Eagle Chevy LS3 4.125in Crank 58 Tth Reluctor 6.125in H-Beam -8cc 4.070in Pistons Rotating Assembly

If you're building a serious performance LS3 engine, especially one intended for racing, nitrous, or forced induction, a strong rotating assembly is the heart of the operation. This Eagle competition rotating assembly is built to handle the demands of high-horsepower applications. It starts with a robust 4.125-inch forged 4340 crankshaft, designed for durability under extreme stress. Paired with this are 6.125-inch H-beam connecting rods, secured with 7/16-inch ARP 8740 bolts, which are well-known for their strength and reliability in performance builds.

The pistons in this assembly are forged 4032 Mahle flat tops, featuring a -8cc dish to help achieve your desired compression ratio, and they are sized at 4.070 inches. They come complete with plasma-moly file-fit rings, giving you the flexibility to set your ring gaps precisely for your specific application, which is crucial for sealing and performance in boosted or nitrous engines. For the bottom end, King XP rod and main bearings are included, offering excellent wear resistance and smooth operation under load. This assembly is specifically configured for a 58-tooth reluctor wheel, common in many LS applications.

This is a comprehensive package for anyone looking to build a powerful and reliable LS3 engine. Keep in mind 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 break-in procedures to ensure the longevity of your new engine.
