Eagle Chevy LS1 4.000in Crank 24 Tth Reluctor 6.125in I-Beam Rods 3.913in Pistons Rotating Assembly

This Eagle Pro Street Rotating Assembly gives you the core components to build a strong foundation for your Chevy LS1 engine, specifically suited for naturally-aspirated racing applications. You get a 4.000-inch forged 4140 crankshaft, a 24-tooth reluctor wheel, 6.125-inch long 4340 I-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and 3.913-inch forged 4032 DSS flat-top pistons with a -5cc dish. This assembly also includes plasma-moly file-fit piston rings and King XP rod and main bearings to get you started.

The forged 4140 crankshaft is built to handle the stresses of racing, while the 4340 I-beam connecting rods offer a solid balance of strength and weight for performance builds. The 4032 forged pistons are a popular choice for their thermal expansion properties, helping to maintain good piston-to-wall clearance as the engine heats up. The included ARP bolts are well-known for their reliability in high-stress applications. This assembly is designed for naturally-aspirated use, meaning it's optimized for engines that don't use forced induction like turbochargers or superchargers.

When building a performance engine, especially for racing, the rotating assembly is critical. This Eagle kit provides a well-matched set of components from a popular manufacturer in the performance aftermarket. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and balancing procedures.
