Eagle Chevy 502 4.250in Counterweight Crank 6.535in H-Beam 40cc 4.500in Pistons Rotating Assembly

This Eagle rotating assembly is built around a 4.250-inch forged 4340 steel crankshaft, featuring center counterweights. This design is crucial for balancing the forces within a high-performance engine, especially when dealing with the demands of exotic fuels, heavy nitrous use, or high boost applications. The crankshaft is paired with 6.535-inch H-beam connecting rods, known for their strength and reliability under stress. These rods are secured with 7/16-inch ARP L19 bolts, a strong choice for high-horsepower builds.

The pistons are forged 2618 aluminum from JE, featuring a 40cc dome and a 4.500-inch bore. This dome volume is designed to achieve specific compression ratios when paired with the right cylinder heads and crankshaft stroke. The assembly includes plasma-moly file-fit piston rings, allowing for precise gap setting to match your engine's bore and intended use. King XP series rod and main bearings are included, offering robust performance and durability for demanding conditions.

This heavy-duty rotating assembly is intended for competition engines pushing the limits. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer specifications for proper installation and compatibility with your specific engine build.
