Eagle Chevy 454 4.000in Crank 6.135in H-Beam 38cc Dome 4.250in Pistons Balanced Assembly

Starting with a forged 4340 steel crankshaft featuring a 4.000-inch stroke, 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, known for their strength and reliability under high stress. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their durability and consistent clamping force, ensuring the rods stay firmly attached even under extreme loads.

The assembly includes forged 2618 aluminum pistons from ICON, specifically designed with a 38cc dome to achieve a desired compression ratio with the 454 cubic inch engine. These pistons are paired with plasma-moly file-fit rings, allowing for precise gap setting to optimize sealing and performance. For smooth operation and robust bearing support, the assembly comes complete with King XP series rod and main bearings, which offer improved wear resistance and oil clearance for longevity.

This balanced assembly is ready to be installed into your Chevy 454 engine. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
