This Eagle Pro Street rotating assembly starts with a forged 4.000-inch crankshaft made from 4140 steel, a solid foundation for a high-performance LS engine build. It's designed for naturally-aspirated racing applications, meaning it's built to handle the demands of the track without forced induction. The assembly includes a 58-tooth reluctor wheel, essential for proper engine management on many LS applications.

You'll find 6.125-inch I-beam connecting rods forged from 4340 steel, paired with 7/16-inch ARP 8740 bolts for strong, reliable connections. The pistons are forged 4032 DSS with an inverted dome design, measuring 3.800 inches in diameter, and come with plasma-moly file-fit rings. This setup is balanced as an assembly, saving you a crucial step in the engine building process. King XP rod and main bearings are also included, offering robust lubrication and wear resistance.

This balanced assembly is a significant step towards building a powerful naturally-aspirated LS engine. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
