Kibblewhite Valve Guide Kit
Kibblewhite Valve guides use copper based C63000 nickel-aluminum bronze as a material to make bronze valve guides because of its ideal characteristics for the application. The 5% nickel content provides superior resistance to wear, and the approximately 80 percent copper content delivers outstanding heat conductivity. KPMI® guide profiles are designed to have minimal effect on the airstream while maintaining critical cross sectional thickness in high temperature areas, which promotes high performance and endurance.
