Eagle Chevy 454 1Pc 4.250in Counterwght Crank 6.385in H-Beam 44cc 4.310in Pistons Rotating Assembly

Starting with a forged 4340 center counterweighted crankshaft measuring 4.250 inches, this Eagle rotating assembly is built for serious performance in Chevy 454 engines. This isn't just a collection of parts; it's a balanced system designed to handle the demands of extreme competition, including exotic fuels, heavy nitrous use, and high boost applications. The crankshaft's center counterweight design helps to reduce vibration and improve balance, which is crucial when you're pushing an engine to its limits.

Complementing the robust crankshaft are 6.385-inch H-beam connecting rods, known for their strength and reliability under high stress. These rods are secured with 7/16-inch ARP L19 bolts, a material chosen for its exceptional tensile strength and resistance to stretching, ensuring a solid connection between the rod and crank. The assembly also features forged 2618 JE pistons with a 44cc dome and a 4.310-inch bore size, paired with plasma-moly file-fit rings. This piston and ring combination is designed for optimal sealing and performance in high-compression, high-stress environments. King XP rod and main bearings are included, providing durable and reliable lubrication surfaces for the rotating assembly.

This rotating assembly is a well-built foundation for a high-performance engine build. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and tuning procedures to get the most out of this heavy-duty rotating assembly.
