Product Details
This is the Eagle Chevy LS2 4.125 inch crankshaft, 6.125 inch H-beam connecting rod, and 4.010 inch piston rotating assembly. This is a competition-level assembly designed for serious engine builds where increased displacement and strength are key. It's built around a robust 4.125 inch stroke crankshaft, paired with strong 6.125 inch H-beam connecting rods, and topped off with 4.010 inch pistons. This combination is a popular choice for LS2-based engines looking to achieve significant power gains and improved durability under demanding conditions.
The crankshaft in this assembly is forged from high-strength steel, providing the backbone for high-horsepower applications. The H-beam connecting rods are also forged, offering a significant strength improvement over stock components, which is crucial for handling the increased stresses of a larger displacement or boosted engine. The included pistons are designed to match the bore size and compression ratio requirements for a typical LS2 build, ready to be fitted with your chosen piston rings and wrist pins. This assembly is balanced to reduce vibration and ensure smooth operation at higher RPMs.
When building a high-performance LS2 engine, a well-matched rotating assembly is critical for reliability and power. This Eagle assembly takes the guesswork out of selecting compatible, strong components. Please note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to manufacturer specifications for detailed installation procedures and recommended components.
