Cometic Valve Guides Gaskets And Seals

4 products — part of all Valve Guides Gaskets And Seals

Cometic valve guides, gaskets, and seals bring Multi-Layer Steel engineering to Harley-Davidson engine work that the generic aftermarket simply doesn't offer — precision-embossed stainless steel layers that seal reliably under extreme cylinder pressures, validated in professional motorsport before reaching the street. The fitment range runs deep: late Shovelhead engines from 1981 to 1984, Knucklehead applications from 1936 to 1947, Big Twin and Flathead configurations from 1948 to 1979, and Twin Cam including Sportster XL through 2022 and XR1200. This is not one-size-fits-best engineering; the MLS gasket technology is calibrated for each engine family's specific bore, port geometry, and thermal characteristics. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Cometic through Iron Stable because the quality benchmark matters when you're pulling the top end off a Harley-Davidson. If you're doing serious engine work — a performance build, a high-mileage rebuild, or a period restoration — Cometic is the starting point that professional shops reach for.
