TITANIUM RETAINERS
KPMI uses U.S. mill certified titanium bar for our retainers. KPMI Titanium Retainers are engineered using advanced Finite Element Analysis (FEA) software. FEA stress analysis allows our engineers to lighten the retainer without sacrificing strength. All KPMI retainers are inspected to insure exact fitment on the valve and on the spring. Correct fitment promotes longer component life and optimizes the performance of the entire valvetrain.

BLACK DIAMOND VALVES
All KPMI Black Diamond™ stainless steel valves are impregnated by a special German process to a depth of .002”, with a surface build up of .0002”. This “Black Diamond™” process improves wear properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and nickel electrolysis plating. Each valve is designed using Finite Element Analysis software, and profiles are tested on our computerized flow bench. Black Diamond™ Valves are light, strong, one piece forgings with profiles that provide excellent flow characteristics.

TAPPETS
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.

Viton® VALVE GUIDE SEALS
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.
