Valve Seat

Copper-based material designed specifically for use with titanium valves in high performance applications; Give the seat excellent thermal characteristics as well as resistance to corrosion and wear; These seats are the result of a two year KPMI R&D effort during which we recorded and verified results with 4- and 5-valve singles, multi-cylinder street bikes, and British and European 4-strokes; In each test the wear, thermal conductivity and machinability surpassed the standards we set for success; These seats are used by successful builders around the world in all forms of racing; Made in the U.S.A.
