KIBBLEWHITE Exhaust Valve - XL 20-4197

Kibblewhite's XL 20-4197 exhaust valves are engineered for engines that demand superior durability and reliability under extreme conditions. The stellite-tipped, nitrided construction delivers exceptional wear resistance and corrosion protection—critical for high-performance applications where stock valves fall short. Built in the USA with precision tolerances, these one-piece stainless-steel valves minimize friction, maximize heat dissipation, and maintain consistent sealing across thousands of combustion cycles.
