Product Details
This Eagle rotating assembly kit is built around a 4.000-inch stroke forged 4340 crankshaft, a solid foundation for a high-performance LS engine build. It's designed for Chevrolet 4.8L and 5.3L LS engines, and the 24-tooth reluctor wheel is standard for most LS applications. This kit is a popular choice for those looking to significantly upgrade their engine's internal strength, especially for racing applications that might involve nitrous or forced induction.
The kit includes 6.125-inch H-beam connecting rods, which are known for their strength and reliability under stress. These rods are secured with 7/16-inch ARP 8740 bolts, a well-regarded fastener for high-stress engine components. Complementing the crank and rods are DSS forged 4032 pistons with a -15cc inverted dome, designed for a 3.800-inch bore. These pistons are paired with plasma-moly file-fit rings, allowing for precise gap setting to match your specific build and ensure optimal sealing. King XP rod and main bearings are also included, offering robust lubrication and wear resistance for critical rotating parts.
This assembly is a comprehensive package for rebuilding or significantly enhancing the bottom end of your LS engine. It's important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and assembly procedures to ensure the longevity and performance of your new rotating assembly.
