This is the Eagle Chevy 4.8/5.3 LS Pro Street rotating assembly, part number 637713898.

Eagle is known for putting together robust rotating assemblies, and this Pro Street kit is no exception. The I-beam connecting rods offer a good balance of strength and weight for racing use, while the included pistons are sized for a 3.898-inch bore.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. You'll want to ensure you have all the necessary supporting components for your engine build, such as bearings, rings, and a proper gasket set, which are typically sold separately. Refer to the manufacturer's installation instructions for detailed assembly and balancing procedures.
