About this part

Product Details

Eagle is well-known for building strong rotating assemblies that can handle serious power, and this Competition Rotating Assembly is a prime example for your Chevy LS7 engine. If you're building a high-performance LS7 for racing, especially with nitrous or forced induction, this assembly is designed to take the abuse. It’s a complete package that gives you the core components needed to build a robust bottom end.

This assembly starts with a 4.000-inch forged 4340 steel crankshaft featuring a long snout, which is important for certain accessory drives. It’s set up for a 58-tooth reluctor wheel, common on many LS engines. The connecting rods are 6.125-inch long H-beams, known for their strength, and they come with 7/16-inch ARP 8740 bolts for a secure connection. For the pistons, you get forged 2618 CP pistons that are flat-top with a -4.6cc dish, designed for a 4.135-inch bore. They come with plasma-moly file-fit rings, meaning you can gap them precisely for your application. To finish it off, King XP rod and main bearings are included, offering excellent performance and durability for demanding use.

This is a comprehensive rotating assembly for serious LS7 builds. Please note that this assembly is not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or a trusted mechanic to ensure all components are compatible with your specific build goals and supporting modifications.
