Ready to leave the pack in your dust?

If you're serious about taking your mini bike or go-kart to the next level, you know a simple cam swap isn't enough. Our 1.3 Ratio Solid Cast Racing Shaft Rocker Arm is the next crucial step in your high-performance build. This part is designed specifically for for Predator 212 Non-Hemi, for Honda GX160, for GX200, 196cc, and 224cc engines, and it's fully compatible with popular platforms like for Tillotson and other "clone" motors.

The Real Advantage of the 1.3 Ratio

While standard rockers are a basic 1:1 ratio, our 1.3 ratio design magnifies the cam's lift to achieve a much higher valve lift. This design directly improves valve acceleration and duration, which means better airflow and more power, especially at higher RPMs. It's a proven way to get rid of frustrating "valve float" and unleash the full potential of your high-lift cam.

Built Tough for Race-Day Reliability

Made from a solid cast, high-performance material, our rocker arms are engineered for superior strength and stability. This construction is a significant upgrade from generic alternatives, ensuring your valvetrain stays true and precise even under extreme RPMs. The lighter weight reduces valvetrain mass, helping your engine rev faster and deliver a more responsive feel.

Heads Up: Your Valvetrain is a System

Upgrading to a 1.3 ratio rocker arm will increase your valve lift. For best performance and to prevent issues, we strongly recommend pairing this with heavier valve springs (like 26 lb or higher) to avoid valve float. You may also need shorter pushrods to maintain proper valvetrain geometry depending on your specific build.
