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 3.800-inch stroke crankshaft, 6.125-inch I-beam connecting rods, and 4.070-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 producing well-built engine components, and this rotating assembly is no exception. The I-beam connecting rods offer a strong yet lightweight option, crucial for reducing reciprocating mass and allowing the engine to rev more freely. The crankshaft is forged for durability, ensuring it can withstand the significant forces generated during combustion. The included pistons are sized for a 4.070-inch bore, a common size for LS engine builds looking to increase displacement.

This assembly is a popular choice for builders aiming for improved performance in naturally aspirated LS engines. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and tuning to ensure optimal performance and longevity.
