About this part

Product Details

If you're building a high-performance LS engine for serious racing, especially with nitrous or forced induction, a strong rotating assembly is the heart of your build. This Eagle Competition Rotating Assembly is designed to handle the extreme demands of these applications. It includes a forged crankshaft, robust connecting rods, and durable pistons, all balanced and ready to be installed in your Chevy LS 4.8L or 5.3L engine.

At its core is a 4.000-inch forged 4340 steel crankshaft, chosen for its strength and ability to withstand high cylinder pressures. The assembly features 6.125-inch H-beam connecting rods, known for their excellent strength-to-weight ratio, secured with 7/16-inch ARP 8740 bolts. These rods connect to forged 4032 DSS pistons with a -5cc flat top dish and a 3.780-inch bore, designed for optimal combustion chamber volume and performance. The pistons come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's specific needs and boost levels. King XP rod and main bearings are included, offering improved lubrication and wear resistance under heavy loads.

This assembly is specifically configured for a 58-tooth reluctor wheel, common in many LS applications. While built for competition, please note that this part is not CARB approved and cannot be shipped to California. It's a well-built foundation for a powerful LS engine build.
