Eagle Chevy LS1 4.000in Crank 24 Tth Reluctor 6.125in H-Beam -5cc 3.905in Pistons Rot Assembly

If you're building a serious performance LS1 engine for extreme competition, this Eagle rotating assembly is a solid foundation. It's designed to handle the demands of exotic fuels, heavy nitrous use, and high boost applications, giving you the confidence to push your engine hard. This assembly includes a forged 4.000-inch crankshaft, 6.125-inch H-beam connecting rods with ARP 2000 bolts, and custom-forged JE pistons with a -5cc dish for a 3.905-inch bore. It also comes with plasma-moly file-fit rings and King XP rod and main bearings, ensuring everything is ready for a robust build.

Eagle has put together a well-built package here, starting with a forged 4340 steel crankshaft for strength and durability. The 6.125-inch H-beam rods are a popular choice for their balance of strength and weight, and they're paired with 7/16-inch ARP 2000 bolts, known for their reliability under high stress. The JE pistons are forged from 2618 aluminum, a material chosen for its ability to withstand high temperatures and pressures, and they feature a -5cc dish to help achieve your desired compression ratio. The included plasma-moly file-fit rings allow for precise gap setting, which is crucial for optimal sealing and performance in a high-output engine. King XP bearings are also included, offering excellent wear resistance and performance.

This assembly is specifically configured for a 24-tooth reluctor wheel, common in many LS1 applications. It's important to note that this part is not CARB approved and cannot be shipped to California. When planning your build, ensure you have all the necessary supporting components, such as a balanced flexplate or flywheel, and consider professional balancing if your specific application requires it, though this assembly is designed for excellent balance out of the box.
