About this part

Product Details

This is the Eagle Chevy LS 4.8/5.3 rotating assembly, designed for serious performance builds. It includes a 4.000-inch forged 4340 crankshaft, 6.125-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, and 3.800-inch forged 4032 DSS pistons with an inverted dome. This assembly is built to handle the demands of racing, including nitrous and forced induction applications.

The forged 4340 steel crankshaft is a strong foundation for high-horsepower engines, and the 24-tooth reluctor wheel is specific for LS engine management systems. The H-beam connecting rods are well-built for durability under stress, paired with ARP bolts for secure attachment. The included pistons feature an inverted dome design, which helps achieve a specific compression ratio when combined with the crankshaft and rod length. They also come with plasma-moly file-fit rings, allowing for precise gap setting during installation to optimize performance and sealing.

This rotating assembly also includes King XP rod and main bearings, known for their robust construction and ability to handle high loads. This comprehensive package is ideal 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. Always refer to manufacturer instructions for proper installation and assembly procedures.
