About this part

Product Details

This Eagle Pro Street rotating assembly is built for Chevy LS2 and LS3 engines, specifically for naturally-aspirated racing applications. It includes a 3.900-inch crankshaft, 6.125-inch I-beam connecting rods, and 4.000-inch pistons, forming the core of your engine's power delivery system. This assembly is designed to handle the demands of high-performance street and track use where consistent power output is critical.

Eagle has a solid reputation for well-built engine components, and this rotating assembly is no exception. The I-beam connecting rods offer a strong yet lightweight option, balancing durability with the need to reduce reciprocating mass for improved engine response. The crankshaft is forged for strength, ready to withstand the forces generated in a performance LS engine. This kit is a popular choice for builders looking to upgrade their LS2 or LS3 engine for racing or serious performance street applications, providing a reliable foundation for significant power gains.

When building a performance engine, the rotating assembly is a critical choice. This Eagle assembly is designed to be a direct fit for LS2 and LS3 blocks, simplifying the build process. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Ensure you have the necessary supporting components and expertise for installation, as this is a significant engine upgrade.
