About this part

Product Details

This Eagle Pro Street rotating assembly is built for Chevy 4.8L and 5.3L LS engines, specifically designed for naturally-aspirated racing applications. It’s a well-built package that includes a 3.800-inch crankshaft, 6.125-inch I-beam connecting rods, and 3.780-inch pistons, all balanced and ready for installation. This assembly is a solid foundation for building a powerful engine that can handle the demands of the track.

The Pro Street rotating assembly from Eagle is a popular choice for builders looking to get more performance out of their LS engine without going forced induction. The I-beam connecting rods are strong and reliable for racing use, and the included pistons are sized to match the crankshaft and bore for optimal performance. When you're putting together a naturally-aspirated race engine, having a balanced rotating assembly like this saves you a lot of time and ensures the critical internal components work together harmoniously. This means less vibration and a more consistent power delivery when you're on the throttle.

This assembly is designed to fit specific Chevy LS applications, so it's important to confirm your engine's bore and stroke requirements match the specifications of this kit. While it's built for performance, remember that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation guidelines for proper assembly and balancing procedures to ensure the longevity and performance of your engine build.
