Kibblewhite has researched, tested and chemically separated several cast iron blends, and ultimately specified a combination of ingredients to meet the needs of Harley-Davidson engines. KPM material includes specific amounts of key elements such as carbon, silicon, manganese, nickel, copper and sulfur to create a highly pearlitic structure wit dense fine grains for excellent wear resistance. This "recipe" also allows for a superior surface fnish in the guide bore that is easy on valve stems.

KPM Valve Stem Seal Installation Caps
Plastic caps for a smooth and safe installation of your new valve stem seals. Three sizes available: green=5/16” (all Evos + intake ironhead Sportster), yellow=11/32” (exhaust only ironhead Sportster), red=3/8” (Pans + Shovels).
KPM Black Diamond Valves
Kibblewhite Black Diamond valves are CNC machined from one-piece forgings of EV8 stainless steel. The proprietary Black Diamond multi-stage process treats the shaft to a depth of 0.002” creating a hard, smooth and corrosion resistant surface that cannot flake crack or peel off. The valve tips feature welded-on stellite tips for improved resistance to the impact and abrasive wear of the rocker arms. All versions work with modern lead-free fuels.
