About this part

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 to work with 58-tooth reluctor wheels, common in many 4.8L and 5.3L LS applications, making it a versatile choice for engine rebuilds or performance upgrades. The assembly includes 6.125-inch long H-beam connecting rods, known for their strength and ability to handle increased cylinder pressures, especially when paired with nitrous or forced induction setups. These rods connect to 3.820-inch bore pistons, completing the core of the rotating assembly.

Eagle has a reputation for well-built engine components, and this competition-grade assembly is no exception. The H-beam rods are forged for strength, providing a robust link between the pistons and the crankshaft. This combination is engineered to withstand the demands of racing, including the significant stress from nitrous oxide injection or turbocharging. When you're aiming for serious power gains and reliability under extreme conditions, a balanced and strong rotating assembly like this is crucial for the longevity of your LS engine.

This assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's important to ensure all components are properly balanced and installed according to manufacturer specifications for optimal performance and durability. If you're building a high-performance LS engine for racing or demanding street applications, this Eagle rotating assembly offers a strong starting point.
