KIBBLEWHITE Exhaust Valve - 883/1200 XL 20-20555

Valve durability is non-negotiable in high-performance Harley-Davidson engines, and OEM replacements often fall short under sustained racing conditions. The KIBBLEWHITE Exhaust Valve combines precision engineering with a proprietary nitriding process that outperforms hard chromium and standard nickel plating, delivering superior wear resistance and heat dissipation. Built for both street and strip applications, this stainless-steel valve maintains tight tolerances in cast iron and bronze guides while handling leaded and unleaded fuel seamlessly.
