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

When you're building a serious performance engine, especially for racing, you need a rotating assembly that can handle the stress. This balanced assembly from Eagle is built for just that, designed to be a strong foundation for your Chevy 454 build. It comes complete with a forged 4.000-inch crankshaft, ready to take on high-RPM use and significant power adders like nitrous or forced induction.

You'll find 6.135-inch H-beam connecting rods included, which are known for their strength and reliability under load. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their durability and consistent clamping force. The pistons are forged 2618 Icon units, featuring a 43cc dome and a 4.280-inch bore size, designed to work with the included plasma-moly file-fit ring set. To ensure proper bearing performance and longevity, the assembly also includes King XP rod and main bearings.

This is a fully balanced assembly, meaning the critical rotating components have been precisely weighted and matched at the factory. This reduces engine vibration and lessens the load on your main bearings, contributing to a smoother running engine and potentially longer component life. This assembly is intended for competition use and is not CARB approved, so it cannot be shipped to California.
