S&S Gaskets Cylinder Head

8 products — part of all Gaskets Cylinder Head

S&S cylinder head gaskets are engineered to seal the engines that S&S themselves build, which gives them an authority in this category that few other brands can claim — the company has been manufacturing complete V-twin engines in Viola, Wisconsin since 1958, and their gasket range reflects that depth of engine knowledge. The S&S selection spans Shovelhead Harley-Davidson engines from 1966 to 1984, including the brand's own SH and Panhead-series replacement engines, through to the SSW+ Super Sidewinder Plus engines based on the Evolution Big Twin and Twin Cam architecture, and extends to modern 2017–2025 Softail and FLT Touring platforms. That breadth means S&S head gaskets are the right call whether you are rebuilding a period-correct Shovelhead at standard bore, running a 3-5/8-inch big bore conversion, or refreshing a more recent Milwaukee-Eight-era Harley-Davidson. S&S specifies correct bore diameter and material for each application, removing the guesswork on a critical sealing surface where an inferior gasket risks compression loss and coolant or oil ingestion. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks S&S gaskets alongside the wider S&S engine components range. Browse the full S&S Gaskets Cylinder Head range below.
