Valve Black Diamond™ – KIBBLEWHITE (Ref. 20-20910)

Its Stellite tip and special nitriding treatment (depth of .002" with a surface layer of .0002") increase wear resistance while reducing friction compared to traditional finishes such as hard chrome or electrolytic nickel plating.

This lightweight valve features profiles designed to promote good flow in the cylinder head while remaining compatible with cast iron or bronze guides with low tolerances, for optimal oil control and effective heat dissipation. Made in the USA, it fits several Harley-Davidson Softail models from 2004 (e.g. FXSTSI, FXSTI, FXSTDI), and integrates perfectly into Roadster, Touring, and Classic projects.
