Product Details
This Eagle Competition Rotating Assembly is a complete package for your Chevy LS3 engine build, designed to handle the rigors of racing. Inside this assembly, you'll find a 4.000-inch forged 4340 crankshaft, ready for a 24-tooth reluctor wheel setup. It also includes 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability under high stress. The assembly is topped off with Mahle forged 2618 pistons, featuring an inverted dome design with a -14cc volume and a 4.075-inch bore size, along with plasma-moly file-fit rings to ensure a good seal.
Eagle has put together this assembly with performance and durability in mind, making it a solid choice for builds aiming for significant power, especially those considering nitrous or forced induction. The use of forged 4340 steel for the crankshaft and forged 2618 aluminum for the pistons means these components are well-built to withstand higher cylinder pressures and temperatures common in racing applications. The inclusion of King XP rod and main bearings further supports the robust nature of this assembly, providing reliable lubrication and wear resistance for the rotating components.
This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. When planning your build, remember that this is a core component, and you'll need to source other necessary engine parts like cylinder heads, camshaft, and block preparation to complete your LS3 engine.
