(4) All KPMI Black Diamond Stainless Steel Valves are impregnated by a special German process to .002" deep with a .0002" surface build-up to improve wear properties and reduce friction. This process provides resistance to corrosion and wear that is superior to that developed by hard chromium and electrolysis nickel plating. These valves are light and the profiles provide excellent flow characteristics.
(3) We choose to use C63000 nickel bronze as a material to make valve guides because of its ideal characteristics for the application. The 4-5 percent nickel content produces superior resistance to wear, and the approximately 80 percent copper content delivers outstanding heat conductivity.
KPMI Red 100% Viton® valve stem seals are designed to have optimum fitment,
allow for maximum lift, and to give maximum life. KPMI Red valve stem seals
are resistant to high temperatures, petroleum products and the corrosive gasses that are the
by-products of combustion. These seals retain their ability to seal in situations where other materials could harden and allow oil to enter the combustion chamber causing detonation, carbon build up and a loss of power.
The Red Ones are truly the racer’s choice.
KPMI engineers design our tappets using advanced finite element stress analysis software. This software allows our engineers to lighten the tappets without sacrificing strength, so we can create the strongest, lightest tappets possible. These tappets are machined from aircraft quality solid steel bar stock. They undergo a proprietary heat treatment process that creates a hard surface and a non-brittle core, maximizing toughness and wear resistance. KPMI tappets are run in high performance automotive and motorcycle racing applications including Motocross, Flat Track Racing, Road Racing, Drag Racing, and Land Speed Racing at the Bonneville Salt Flats.
