This rotating assembly is a significant step up for anyone looking to build a more powerful and reliable engine.

When installing this rotating assembly, proper balancing is crucial for engine longevity and smooth operation. It's recommended to have the entire assembly professionally balanced by a reputable machine shop to match your specific application and intended use. Ensure all components are clean and properly lubricated during installation, following manufacturer guidelines. This assembly is not CARB approved and cannot be shipped to California.
