Black Diamond™ Valve Kit – KIBBLEWHITE (Manufacturer's part number: 20-22500)
This Black Diamond™ valve kit includes the necessary components to replace the intake and exhaust valves on vintage and touring engines. The heads and stems benefit from a localized strengthening process (0.002" deep with a surface layer of 0.0002"), a treatment that enhances wear properties, reduces friction, and offers increased resistance to corrosion and wear. Made in the USA, this kit is compatible with both leaded and unleaded fuels.
Ideal for riders looking for a robust replacement part for vintage cylinder heads — particularly for Harley-Davidson 1340 (1983) models such as FXWG Wide Glide, FXS Low Rider, and FXR Super Glide II. A relevant choice for engine maintenance, restoration, or refurbishment of cylinder heads.
