Eagle Chevy LS1 3.900in Crank 24 Tth Reluctor 6.125in I-Beam Rods 3.913in Pistons Rotating Assembly

Eagle is well-known for building strong internal engine components, and this Pro Street rotating assembly is a prime example of their commitment to performance. This assembly is specifically put together for naturally-aspirated racing applications, meaning it’s designed to handle the demands of engines that don't use forced induction like turbochargers or superchargers. If you're building a high-performance LS1 engine for the track or serious street use where maximum power is the goal, this rotating assembly is a solid foundation.

At the heart of this assembly is a 3.900-inch stroke crankshaft, paired with 6.125-inch I-beam connecting rods. These rods are a popular choice for their balance of strength and weight, making them suitable for high-RPM operation. The assembly also includes 3.913-inch pistons, which are sized to work with the crank and rods to achieve the desired displacement and compression ratio for your LS1 build. The 24-tooth reluctor wheel is standard for most LS1 applications, ensuring compatibility with your engine's computer system. This is a well-built package designed to give your LS1 engine the robust internals it needs to perform under pressure.

When undertaking a build of this caliber, it's important to ensure all components are properly balanced and clear the cylinder walls and block. While this assembly is designed for performance, please note that it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation guidelines for proper assembly and torque specifications to ensure the longevity and performance of your engine.
