Eagle Chevy 502 1Pc 4.250in Counterwght Crank 6.385in H-Beam 37cc 4.500in Pistons Rotating Assembly

Eagle is well-known for building robust engine components, and this heavy-duty rotating assembly is a prime example, designed for the most demanding Chevy 502 applications. If you're building an engine for extreme competition, whether it's running exotic fuels, heavy nitrous, or high boost, this assembly is engineered to handle the stress.

At its core is a 4.250-inch forged 4340 steel crankshaft featuring center counterweighting, which helps to balance the assembly and reduce vibration under high RPMs. Connecting the crank to the pistons are 6.385-inch H-beam connecting rods, known for their strength and reliability in high-performance builds. These rods are secured with 7/16-inch ARP L19 bolts, a strong choice for high-stress applications. The assembly includes 4.500-inch forged 2618 JE pistons with a 37cc dome, designed for significant compression, and come with plasma-moly file-fit rings for good sealing. To ensure smooth operation and durability, the assembly is completed with King XP rod and main bearings, which are built for high-load conditions.

This rotating assembly is a substantial upgrade for any serious Chevy 502 build. Please note that this part is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
