About this part

Product Details

This Eagle Pro Street rotating assembly gives you a solid foundation for your Chevy 4.8L or 5.3L LS engine build. What you get in this package is a precisely balanced rotating assembly, featuring a 3.800-inch stroke crankshaft, a 58-tooth reluctor wheel, 6.125-inch I-beam connecting rods, and 3.780-inch bore pistons. This assembly is designed to handle the demands of naturally-aspirated racing applications, providing the core components needed to rebuild or upgrade your engine's bottom end.

Eagle has put together a well-built package here, focusing on strength and reliability for performance builds. The I-beam connecting rods are a popular choice for their balance of strength and weight, suitable for engines that will see hard use. The included crankshaft is forged for durability, and the pistons are sized to match the bore and stroke for optimal compression and performance. This assembly comes balanced, which is a critical step in ensuring your engine runs smoothly and lasts longer, reducing vibration and stress on other components.

When undertaking an engine build of this caliber, it's important to have all your supporting components ready. This rotating assembly is the heart of your engine's power delivery, so ensure you have quality bearings, rings, and gaskets to complete the installation. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper assembly and break-in procedures to get the most out of your new rotating assembly.
