About this part

Product Details

This is the Eagle Chevy LS7 4.000-inch crankshaft, 58-tooth reluctor, 6.125-inch H-beam connecting rod, and 4.155-inch piston rotating assembly. It's a complete package designed for high-performance LS7 engines, especially those built for racing applications. If you're assembling a serious performance engine, this rotating assembly is a solid foundation that brings together critical components from a well-known name in performance parts.

At the heart of this assembly is a 4.000-inch forged 4340 steel crankshaft, chosen for its strength and durability under demanding conditions. Paired with it are 6.125-inch H-beam connecting rods, also forged from 4340 steel, and secured with 7/16-inch ARP 8740 bolts. These rods are built to handle the significant forces generated in racing engines, including those using nitrous or forced induction. The pistons are forged 2618 aluminum with a -4.6cc flat top dish, designed for a 4.155-inch bore, and come with plasma-moly file-fit rings. This setup is completed with King XP rod and main bearings, known for their robust performance and reliability in high-stress environments. The 58-tooth reluctor wheel is included for compatibility with specific LS engine management systems.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a comprehensive kit that simplifies the process of building a powerful LS7 engine, ensuring that key rotating components are matched for performance and strength right out of the box.
