Eagle Chevy LS1 4.000in Crank 58 Tth Reluctor 6.125in H-Beam -20cc 3.905in Pistons Rotating Assembly

This Eagle Heavy Duty Rotating Assembly is a complete package designed for serious performance builds, especially those pushing the limits with exotic fuels, heavy nitrous use, or high boost applications. You get a forged 4.000-inch crankshaft, 6.125-inch H-beam connecting rods with 7/16-inch ARP 2000 bolts, and custom JE pistons. The pistons are forged from 2618 aluminum, feature an inverted dome design with a -20cc volume for forced induction, and come with plasma-moly file-fit rings. This assembly also includes King XP rod and main bearings to ensure smooth operation under extreme stress.

The forged 4340 steel crankshaft is built to handle significant power, and the 58-tooth reluctor wheel is specific for LS1 engine management systems. The 6.125-inch H-beam rods are a popular choice for their strength and weight, especially when paired with the included ARP 2000 bolts, which offer improved clamping force over standard rod bolts. The JE pistons are designed for forced induction, meaning they are built to withstand the increased cylinder pressures associated with turbocharging or supercharging, and the file-fit rings allow for precise gap setting to optimize performance and sealing in high-stress environments.

This rotating assembly is a well-built foundation for a high-performance LS1 engine. It includes everything you need to get started on rebuilding or upgrading your engine's core rotating components. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and tuning procedures.
