Starting with a 3.900-inch stroke forged crankshaft, this Eagle rotating assembly is built for serious performance in Chevy LS2 and LS3 engines. The 6.125-inch long H-beam connecting rods are forged from strong steel, designed to handle the stresses of racing, including nitrous and forced induction applications. Paired with 4.030-inch bore pistons, this assembly gives you a solid foundation for a high-output engine build.

Eagle has a reputation for well-built engine components, and this rotating assembly is no exception. The crankshaft features a 24-tooth reluctor wheel, which is standard for many LS-based engines, ensuring compatibility. The H-beam rod design is a popular choice for its strength-to-weight ratio, making it suitable for demanding use where reliability is key. This assembly is intended for competition use, meaning it's engineered to withstand higher RPMs and increased cylinder pressures compared to stock components.

When building a performance LS engine, the rotating assembly is one of the most critical pieces. This Eagle kit includes the crankshaft, connecting rods, and pistons, giving you a matched set to simplify your build. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer specifications for detailed installation procedures and recommended clearances.
