This Eagle rotating assembly gives you the core components to rebuild or upgrade your Chevy LS 4.8L or 5.3L engine. You get a 4.000-inch stroke forged crankshaft with a 24-tooth reluctor wheel, a set of 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and 3.780-inch forged 4032 DSS pistons featuring an inverted dome design with a -15cc volume. This assembly also includes plasma-moly file-fit piston rings and King XP rod and main bearings, so you have a solid foundation for your engine build.

Eagle designed this rotating assembly for serious performance applications, including racing use with nitrous or forced induction. The forged 4340 steel crankshaft is built to handle significant stress, and the H-beam connecting rods with ARP bolts offer a strong link between the crank and pistons. The 4032 forged aluminum pistons are well-suited for high-horsepower builds, and the included file-fit rings allow for precise gap setting to optimize performance and sealing. King XP bearings are known for their durability and ability to maintain oil film under demanding conditions.

This is a comprehensive package for anyone looking to build a high-performance LS engine. Remember 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 torque specifications.
