KIBBLEWHITE Valve Guide - Big Twin 20-20HS

Valve guides are critical to engine longevity—they prevent excessive valve stem wear, maintain precise valve seating, and protect against catastrophic cylinder head damage. The KIBBLEWHITE 20-20HS is precision-engineered from nickel bronze to deliver superior durability in high-RPM Big Twin applications where stock guides fall short. If you're rebuilding a motor or restoring a vintage engine to reliable running condition, this is the guide specification you need.

The 5% nickel content provides exceptional wear resistance under demanding conditions, while the 80% copper base ensures heat is transferred away from the valve seat efficiently—critical for preventing guide galling and premature failure. KIBBLEWHITE's U.S.A. manufacturing means consistent tolerances and quality control you can trust. These guides accept no-lead fuel and work with any valve-stem material, giving you flexibility in your build choices.
