Product Details

If you're building a high-performance Chevy LS2 engine for serious racing, especially with nitrous or forced induction, a robust rotating assembly is key. This Eagle Competition Rotating Assembly is designed to handle the extreme demands of competition, providing a solid foundation for your build. It includes a forged 4340 steel crankshaft, I-beam connecting rods, and custom pistons, all balanced and ready to go.

Paired with it are 6.125-inch I-beam connecting rods, which are strong and well-suited for high-RPM use. These rods come with 7/16-inch ARP 8740 bolts, known for their reliability under stress. The pistons are forged 4032 aluminum from Mahle, featuring an inverted dome design with a -28cc dish and a 4.030-inch bore size, complete with plasma-moly file-fit rings for improved sealing and reduced friction.
