Eagle Chevy LS3 4.000in Crank 58 Tth Reluctor 6.125in I-Beam Rods 4.070in Pistons Rotating Assembly

Starting with a 4.000-inch stroke forged crankshaft, this Eagle rotating assembly is built for serious Chevy LS3 builds. The crankshaft is forged from 4340 steel, a strong material chosen for its ability to handle high stress and heat, making it a solid foundation for a performance engine. It also features a 58-tooth reluctor wheel, which is standard for most LS engines, ensuring compatibility with your factory or aftermarket ECU.

Paired with the crankshaft are 6.125-inch long I-beam connecting rods, also forged from 4340 steel. The I-beam design offers a good balance of strength and weight, suitable for a wide range of performance applications. These rods are designed to work with 4.070-inch bore pistons, which are included in this assembly. The pistons are typically hypereutectic or forged aluminum, chosen for their lightweight properties and ability to withstand combustion pressures. This combination of a strong crank, robust rods, and appropriately sized pistons creates a well-balanced rotating assembly that’s ready to be installed.

This assembly includes the crankshaft, connecting rods, and pistons, giving you a significant portion of your engine's internal components in one package. It's important to note that this assembly is not CARB approved and cannot be shipped to California. For a complete engine build, you'll need to source bearings, piston rings (if not pre-gapped or installed), and gaskets separately. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
