Eagle Chevrolet/Pontiac LS-Series Competition Assembly 4.030in Bore 6.125in H-Beam

Starting with a forged 4340 steel crankshaft and 4.030-inch forged 4032 Mahle pistons featuring a -4cc flat top design, this Eagle Competition Rotating Assembly is built for serious performance. It includes 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, plasma-moly file-fit rings, and King XP rod and main bearings. This assembly is designed for Chevrolet and Pontiac LS-series engines and is well-suited for all forms of racing, including applications using nitrous or forced induction.

This is a comprehensive rotating assembly that forms the heart of a high-performance engine build. The 4340 forged crank offers improved strength over cast or hypereutectic components, essential for handling the increased stresses of racing. The Mahle pistons are forged for durability and feature a specific dome volume to achieve a desired compression ratio when paired with appropriate cylinder heads. The H-beam rods are a popular choice for their robust design, and the inclusion of ARP bolts means you have strong, reliable fasteners for the connecting rods.

This assembly is designed to fit a range of popular LS-powered vehicles, including models like the Chevrolet Camaro, Corvette, and Pontiac Firebird. It's important to note that this assembly is not CARB approved and cannot be shipped to California. For a complete engine build, consider pairing this rotating assembly with appropriate camshafts, cylinder heads, and a quality engine block to maximize its potential.
