Product Details
This Eagle rotating assembly starts with a 4.000-inch forged 4340 crankshaft, a strong foundation for high-performance LS engines. It's designed for the 24-tooth reluctor wheel found in 4.8L and 5.3L LS applications, making it a direct fit for many popular GM vehicles. The crankshaft's robust construction is built to handle the demands of racing, including nitrous and forced induction setups.
Complementing the crank are 6.125-inch H-beam connecting rods, known for their strength and reliability under stress. These rods are secured with 7/16-inch ARP 8740 bolts, a well-regarded choice for their durability. The assembly includes forged 4032 pistons with an inverted dome design, measuring 3.800 inches in diameter and featuring a -15cc dish. These pistons are paired with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. King XP rod and main bearings are included, offering excellent wear resistance and smooth operation.
This comprehensive rotating assembly is a solid choice for anyone rebuilding or upgrading their LS engine for competitive use. Please note that this assembly is not CARB approved and cannot be shipped to California. It's recommended to consult manufacturer instructions for proper installation and any additional components required for your specific build.
