10-SC410 KPMI, cast iron valve seat. 41mm OD

Kibblewhite Precision Machining offers these U.S.A.-made cast iron valve seats for custom engine builders and specialized applications. These seats are compatible with all modern fuels, including leaded, unleaded, and high-ethanol blends. This specific seat has a 41mm outside diameter and a 31mm inside diameter, with a height of 11mm. Because the material is consistent across the Kibblewhite line, these are suitable for both intake and exhaust positions. They offer excellent thermal conductivity and are highly resistant to micro-welding, which is vital for maintaining valve seal integrity over time. A leading edge is included to assist with the installation process. These universal seats are sold individually and are perfect for custom machining projects where standard sizes won't work.
