KPMI Bronze Valve Guides:

We choose to use C630 nickel bronze as a material to make valve guides because of its ideal characteristics for the application. The 4-5 percent nickel content provides superior resistance to wear, and the approximately 80 percent copper content delivers outstanding heat conductivity. Guide profiles are designed to have minimal effect on the airstream while maintaining critical cross sectional thickness in high temperature areas, promoting high performance and endurance. The top portion of the guides are shortened when cam lift information available at the time of design shows that additional retainer to seal clearance is required.

KPMI Cast Iron Valve Guides:

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

KPMI Valve Stem Seals “The Red Ones”:

KPMI Red 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 by-products of combustion. They retain their ability to seal in situations where other materials could allowoil to enter the combustion chamber causing detonation, carbon build up and a loss of power. The Red Ones are truly the racer’s choice.
