Product Details
This Eagle rotating assembly starts with a 3.800-inch stroke crankshaft, a solid foundation for building a powerful LS engine. It's designed for Chevy 4.8L and 5.3L LS engines, specifically those using a 58-tooth reluctor wheel, making it a direct fit for many popular LS applications. The assembly includes 6.125-inch long H-beam connecting rods, known for their strength and ability to handle significant stress, whether you're running naturally aspirated, nitrous, or forced induction setups.
The included pistons are sized for a 3.820-inch bore, completing the rotating assembly. H-beam rods are a popular choice for performance builds because their I-beam shape is reinforced, offering a strong balance of weight and durability. This combination is built to withstand the demands of racing and high-performance street use. Eagle has a reputation for well-built internal engine components, and this assembly is no exception, offering a robust package for those looking to significantly upgrade their LS engine's internals.
When planning your build, remember that this assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Ensure you have all necessary supporting components, such as bearings, rings, and a balanced crankshaft, to complete the installation. This rotating assembly is a critical step towards achieving higher horsepower and torque figures in your LS-powered vehicle.
