About This Product
This Kibblewhite Black Diamond exhaust valve is a premium standard size replacement for Ironhead Sportsters.

Like all Black Diamond valves, it is a one-piece stainless steel forging with a black nitrided finish, providing excellent heat resistance and durability in the demanding exhaust environment.
