Eagle Chevy LS2/LS3 3.900in Crank 58 Tth Rlctor 6.125in H-Beam 6cc 4.065in Pistons Rotating Assembly

This is the Eagle Chevy LS2/LS3 rotating assembly, a complete package designed to build a high-performance engine for your Chevrolet LS2 or LS3 vehicle. It includes a 3.900-inch stroke crankshaft, 6.125-inch H-beam connecting rods, and 4.065-inch pistons, all balanced and ready for installation. This assembly is engineered for the rigors of racing, including applications using nitrous oxide or forced induction, meaning it's built to handle significant power increases and demanding conditions.

The heart of this assembly is the Eagle 4340 forged steel crankshaft, known for its strength and durability under extreme stress. Paired with Eagle's 4340 forged H-beam connecting rods, which feature robust construction for high-RPM operation and heavy loads, this setup provides a solid foundation for boosted or nitrous-fed engines. The included pistons are designed to work with a 6cc combustion chamber volume, contributing to a specific compression ratio when paired with appropriate cylinder heads. This rotating assembly comes balanced, saving you a critical step in the engine building process and ensuring smoother operation and reduced vibration.

When building a powerful LS engine, the rotating assembly is one of the most critical components. This Eagle assembly offers a well-matched set of parts from a reputable manufacturer, simplifying the process of sourcing individual high-performance engine components. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder and the manufacturer's instructions for proper installation and any additional components required for your specific build, such as bearings, rings, and gaskets.
