Eagle Chevy LS1 4.000in Crank 24 Tth Reluctor 6.125in H-Beam -15cc 3.900in Pistons Rotating Assembly

Starting with a 4.000-inch forged 4340 steel crankshaft, this Eagle rotating assembly is built for serious performance, especially in racing applications that might use nitrous or forced induction. The crankshaft features a 24-tooth reluctor wheel, a common setup for many LS1-based engines, ensuring proper sensor readings for your engine management system. This assembly is designed to handle the stresses of high-output builds, making it a solid choice when you're pushing your engine beyond stock capabilities.

Complementing the robust crankshaft are 6.125-inch H-beam connecting rods. These rods are known for their strength and rigidity, and they come equipped with 7/16-inch ARP 8740 bolts, a well-regarded fastener for high-stress applications. The pistons are forged 4032 DSS units with an inverted dome design, featuring a -15cc volume to help achieve your desired compression ratio. They come with plasma-moly file-fit rings, which allow for precise gap setting to match your specific bore and intended use, whether that's street performance or track duty. King XP rod and main bearings are included, offering improved lubrication and wear resistance.

This is a comprehensive rotating assembly intended for builders who need a strong foundation for a performance LS1 engine. It's important to 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 break-in procedures to ensure the longevity of your new engine components.
