Eagle Chevrolet/Pontiac LS-Series Competition Assembly 4.030in Bore 6.125in H-Beam

Eagle has a solid reputation for building tough engine components, and this Competition Rotating Assembly is a prime example of that. If you're building a high-performance LS-series engine for serious racing, especially with nitrous or forced induction, this assembly is designed to handle the stress. It's a complete package that gives you a strong foundation for your build, fitting a wide range of popular GM vehicles like the Chevrolet Corvette, Camaro, and Pontiac Firebird.

At the heart of this assembly is a 4.000-inch forged 4340 steel crankshaft, known for its strength and durability under high loads. Paired with it are 6.125-inch H-beam connecting rods, which are also forged from 4340 steel and come with 7/16-inch ARP 8740 bolts for a secure connection. The pistons are forged 4032 aluminum from Mahle, featuring an inverted dome design with a -26cc volume and a 4.030-inch bore, perfect for achieving specific compression ratios. They come with plasma-moly file-fit rings, giving you the flexibility to set your ring gap precisely for your application. To top it off, this assembly includes King XP rod and main bearings, offering excellent wear resistance and smooth operation.

This is a comprehensive rotating assembly intended for demanding applications. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions to ensure proper assembly and setup for your specific engine build.
