About this part

Product Details

This Eagle Pro Street rotating assembly starts with a 4.000-inch forged 4140 crankshaft, a solid foundation for building a powerful LS3 engine. It's designed for naturally-aspirated racing applications, meaning it's optimized for engines that don't use forced induction like turbos or superchargers. The crankshaft features a 58-tooth reluctor wheel, which is standard for many LS engines, ensuring compatibility with your engine management system.

Complementing the crankshaft are 6.125-inch I-beam connecting rods made from strong 4340 steel. These rods are secured with 7/16-inch ARP 8740 bolts, known for their reliability under stress. The assembly includes forged 4032 DSS pistons with an inverted dome design, featuring a -29cc dish to help achieve your desired compression ratio. These pistons come with plasma-moly file-fit rings, which allow for precise gap setting during installation for optimal sealing and performance. King XP rod and main bearings are also included, offering well-built protection for your rotating assembly.

This is a comprehensive package for anyone looking to rebuild or significantly upgrade their Chevy LS3 engine for racing. It's important to note 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.
