About this part

Product Details

This Eagle rotating assembly starts with a 3.900-inch stroke crankshaft, a solid foundation for building a powerful LS2 or LS3 engine. The crankshaft is paired with 6.125-inch long H-beam connecting rods, known for their strength and reliability under high stress. These rods connect to 4.070-inch bore pistons, bringing the total displacement up for increased power potential.

Designed for the rigors of competition, this assembly is built to handle demanding applications like racing, including those using nitrous oxide or forced induction. The H-beam connecting rods offer a strong, well-built option that can withstand the increased cylinder pressures and forces associated with these power-adder setups. The 58-tooth reluctor wheel is standard for many LS engines, ensuring compatibility with your engine management system.

This complete rotating assembly includes the crankshaft, connecting rods, and pistons, simplifying your engine build process. It's a critical set of components that work together to convert the up-and-down motion of your pistons into the rotational force that drives your vehicle. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
