About this part

Product Details

This Eagle rotating assembly gives you the core components for a serious Chevy LS1 engine build. Inside this kit, you'll find a 4.000-inch forged 4340 crankshaft, a 58-tooth reluctor wheel, 6.125-inch H-beam connecting rods with 7/16-inch ARP 2000 bolts, and heavy-duty flat-top pistons from JE. The pistons are -5cc dish and measure 3.905 inches in bore size, and they come with plasma-moly file-fit rings. You also get King XP rod and main bearings to complete the assembly.

This is a well-built setup designed for the most demanding applications. Whether you're running exotic fuels, heavy nitrous, or high boost, the forged 4340 crank and 6.125-inch H-beam rods are made to handle extreme stress. The JE pistons are forged from 2618 aluminum, a strong material often used in high-performance applications, and the plasma-moly rings are designed for durability and proper sealing. The inclusion of ARP 2000 bolts for the connecting rods means you're getting strong, reliable fasteners right out of the box.

When building a high-performance LS1, getting the rotating assembly right is crucial for reliability and power. This Eagle kit provides a solid foundation with quality components. Remember that this assembly is not CARB approved and cannot be shipped to California. You'll want to ensure you have all the necessary machine work done and follow proper assembly procedures for your specific build.
