Eagle Chevy 454 1Pc 4.250in Counterwght Crank 6.385in H-Beam 43cc 4.280in Pistons Rotating Assembly

Eagle is a well-known name for building strong engine components, and this rotating assembly is a prime example of their commitment to durability. If you're building a high-performance Chevy 454 for serious competition, this assembly is designed to handle the most demanding conditions, including exotic fuels, heavy nitrous use, and high boost applications.

At the heart of this assembly is a 4.250-inch forged 4340 steel crankshaft featuring center counterweighting. This design helps to balance the rotating mass more effectively, reducing stress on your engine's bearings and improving overall smoothness. Paired with the crank are 6.385-inch H-beam connecting rods, which are known for their strength and reliability under high loads. These rods come equipped with 7/16-inch ARP L19 bolts, a serious upgrade that ensures a secure connection even under extreme cylinder pressures.

The pistons are forged 2618 aluminum from Mahle, featuring a 43cc dome and a 4.280-inch bore size. These are designed to work with the included plasma-moly file-fit piston rings, allowing you to achieve precise ring-to-wall clearance for optimal sealing and performance. To complete the package, the assembly includes King XP rod and main bearings, offering excellent wear resistance and smooth operation. This is a comprehensive, well-built rotating assembly ready for your most ambitious engine build.
