About this part

Product Details

This Eagle Competition Rotating Assembly is built for serious performance, especially if you're planning on using nitrous or forced induction. What you get in this kit is a complete package designed to handle the demands of high-horsepower LS2 engines. It includes a 4.000-inch forged 4340 crankshaft, which is a strong foundation for your build. You also get 6.125-inch H-beam connecting rods, known for their robust design, secured with 7/16-inch ARP 8740 bolts. The pistons are forged 2618 CP units with an inverted dome, measuring 4.005 inches in bore size and featuring a -27.5cc volume, paired with plasma-moly file-fit rings for a precise seal.

This assembly is configured for a 58-tooth reluctor wheel, common in many LS applications. To ensure smooth operation and durability, it comes complete with King XP rod and main bearings. The 4340 forged steel crankshaft and the H-beam connecting rods are well-built to withstand the stresses of racing and boosted applications. The forged pistons are designed for strength and efficient combustion. This is a comprehensive rotating assembly, meaning all the core internal engine components work together as a balanced unit, ready for installation into your LS2 block.

When putting this assembly together, remember that the plasma-moly rings are file-fit, which means they need to be gapped to your specific cylinder bore for optimal performance and sealing. This level of customization is typical for high-performance engine builds. Please be aware that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper assembly and break-in procedures to get the most out of this competition-grade rotating assembly.
