About this part

Product Details

If you're building a high-performance Chevy LS2 engine for serious racing, especially with nitrous or forced induction, this Eagle competition rotating assembly is a solid foundation. It bundles together the core components you need to handle significant power and stress, saving you the hassle of sourcing each piece individually.

At the heart of this assembly is a 4.000-inch forged 4340 steel crankshaft with a long snout, designed for durability under extreme conditions. It's paired with 6.125-inch I-beam connecting rods, which are known for their strength and reliability in performance applications. These rods use 7/16-inch ARP 8740 bolts, a popular choice for their robust clamping force. The pistons are forged 4032 aluminum from Mahle, featuring an inverted dome design with a -12cc dish, and come with plasma-moly file-fit rings. This piston and ring combination is designed to work well with boosted or nitrous applications, helping to manage combustion pressures. The assembly also includes King XP rod and main bearings, which offer improved performance and durability over standard bearings.

This is a competition-grade assembly, meaning it's built to withstand the rigors of racing. Keep in mind that this part is not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have all the necessary supporting components and follow the manufacturer's installation guidelines carefully.
