About this part

Product Details

Eagle is well-known for building strong internal engine components, and this rotating assembly is a prime example of their commitment to performance. This package is designed for Chevy LS2 and LS3 engines, giving you the core pieces needed to build a serious powerplant. It includes a 3.900-inch crankshaft, 6.125-inch H-beam connecting rods, and 4.060-inch pistons, all balanced and ready to go for demanding applications.

This assembly is engineered for competition use, meaning it's built to handle the stresses of racing, including nitrous and forced induction setups. The H-beam connecting rods are a popular choice for their strength-to-weight ratio, making them suitable for high-RPM operation. The included pistons are sized at 4.060 inches, which, when combined with the 3.900-inch stroke crankshaft, defines the engine's displacement. This is a balanced rotating assembly, which means Eagle has pre-matched the weights of the crank, rods, pistons, and bearings to ensure smooth operation and reduce vibration, a critical step for high-performance builds.

When building a high-performance engine, especially one intended for racing, using a balanced rotating assembly like this from Eagle simplifies the process and ensures a solid foundation. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications and installation instructions for proper assembly and tuning.
