About this part

Product Details

This is the Eagle Chevy LS2 rotating assembly, a complete package designed to form the heart of your high-performance engine build. Inside this kit, you'll find a 4.000-inch forged 4340 crankshaft, a 24-tooth reluctor wheel for crank trigger signals, and a set of 6.125-inch H-beam connecting rods. It also includes forged 2618 CP pistons with an inverted dome design, measuring 4.005 inches in bore size and featuring a -27.5cc volume. To complete the assembly, you get plasma-moly file-fit piston rings and King XP rod and main bearings.

This assembly is built for serious use, perfect for all forms of racing, including applications using nitrous oxide or forced induction. The forged 4340 steel crankshaft and 6.125-inch H-beam connecting rods are strong enough to handle the stresses of high RPM and significant power output. The CP pistons are forged from 2618 aluminum, a material known for its strength and ability to withstand high temperatures and pressures, making them ideal for boosted or nitrous applications. The included ARP 8740 bolts for the connecting rods are a well-known standard for strength and reliability in performance engine builds. The file-fit plasma-moly rings allow for precise gap setting to optimize performance and sealing in your specific application, while the King XP bearings are designed for demanding conditions.

This rotating assembly is intended for use with a Chevy LS2 engine platform. Please note that this part is not CARB approved and cannot be shipped to California. It's crucial to consult your engine builder or refer to the manufacturer's detailed installation instructions for proper assembly and tuning, especially when dealing with file-fit rings and specific piston-to-wall clearances.
