Product Details
This Eagle rotating assembly is a complete package for your Chevy LS2 engine build, designed to handle the rigors of racing. You get a forged 4.000-inch stroke crankshaft made from 4340 steel, a 24-tooth reluctor wheel for crank trigger systems, and 6.125-inch H-beam connecting rods. The rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability in high-stress applications. This assembly also includes forged 4032 DSS pistons with a -5cc flat top design, measuring 4.040 inches in bore size, and plasma-moly file-fit piston rings. To complete the package, King XP rod and main bearings are included, offering robust performance for your engine's critical rotating components.
Eagle has put together this competition assembly with racing in mind, making it suitable for applications using nitrous or forced induction. The use of forged 4340 steel for the crankshaft and H-beam connecting rods means these parts are well-built to withstand higher cylinder pressures and RPMs than stock components. The 4032 aluminum alloy for the pistons offers good thermal expansion characteristics, which is beneficial in high-performance engines, and the flat-top design with a -5cc dish is ideal for achieving specific compression ratios when paired with appropriate cylinder heads. The plasma-moly file-fit rings allow for precise gapping to match your engine's bore and intended use, ensuring optimal sealing and performance.
This assembly is a solid foundation for a powerful LS2 engine build. Keep in mind that this specific rotating assembly is not CARB approved and cannot be shipped to California. For installation, it's always recommended to consult the manufacturer's detailed instructions and ensure all clearances and tolerances are checked before final assembly to achieve the best results for your engine.
