About this part

Product Details

This is the Eagle Competition Rotating Assembly for Chevy LS2 engines, designed for serious performance applications like racing, including those using nitrous or forced induction. What you get in this kit is a complete package to rebuild the core of your engine's power generation. It includes a 4.000-inch forged 4340 steel crankshaft with a long snout for specific accessory drive setups, a 58-tooth reluctor wheel for crank position sensing, 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and 4.010-inch SRP forged 4032 pistons featuring an inverted dome design with a -10cc volume. The assembly also comes with plasma-moly file-fit piston rings and King XP series rod and main bearings for a well-matched rotating assembly.

The choice of materials here is key for durability under high stress. The 4340 forged steel crankshaft and H-beam connecting rods are well-built to handle the increased cylinder pressures and rotational forces common in racing. The SRP pistons are forged from 4032 aluminum, which offers a good balance of strength and thermal expansion characteristics suitable for demanding builds. The inclusion of ARP bolts for the connecting rods means you're getting strong, reliable fasteners. The plasma-moly rings are designed for good sealing and durability, and the King XP bearings are chosen for their performance in high-load situations. This assembly is intended for builders who need a robust foundation for a high-horsepower LS2 engine.

When planning your build, remember that this assembly is not CARB approved and cannot be shipped to California. It's crucial to ensure all components are properly balanced and clear the cylinder walls and block before final assembly. This kit provides the core rotating components, so you'll still need to source other necessary engine parts like gaskets, seals, oil pump, and timing set to complete your engine.
