About this part

Product Details

What you get in this Eagle rotating assembly is a complete package designed to handle serious power for your Chevy LS3 engine. This kit includes a 4.000-inch forged 4340 steel crankshaft, which is a strong foundation for any high-performance build. You also get 6.125-inch H-beam connecting rods, known for their robust design, secured with 7/16-inch ARP 8740 bolts. The pistons are forged 4032 DSS units with an inverted dome, measuring 4.065 inches in bore size and featuring a -15cc dish to help achieve your desired compression ratio. This assembly also comes with plasma-moly file-fit piston rings and King XP rod and main bearings, ensuring smooth operation and durability.

This is a competition-level assembly, meaning it’s built for the demands of racing, including setups that use nitrous or forced induction. The 4340 forged steel crankshaft and the H-beam rods are chosen for their strength under high stress. The 58-tooth reluctor wheel is specific to certain LS3 applications, so make sure it matches your ECU requirements. The included King XP bearings are a well-regarded choice for performance applications, offering good wear resistance and low friction.

When putting this assembly into your LS3, remember that the piston rings are file-fit, meaning they need to be gapped to your specific cylinder wall clearance before installation. This is a standard procedure for performance engines to ensure proper sealing and longevity. This rotating assembly is a significant upgrade for anyone looking to build a powerful LS3 engine for track use or demanding street performance.
