Eagle Chevy 454 Balanced Forged Pro Street Rotating Assembly Kit

This is the Eagle Chevy 454 Balanced Forged Pro Street Rotating Assembly Kit, designed for serious performance builds. If you're putting together a naturally-aspirated racing engine based on the Chevy 454 big block, this kit gives you the core components to build a strong foundation.

Inside this balanced assembly, you'll find a forged 4140 crankshaft with a 4.250-inch stroke. Paired with that are 6.385-inch 4340 forged I-beam connecting rods, secured with 7/16-inch ARP 8740 bolts. For the pistons, Eagle includes forged 2618 Mahle units with a 43cc dome and a 4.310-inch bore size, ready for a high-compression setup. The kit also comes with plasma-moly file-fit piston rings and King XP rod and main bearings, ensuring smooth operation and durability under demanding conditions. Having the rotating assembly balanced from the factory saves you a significant step and ensures proper weight distribution for optimal engine performance and longevity.

This kit is intended for racing applications and is not CARB approved, meaning it cannot be shipped to California. Ensure you have the necessary machine work and assembly knowledge, or consult a professional engine builder, to properly install these critical components.
