Eagle Chevy 502 4.250in Counterweight Crank 6.535in H-Beam 46cc 4.625in Pistons Rotating Assembly

If you're building a high-performance Chevy 502 engine for serious competition, a robust rotating assembly is the heart of the operation. This Eagle Heavy Duty Rotating Assembly is designed to handle the most demanding conditions, whether you're running exotic fuels, heavy nitrous, or high boost applications. It's a well-built foundation for an engine that needs to perform under extreme stress.

This assembly starts with a 4.250-inch forged 4340 steel crankshaft, featuring center counterweighting for improved balance and reduced vibration at high RPMs. Paired with this are 6.535-inch H-beam connecting rods, known for their strength and reliability, secured with 7/16-inch ARP L19 bolts. The pistons are forged 2618 JE units, sized at 4.625 inches with a 46cc dome and gas porting, designed to work with your cylinder head volume. The assembly also includes plasma-moly file-fit piston rings, which allow for precise gap setting to match your engine's bore and intended use, and King XP rod and main bearings for smooth operation and durability.

When assembling a high-output engine like this, attention to detail is crucial. The file-fit rings mean you'll need to set the end gap yourself, which is standard practice for performance builds to ensure proper sealing and prevent piston slap. This rotating assembly is a solid option for anyone pushing the limits of their Chevy 502 engine, providing the strength and precision needed for extreme competition.
