This Eagle Pro Street rotating assembly gives you the core components needed to rebuild or upgrade the bottom end of your Chevy 4.8L or 5.3L LS engine. You'll receive a 3.900-inch stroke crankshaft, 3.810-inch pistons, and 6.125-inch I-beam connecting rods, along with the necessary rings. This assembly is specifically put together for naturally-aspirated racing applications, meaning it's built to handle the demands of high-RPM operation without forced induction.

The crankshaft is forged from durable steel and features a 3.900-inch stroke, which is a common upgrade for LS engines to increase displacement and power potential. The 6.125-inch I-beam connecting rods are well-built for strength and reliability under racing conditions. The included pistons are designed to work with this specific combination, featuring a 3.810-inch bore size. This assembly is a solid starting point for building a performance LS engine where consistent power and durability are key.

It's important to note that this rotating assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always consult with your engine builder or refer to Eagle's detailed specifications for proper installation and balancing procedures to ensure optimal performance and longevity for your racing build.
