About this part

Product Details

Starting with a 4.000-inch forged 4340 steel crankshaft, this Eagle rotating assembly is built for serious performance. It features a 24-tooth reluctor wheel, essential for proper engine management on LS3 applications. This assembly is designed to handle the demands of racing, including the stresses of nitrous and forced induction setups, making it a solid foundation for a high-performance engine build.

The 6.125-inch H-beam connecting rods are forged from 4340 steel and come equipped with 7/16-inch ARP 8740 bolts, known for their strength and reliability under high loads. Paired with these rods are 4.075-inch forged 4032 aluminum pistons. These pistons have a -5cc dish, which helps achieve a specific compression ratio when combined with your cylinder heads. They also include plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. King XP rod and main bearings are included, offering robust protection for critical rotating components.

This complete rotating assembly is a popular choice for engine builders looking to push the limits of their Chevy LS3. While it's designed for competition, remember that it is not CARB approved and cannot be shipped to California. Ensure you have the necessary supporting components and expertise for installation to get the most out of this powerful assembly.
