S&S Cylinder Base Gaskets

6 products — part of all Cylinder Base Gaskets

S&S Cycle cylinder base gaskets are part of the precision ecosystem that makes an S&S big-bore engine build reliable over years of hard use. The cylinder base gasket seals between the cylinder barrel and the engine cases — a critical joint that must compress correctly and stay sealed through the thermal cycling of every ride. S&S produces their gaskets to match the bore dimensions and sealing face specifications of S&S cylinders, ensuring the correct crush and sealing area when torqued to specification. Using an S&S gasket in an S&S cylinder build removes the question of whether a third-party gasket will provide equivalent sealing — the dimensions are designed together rather than approximated. Harley-Davidson engine builds using S&S cylinders are common across Evolution and Twin Cam platforms, and keeping the gasket specification consistent with the cylinder specification is simply good practice.
