S&S Gaskets & Seals

79 products — Page 2 of 2

S&S gaskets and seals are engineered specifically for S&S performance builds, addressing the sealing demands that standard OEM gaskets were not designed to meet. When you bore out a Harley-Davidson Big Twin cylinder to S&S 96ci, 107ci or 124ci specifications, or fit S&S heads to a Milwaukee-Eight, the head gasket has to seal against cylinder pressures and temperatures that a stock bore configuration never produces — and S&S application-specific gaskets are made to those tolerances. That coordination between S&S engine components and S&S gaskets is what separates a leak-free performance build from one that requires a top-end retorque after a few hundred miles. S&S produces complete gasket kits for their cylinder and engine packages covering Harley-Davidson Evolution, Twin Cam and Milwaukee-Eight platforms, with MLS head gasket options for high-compression applications where multi-layer steel construction provides the crush resistance that composite gaskets cannot match. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks S&S gaskets alongside the full S&S engine components range. Browse the full S&S Gaskets & Seals range below.
