We choose to use C630 nickel bronze as a material to make valve guides because of its ideal characteristics for the application. The 5 percent nickel content provides superior resistance to wear, and the 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. Precision-machined guides
Manganese bronze guide material is softer than nickel aluminum bronze valve guides
Excellent heat conductivity which promotes long valve life
Guides can be easily reamed with a battery-operated or electric drill and finished with a high-quality ball hone
Eliminates the need for expensive honing equipment that would be required for nickel bronze valve guides
Machined to accept OEM and aftermarket seals
Made in the U.S.A.
