Eagle Chevy 502 Tall 4.625in Counterwght Crank 6.800in H-Beam 49cc 4.610in Pistons Balanced Assembly

What you get in this balanced rotating assembly is a complete package built for serious performance. It includes a 4.625-inch forged 4340 crankshaft with center counterweights, 6.800-inch H-beam connecting rods fitted with 7/16-inch ARP L19 bolts, 4.610-inch JE pistons with a 49cc dome volume, plasma-moly file-fit piston rings, and King XP rod and main bearings.

This assembly is designed for the most demanding engine builds, whether you're running exotic fuels, heavy nitrous, or high boost applications. The forged 4340 steel crankshaft is a strong foundation, and the center counterweight design helps manage rotational forces. Paired with the robust H-beam connecting rods and ARP L19 bolts, this setup is built to handle significant stress. The JE pistons are forged from 2618 aluminum for strength and feature a specific dome volume to achieve your desired compression ratio, while the plasma-moly rings are designed for good sealing and durability. King XP bearings are included to ensure smooth operation and longevity for both the crankshaft and connecting rods.

This is a balanced assembly, meaning the crankshaft, connecting rods, pistons, rings, and bearings have been precisely balanced together at the factory to reduce vibration and improve overall engine smoothness and reliability. This level of attention to detail is crucial for high-performance engines where balance is key to preventing premature wear and maximizing power output. Keep in mind this assembly is not CARB approved and cannot be shipped to California.
