Valve White Diamond® by KIBBLEWHITE (manufacturer part no: 80-80214H): a machined intake valve for demanding quad, enduro, and motocross riders. CNC designed from a single forged piece of EV8 stainless steel or Inconel-751, it features a surface treatment through electroplating with a 360° anode for a uniform hard chrome coating.
Designed for competition engines and demanding revs, this White Diamond® valve adheres to Kibblewhite's standards for precision machining. The base material (EV8 or Inconel-751) and hard chrome provide a smooth and even surface, suitable for the high thermal and mechanical stresses encountered off-road.
Important note: installation requires the use of the appropriate Kibblewhite spring kit — do not install without the recommended kit.
