed to handle the demands of racing, whether you're running nitrous or boost. It’s a complete package built around a robust foundation for your Chevy 454 engine.

At the heart of this assembly is a 4.250-inch forged 4340 crankshaft, chosen for its strength and durability under high stress. Paired with this are 6.385-inch H-beam connecting rods, which are well-known for their ability to withstand significant loads. These rods come equipped with 7/16-inch ARP 8740 bolts, a popular choice for their reliability in high-performance builds. The pistons are forged 4032 ICON units, featuring a 23cc dome and a 4.250-inch bore size, designed to work seamlessly with the rest of the components. You also get plasma-moly file-fit rings, which allow for precise gap setting to optimize performance and sealing. Finally, the assembly includes King XP rod and main bearings, recognized for their advanced materials and ability to handle extreme pressures.

This is a comprehensive rotating assembly, meaning it includes the crankshaft, connecting rods, pistons, rings, and bearings. It’s a significant step up from stock components and is intended for serious performance builds. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
