Product Details
This is the Eagle Chevy LS3 Pro Street rotating assembly, built for naturally-aspirated racing applications. It includes a 4.000-inch forged 4140 crankshaft with a 24-tooth reluctor, 6.125-inch 4340 I-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and 4.070-inch forged 4032 DSS flat-top pistons with a -5cc dish. This assembly is designed to be a solid foundation for a high-performance LS3 engine build.
The forged 4140 crankshaft offers a strong core for handling the stresses of racing, while the 4340 I-beam rods are well-built for their intended use. The included pistons are forged 4032 aluminum, which is a good choice for performance applications due to its strength and thermal expansion properties, and they come with plasma-moly file-fit rings. King XP rod and main bearings are also part of this package, offering reliable lubrication and wear protection for the rotating assembly.
This rotating assembly is a popular choice for builders looking to put together a potent LS3 engine for track use or street performance where natural aspiration is the goal. Please note that this assembly is not CARB approved and cannot be shipped to California. It's important to consult with your engine builder or refer to manufacturer instructions for proper installation and balancing procedures.
