18024-87 Extreme Duty Valves

These AV&V extreme duty valves are a significant upgrade over stock components, designed to replace OEM part number 18024-87. Each valve is one-piece forged from a racing-grade stainless steel alloy and finished with a liquid nitriding process. This black nitride coating creates a surface that is both smoother and stronger than traditional valves, reducing friction and wear. The stems are centerless ground to a micro finish for maximum longevity and feature a 45-degree angle below the lock groove to make valve seal installation a breeze. These high-performance valves fit Sportster, Buell RS, Single, Tube frame, and XB models, providing the durability needed for high-stress engine environments.
