KIBBLEWHITE Exhaust Valve 20-20925

Exhaust valves endure extreme thermal and mechanical stress—factory units wear quickly under high-RPM racing conditions. The KIBBLEWHITE 20-20925 combines stainless-steel construction with a stellite tip and proprietary nitrided surface treatment, delivering superior wear resistance and longevity compared to hard-chromed alternatives. Built for serious racers and rebuild enthusiasts, this valve maintains tight tolerances and reduces friction, ensuring reliable performance across both leaded and unleaded fuel applications.
