Product Details
If you're building a high-performance Chevy LS3 engine for serious street or track use, a strong rotating assembly is the heart of your build. This Eagle Competition Rotating Assembly is designed to handle the demands of boosted or nitrous-fed applications, providing a solid foundation for significant power gains. It includes a forged crankshaft, robust connecting rods, and custom pistons, all balanced and ready to be installed.
At its core is a 3.622-inch forged 4340 steel crankshaft, chosen for its strength and durability under high stress. Paired with this are 6.125-inch H-beam connecting rods, known for their excellent strength-to-weight ratio, secured with 7/16-inch ARP 8740 bolts. The assembly comes with 4.030-inch Mahle forged 4032 pistons featuring a -4cc flat top design and plasma-moly file-fit rings, which are crucial for proper sealing and performance in high-compression or forced-induction scenarios. King XP rod and main bearings are also included, offering improved lubrication and wear resistance.
This assembly is specifically configured for an LS3 engine with a 58-tooth reluctor wheel, ensuring compatibility with common LS engine management systems. While this kit is built for extreme performance, please note it is not CARB approved and cannot be shipped to California. It's a well-built package for anyone looking to push their LS3 engine to its limits.
