About this part

Product Details

This Eagle rotating assembly gives you a 3.900-inch stroke crankshaft, 6.125-inch H-beam connecting rods, and 4.030-inch pistons, all balanced and ready to go for your Chevy LS2 or LS3 engine. It's a complete package designed to handle the demands of serious performance applications, including those using nitrous or forced induction. Getting a balanced rotating assembly like this saves you a lot of time and ensures your engine's internals are working together smoothly from the start.

The crankshaft is forged from strong steel, and the H-beam connecting rods are also forged, known for their solid strength and ability to withstand high RPMs and significant cylinder pressures. The pistons are designed to work with the 24-tooth reluctor wheel common on LS2 and LS3 engines. Eagle has a solid reputation for building durable engine components, and this assembly is a popular choice for builders looking to push their LS engine's performance boundaries. This is a well-built foundation for a high-horsepower build.

Because this assembly is balanced, it's ready for installation once you've selected your specific piston rings and bearings, which are not included. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
