About this part

Product Details

This Eagle Competition Rotating Assembly starts with a 4.000-inch forged 4340 crankshaft, a solid foundation for building a powerful LS engine. It's specifically designed for Chevy LS 4.8L and 5.3L applications and includes a 24-tooth reluctor wheel, making it ready for many factory and aftermarket ECU setups. This assembly is built to handle the demands of racing, including the extra stress from nitrous oxide or forced induction systems.

The connecting rods are 6.125-inch long H-beams, known for their strength and reliability under high RPM and load. They are secured with 7/16-inch ARP 8740 bolts, a popular choice for their durability and consistent clamping force. Paired with these rods are DSS forged 4032 pistons, featuring a -5cc flat top design and a 3.810-inch bore size. These pistons are fitted with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing in your specific build. King XP rod and main bearings are included, offering robust protection for critical rotating components.

This rotating assembly is a well-built package for those looking to significantly upgrade their LS engine for competition. 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.
