KIBBLEWHITE Valve Seat 10-HC445

If you're running titanium valves in a high-performance engine, valve seat material matters more than most builders realize. The KIBBLEWHITE 10-HC445 is a copper-based seat engineered specifically to handle the thermal and mechanical demands of titanium valves, delivering superior wear resistance and thermal conductivity where generic seats fail. Two years of R&D testing across single and multi-cylinder platforms—from street bikes to full-race engines—proves these seats outperform industry standards in every measurable way.

Whether you're building a British 4-stroke, European platform, or cutting-edge race engine, these seats are trusted by successful builders worldwide because they simply work harder and last longer.
