Product Details
If you're building a high-performance naturally-aspirated engine for racing, a strong rotating assembly is the heart of the operation. This Eagle Pro Street rotating assembly is designed specifically for Chevy LS2 and LS3 engines, providing a solid foundation for serious power. It's a complete package that brings together the essential components needed to get your engine rotating reliably under demanding conditions.
This assembly features a 3.900-inch stroke crankshaft, which is a popular choice for LS engines looking to increase displacement and torque without going to an extreme stroke length. Paired with it are 6.125-inch I-beam connecting rods. I-beam rods are well-built and a common choice for performance applications, offering a good balance of strength and weight. The assembly also includes 4.005-inch pistons, which are sized to match the bore and stroke for optimal compression and combustion. Everything here is balanced and ready to be installed, saving you time and ensuring component compatibility.
It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Ensure you check all local regulations regarding engine modifications. This rotating assembly is a critical piece for any LS-based build aiming for naturally-aspirated racing performance, providing the durability and precision you need to compete.
