KPM Gaskets for Valve Stems

Valve guide are press fit on the valve guides. Due to the variety of stock and aftermarket valve guides it may be necessary to grind the guide for proper fitment.

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.

KPM Cast Iron Valve Guides

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 Seats for Unleaded Fuel

Casting a valve seat with the combination of alloys required for today’s fuels is not possible, and only the so-called Powdered Metal Technology facilitates to blend these alloys creating a high density seat with exceptional wear resistance, machinability, and thermal qualities. The KPM valve seats are made from such materials which provide good uniform hardness and resistance to microwelding, wear, and recession. They are compatible with all types of fuel blends, resists corrosion and burning, and are machinable with standard tooling. They have been thoroughly tested on the track and street, in high RPM multi-valve applications, high spring load V-twin applications, with leaded and unleaded gasoline, ethanol and methanol. In each case they have performed flawlessly, making them the seats of choice for cylinder head builders everywhere.

Valve Collars for Big Twin Flathead

For all Big Twin Flatheads from 1937–48. The complete kit comprises four lower and four upper valve collars and four spacers for the upper valve collars.

KPM Drivers for Valve Stem Seals

Professional quality drivers for OEM-type seals which will last forever if used as intended. The tools are designed for precision fitment onto the seal OD to help the builder center the seal over the valve guide so that a few light strikes from a hammer will set the seal. Radiused top striking surface reduces the likelihood of a burr forming from deformation. Each installation tool is color coded and laser marked for each seal size by guide diameter.

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).
