Eagle Chevy 502 4.250in Counterweight Crank 6.535in H-Beam 40cc 4.530in Pistons Rotating Assembly

If you're building a serious performance Chevy 502 engine for extreme competition, this Eagle rotating assembly is a solid foundation. It's designed to handle the intense demands of exotic fuels, heavy nitrous use, and high boost applications. This is a complete package that brings together the critical components needed to build a powerful and reliable engine.

At the heart of this assembly is a 4.250-inch forged 4340 steel crankshaft, featuring a center counterweighted design for improved balance and reduced stress on the engine. Paired with this are 6.535-inch H-beam connecting rods, known for their strength and durability under high loads. These rods are secured with 7/16-inch ARP L19 bolts, a strong choice for high-performance builds. The pistons are forged 2618 JE units with a 40cc dome and a 4.530-inch bore size, designed to work with the crank and rods for optimal combustion chamber volume. This assembly also includes plasma-moly file-fit piston rings, allowing for precise gap setting to match your specific engine build, and King XP rod and main bearings, which offer excellent wear resistance and performance in demanding conditions.

This rotating assembly is a significant investment in your engine's performance and longevity. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure you get the most out of this heavy-duty component.
