About this part

Product Details

Eagle is well-known for building strong internal engine components, and this competition rotating assembly is a prime example of their focus on performance. This assembly is designed for Chevy LS2 and LS3 engines, providing a solid foundation for builds intended for racing, including those using nitrous or forced induction. It’s a complete package that brings together key rotating parts to ensure they work together harmoniously.

At the heart of this assembly is a 3.900-inch crankshaft, paired with 6.125-inch H-beam connecting rods. These rods are known for their strength and ability to handle high RPMs and significant cylinder pressures, making them a popular choice for demanding applications. The assembly includes 4.070-inch pistons, ready to be fitted with your preferred rings and pins. A 24-tooth reluctor wheel is also integrated, which is crucial for the engine's computer to accurately read crankshaft position, especially in modern LS engines. This attention to detail in component matching means you're getting parts that are engineered to work together right out of the box.

When building a high-performance engine, especially one that will see track time or significant stress, the rotating assembly is one of the most critical areas to get right. This Eagle assembly offers a well-built, balanced package that simplifies the process of sourcing individual high-performance components. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and balancing procedures.
