  1. Custom Kibblewhite Valves - (Click to Open)

    Custom Valve Design Options

    • Stellite Tips for Rocker Applications

      Stellite is welded to the valve tips in rocker actuated applications for resistance to the impact and abrasive wear common in rocker arm systems. This welded stellite can never come loose.

    • Valve Material

      • Black Diamond®

        Kibblewhite Black Diamond® one pieced forged stainless steel valves are impregnated by a special German process to improve wear properties and reduce friction. This process provides resistance to corrosion and wear that is superior to that of hard chromium and electrolysis nickel plating.

      • Tensilite®

        Kibblewhite Tensilite® titanium valves are one piece forgings made from 6AL4V or 6-2-4-2 titanium alloy. These are the latest developments in titanium valve alloys and have superior hardness, strength, and thermal characteristics when compared to other titanium valve alloys. Tensilite® valves are covered with a chromium nitride (CRN) PVD coating. This coating adheres exceptionally well to titanium, has a low coefficient of friction, and is impact, abrasion, and corrosion resistant.

      • White Diamond®

        We fully CNC machine our Kibblewhite White Diamond® valves from a one-piece forging of either EV8 Stainless Steel or Inconel-751. These materials have proven heat and corrosion resistance properties and are hard chromed with a 360 degree anode to produce the highest possible grade of hard chrome finish.

  2. Custom Kibblewhite Valve Seats - (Click to Open)

    Custom Seat Design Options

    • Custom Seat Material Options

      • Powdered metal seats

        With the latest in powdered metal technology, KPMI’s R&D team was able to create a high density seat with exceptional wear resistance, resistance to micro welding, and good thermal qualities. This material is compatible with all types of fuel blends, resists corrosion and burning, and is machinable with standard tooling. See the Kibblewhite Seats Section in back of catalog for full selection.

      • Nickel aluminum bronze seats

        The product of a two year KPMI R&D effort, this proprietary high copper, beryllium free bronze alloy is designed specifically for use with titanium valves in high performance applications. See the Kibblewhite Seats Section in back of catalog for full selection.

  3. Custom Kibblewhite Valve Guides - (Click to Open)

    Custom Guide Design Options

    • Tight Tolerances

      High concentricity tolerances are held to insure the best possible geometry between the seat and guide is maintained when the guides are replaced. This means minimal material removal from the seat, time savings, and consistent chamber volumes, when valve jobs are performed.

    • Custom Guide Material Options

      • C630 bronze guides

        C630 is a blend of copper, nickel, and aluminum. The high copper content gives excellent thermal qualities, the nickel makes the guide tough and wear resistant, and the aluminum brings work hardening characteristics. This bronze alloy allows for tighter clearances than other materials, creating better valve and seat sealing, as well as superior oil control. The expansion qualities of C630 bronze make it especially compatible with aluminum cylinder heads.

      • Cast iron guides

        KPMI R&D has produced a proprietary cast iron blend that thrives in the tough operating conditions of today’s engine. KPMI’s certified cast iron provides excellent wear resistance and a superior guide bore finish that is easy on valve stems.
