Eagle Chevy 454 4.000in Crank 6.135in H-Beam 18cc Closed Chamber 4.350in Pistons Rotating Assembly

Starting with a 4.000-inch forged 4340 crankshaft, this Eagle rotating assembly is built for serious performance, especially in racing applications that might involve nitrous or forced induction. The crankshaft is paired with 6.135-inch H-beam connecting rods, which are known for their strength and ability to handle high loads. These rods come equipped with 7/16-inch ARP 8740 bolts, a strong choice for ensuring reliable connections under stress.

The pistons are forged 2618 material from ICON, featuring a 4.350-inch bore size and an 18cc closed chamber dome design. This dome shape is specific and contributes to the compression ratio and combustion characteristics of the engine. The assembly includes plasma-moly file-fit rings, which allow for precise gapping to match your specific engine build and ensure good sealing. For the bearings, Eagle has included King XP rod and main bearings, which are designed for high-performance lubrication and wear resistance.

This is a complete rotating assembly designed to be a robust foundation for a high-output Chevy 454 engine. 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.
