KIBBLEWHITE Cast Iron Valve Seat 10-SC280

Valve seat recession is one of the fastest ways to lose compression and combustion efficiency in high-performance engines—especially when running aggressive fuel blends or boost. KIBBLEWHITE's Cast Iron Valve Seats use proprietary powdered metal technology to deliver exceptional hardness and thermal stability, preventing the microwelding and wear that destroy stock seats under extreme conditions. Whether you're running nitrous, methanol, or forced induction on the street or track, these seats maintain their integrity where budget alternatives fail.

Engineered for durability across leaded, unleaded, oxygenated fuels, and alternative blends, the 10-SC280 is purpose-built for serious racers and high-rpm street engines that demand reliability and longevity.
