Eagle Chevy 454 4.250in Crank 6.385in I-Beam Rods -3cc Flat Top 4.280in Pistons Balanced Assembly

Eagle has a solid reputation for making well-built performance engine components, and this balanced rotating assembly is a prime example for your Chevy 454. If you're building a naturally-aspirated racing engine or a serious street performance build, this assembly is designed to handle the demands. It includes everything you need to get your short block started, all balanced and ready to go.

This assembly starts with a forged 4140 steel crankshaft featuring a 4.250-inch stroke, giving you that extra displacement for more power. Paired with it are 6.385-inch I-beam connecting rods made from strong 4340 steel, secured with 7/16-inch ARP 8740 bolts for reliable clamping force. The pistons are forged 4032 aluminum from Mahle, designed with a -3cc flat top dish to work with your cylinder head volume and a 4.280-inch bore size. They come with plasma-moly file-fit rings, which means you can gap them precisely to your engine's needs for optimal sealing and performance. To top it off, King XP series rod and main bearings are included, known for their durability and performance under load.

This is a balanced rotating assembly, meaning the crankshaft, connecting rods, pistons, rings, and bearings have been precisely weighted and balanced together at the factory. This reduces engine vibration and stress on your main bearings, crucial for high-RPM operation and overall engine longevity. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
