Product Details
This Eagle Pro Street rotating assembly gives you a complete package for your Chevy LS1 engine build, including the crankshaft, connecting rods, and pistons. This assembly is specifically put together for naturally-aspirated racing applications, meaning it's designed to handle the demands of an engine that doesn't use forced induction like a turbo or supercharger. Getting a balanced rotating assembly like this means you're starting with a solid foundation for a high-performance engine.
The crankshaft in this assembly features a 3.900-inch stroke and a 24-tooth reluctor wheel, which is standard for many LS1 applications. Paired with the crankshaft are 6.125-inch I-beam connecting rods. These rods are well-built and suitable for the stresses of racing. The assembly also includes 3.903-inch pistons, which are sized to match the bore and stroke for optimal compression and performance in a naturally-aspirated setup. Eagle is known for putting together reliable rotating assemblies, and this Pro Street kit is a popular choice for builders looking for a balanced and ready-to-install rotating assembly for their LS1.
Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's important to ensure this component meets your local emissions regulations. When installing, proper balancing and clearancing are crucial for the longevity and performance of your engine.
