Product Details
This Eagle Competition Rotating Assembly gives you the core components to rebuild or upgrade your Chevy LS3 engine. You get a 4.000-inch forged 4340 crankshaft, a 58-tooth reluctor wheel for crank trigger systems, and a set of 6.125-inch H-beam connecting rods. It also includes 7/16-inch ARP 8740 bolts to secure those rods. The assembly is topped off with 4.075-inch forged 2618 Mahle pistons featuring an inverted dome design with a -14cc volume, and plasma-moly file-fit piston rings. To finish it off, King XP rod and main bearings are included, ready to be installed.
This is a well-built assembly designed for demanding use, including racing applications that might involve nitrous or forced induction. The forged 4340 steel crankshaft is strong and durable, ready to handle significant power. The H-beam connecting rods are also forged and come with ARP bolts, known for their reliability under stress. The Mahle pistons are forged from 2618 aluminum, a material chosen for its strength and ability to withstand high temperatures and pressures, and the -14cc dome helps manage compression ratios for boosted or nitrous setups. The plasma-moly file-fit rings allow for precise gapping to match your specific engine build and power adder.
This rotating assembly is a solid foundation for a high-performance LS3 build. It's important to note 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 torque specifications, especially when dealing with critical components like connecting rod bolts and main bearing caps.
