About This Product
When refreshing the heads on an Evolution or Twin Cam motor, these U.S.A.-made cast iron valve seats from Kibblewhite are a reliable choice. This seat features a 44.62mm outside diameter and a 35.00mm inside diameter, making it a perfect replacement for the exhaust side on 1984 to 2017 Big Twins, excluding 110-inch and Milwaukee-Eight models. It also fits 1987 Sportster 1100, 1988 to 2022 Sportster 1200, and 2008 to 2012 XR1200 models, as well as 2006 Buells. These seats offer excellent thermal transfer and resist micro-welding under high heat. They are sold individually and serve as a high-quality alternative to OEM part number 18011-86, suitable for use with all modern fuel blends.
Manufacturer part number: 10-SC446.
