Eagle Chevy 454 4.000in Crank 6.135in H-Beam 43cc Dome 4.280in Pistons Balanced Assembly

Starting with a 4.000-inch forged 4340 crankshaft, this balanced rotating assembly from Eagle is built for serious performance, especially in racing applications that might use nitrous or forced induction. The crankshaft is paired with 6.135-inch H-beam connecting rods, which are known for their strength and reliability under high stress. These rods come equipped with 7/16-inch ARP 8740 bolts, a solid choice for ensuring a secure connection under extreme loads.

The pistons are forged 2618 aluminum from ICON, featuring a 43cc dome and a 4.280-inch bore size, designed to work with the specific compression ratio and cylinder head volume you're aiming for. This assembly includes plasma-moly file-fit piston rings, allowing for precise gap setting to match your engine's bore and intended use, which is crucial for optimal sealing and performance. To complete the package, King XP rod and main bearings are included, offering robust lubrication and wear resistance for the critical rotating components.

This balanced assembly means the crankshaft, rods, pistons, and rings have been precisely weighted and balanced together at the factory. This reduces internal engine vibration and stress on your main bearings and crankshaft, contributing to a smoother running engine and potentially longer component life. It's important to note that this assembly 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.
