Description
Exhaust valves are critical to engine reliability and performance—a worn or marginal valve compromises combustion efficiency, increases heat stress, and accelerates internal wear. The KIBBLEWHITE Black Diamond™ 30-30090 exhaust valve delivers the durability and precision you need to maintain peak power output and extend engine life, whether you’re running a high-revving race engine or a meticulously maintained street build. By reducing friction and resisting corrosion at extreme temperatures, this one-piece forging ensures consistent sealing and repeatable performance lap after lap.
