Kibblewhite Precision Bronze Intake Valve Guide (+.001in.) 20-2321

Guide Outside Diameter: .5660in. Guide Inside Diameter: .3085in.. We choose to use C630 nickel bronze as a material to make replacement 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.1957-1959 fits H-D XL 1958 fits H-D XLC 1958-1979 fits H-D XLCH 1972-1983 fits H-D XLH1000 1958-1971 fits H-D XLH900 1978-1983 fits H-D XLS Roadster 1977-1978 fits H-D XLT 1983 fits H-D XLX 1000
