About This Product
If you are looking for a valve that can handle the heat of a high-performance build, these AV&V Extreme Duty valves are a top-tier choice. Forged from a single piece of racing-grade stainless steel, they undergo a liquid nitriding process that makes them both smoother and harder than standard factory components. The stems are centerless ground to a micro finish for reduced friction and longevity, featuring a 45-degree angle below the lock groove to prevent seal damage during assembly. Finished in a durable black nitride coating, these are a direct replacement for OEM 18690-02. They provide the reliability needed for demanding street or track use, ensuring your Buell Single, Sportster, Tube frame, or XB top end stays efficient for miles to come.
