About this part

Product Details

Eagle is well-known for building strong rotating assemblies, and this Chevy LS2 competition rotating assembly is a prime example of their work. If you're building a high-performance LS2 engine for racing, especially with nitrous or forced induction, this kit has the core components you need to get started. It's designed to handle the stresses of demanding applications.

At the heart of this assembly is a 4.000-inch forged 4340 crankshaft, chosen for its strength and durability under high loads. It's paired with 6.125-inch H-beam connecting rods, which are also forged from 4340 steel and secured with 7/16-inch ARP 8740 bolts, offering a solid connection between the crank and pistons. The pistons are forged from 2618 aluminum with an inverted dome design, featuring a -27.5cc volume and a 4.030-inch bore size, ready for plasma-moly file-fit rings. This combination is built to withstand significant power increases.

This assembly includes King XP rod and main bearings, providing reliable lubrication and reduced friction for the rotating components. It also features a 24-tooth reluctor wheel, essential for proper engine management in many LS2 applications. Please note that this assembly is not CARB approved and cannot be shipped to California. It's a robust starting point for a serious engine build.
