About this part

Product Details

This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade your Chevy 4.8L or 5.3L LS engine. You get a 3.900-inch stroke crankshaft, 6.125-inch I-beam connecting rods, and 3.780-inch pistons, all designed to work together as a balanced unit. This assembly is specifically intended for naturally-aspirated racing applications, meaning it's built to handle the demands of engines that don't use forced induction like turbochargers or superchargers.

Eagle has a solid reputation for well-built 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 included pistons are sized for a 3.780-inch bore, common for many LS applications. When you're putting together a performance engine, having a balanced rotating assembly from the start saves you a lot of guesswork and ensures the internal components are matched for optimal performance and durability under racing conditions. This assembly is designed to be a direct fit for the specified LS engines, simplifying the rebuild process.

It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications and installation instructions to ensure proper fitment and assembly procedures for your specific project. Proper balancing and installation are critical for the longevity and performance of any rotating assembly.
