About this part

Product Details

This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade the heart of your Chevy LS2 or LS3 engine. You'll receive a 3.800-inch stroke crankshaft, a set of 6.125-inch I-beam connecting rods, and 4.065-inch pistons, all balanced and ready for assembly. This package is specifically put together for naturally-aspirated racing applications, meaning it's built to handle the demands of high-RPM operation without forced induction.

Eagle has a solid reputation for building robust engine components, and this rotating assembly is no exception. The I-beam connecting rods are a strong choice for performance builds, offering a good balance of strength and weight. The crankshaft is forged to handle the stresses of racing, and the included pistons are sized to match the bore and stroke for optimal compression and performance. This assembly is balanced, which is a critical step that saves you time and ensures smoother engine operation and longevity. Proper balancing reduces vibration and wear on bearings and other internal components.

When putting together an engine like this, it's important to have all your supporting components ready. You'll need to source your own main bearings, rod bearings, piston rings, wrist pins, and any necessary assembly lubricants. Always refer to the manufacturer's detailed installation instructions and torque specifications to ensure a proper build. Keep in mind that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations.
