Product Details
Starting with a 4.125-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, essential for proper engine management on many Chevy LS platforms. This assembly is designed to handle the stresses of high-output engines, making it a solid foundation for a performance build.
Complementing the robust crankshaft are 6.125-inch H-beam connecting rods, known for their strength and reliability under load. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their durability and consistent clamping force. The pistons are forged from 2618 aluminum, a material chosen for its ability to withstand high temperatures and pressures. These are flat-top pistons with a -4.6cc dish, designed for a 4.155-inch bore, and come with plasma-moly file-fit rings, allowing for precise gap setting during installation. King XP rod and main bearings are included, offering excellent wear resistance and performance in demanding conditions.
This is a comprehensive rotating assembly intended for builders who need a well-matched set of components for a high-performance Chevy LS7 engine. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
