Eagle Chevy 496 1pc Rear Main Seal Balanced Rotating Assembly

Eagle has a solid reputation for building robust engine components, and this balanced rotating assembly is a prime example of their work for street performance. If you're building a Chevy 454 with a focus on pump gas and naturally aspirated power, this assembly is designed to handle that kind of application.

This assembly includes a 4.250-inch cast crankshaft and 6.385-inch I-beam connecting rods, which are secured with 7/16-inch ARP 8740 bolts. Forged 4032 Mahle pistons with an 18cc dome and a 4.310-inch bore size are included, along with plasma-moly file-fit rings, meaning you can gap them precisely for your build. You'll also get King rod and main bearings, a Pioneer damper, and a 168-tooth flexplate to complete the package.

This is a balanced rotating assembly, which is a critical step for ensuring smooth operation and longevity in a performance engine. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and setup.
