Eagle Chevy 502 Tall 4.750in Counterweight Crank 6.700in H-Beam 4.625in Pistons Balanced Assembly

When you're building a serious performance engine, especially for a Chevy 502 application, what you get inside this box is a complete, balanced rotating assembly. This includes a forged 4340 steel crankshaft with a 4.750-inch stroke and center counterweights, designed for heavy-duty use. You also get 6.700-inch long H-beam connecting rods, which are known for their strength and are secured with 7/16-inch ARP L19 bolts. Rounding out the assembly are forged 2618 JE pistons, measuring 4.625 inches in bore size with a -3cc flat top design, and plasma-moly file-fit piston rings. King XP rod and main bearings are also included to ensure smooth operation and durability.

This assembly is built for the most demanding situations, including exotic fuels, heavy nitrous use, and high boost applications. The forged 4340 steel crank and H-beam rods are well-built to handle significant stress, while the JE pistons are forged for strength and lighter weight. The ARP L19 bolts are a strong choice for high-stress connections. Having the assembly balanced from the factory saves you a significant step and ensures proper rotating balance, which is critical for engine longevity and performance at high RPMs.

This rotating assembly is a solid option for anyone rebuilding or building a high-performance Chevy 502 engine. Keep in mind that this part is not CARB approved and cannot be shipped to California. For installation, it's always recommended to consult the manufacturer's detailed instructions and ensure all related components, such as the block, cylinder heads, and camshaft, are compatible and properly prepared for a high-performance build.
