Product Details
Starting with a 4.000-inch forged 4340 steel crankshaft, this Eagle rotating assembly is built for serious performance in your Chevy LS3 engine. The crankshaft features a 58-tooth reluctor wheel, essential for proper engine management in many LS applications. This assembly is designed to handle the demands of racing, including the extra stress from nitrous and forced induction setups.
The 6.125-inch H-beam connecting rods are forged from 4340 steel and secured with 7/16-inch ARP 8740 bolts, offering exceptional strength and reliability under high loads. Complementing the crank and rods are forged 4032 DSS pistons, featuring a -5cc flat top design and a 4.065-inch bore size. These pistons come with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. King XP rod and main bearings are included, providing robust lubrication and wear resistance for the critical rotating components.
This is a comprehensive package for anyone rebuilding or significantly upgrading their LS3 engine for competitive use. Please 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.
