About this part

Product Details

Eagle has a solid reputation for making well-built performance engine components, and this balanced rotating assembly is a prime example for your Chevy LS2 build. If you're putting together a naturally-aspirated racing engine, this assembly is designed to handle the demands of that kind of use. It's a complete package that gives you the core rotating parts you need to get your engine built.

This assembly starts with a 4.000-inch forged 4140 crankshaft, which is a strong foundation for any performance engine. It's paired with 6.125-inch 4340 I-beam connecting rods, known for their strength and reliability in performance applications. These rods use 7/16-inch ARP 8740 bolts, a popular choice for their durability and ability to hold up under stress. The pistons are forged 4032 DSS with an inverted dome design, sized at 4.030 inches, and come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's needs. To top it off, it includes King XP rod and main bearings, which offer excellent performance and wear resistance. The entire assembly is balanced, meaning it's ready to be installed with less balancing work required at the machine shop, saving you time and money.

This assembly is specifically configured for a 58-tooth reluctor wheel, common in many LS engine applications. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
