James Gaskets Cylinder Base Gaskets

18 products — part of all Cylinder Base Gaskets

The cylinder base gasket seals the junction between barrel and crankcase on a Harley-Davidson engine — a joint that sees both combustion pressure and the thermal cycling that eventually degrades every original gasket. James Gaskets has supplied the Harley-Davidson restoration community for decades, and their cylinder base gasket range covers an exceptional span of Milwaukee history: VL flatheads from 1930 to 1936, Knucklehead engines from 1936 to 1947, K and KH flatheads from 1952 to 1956, Panhead powerplants from 1948 to 1965, and Shovelhead builds from 1963 to 1984. For restorers working on machines where correct materials and period-appropriate sealing surfaces are non-negotiable, James Gaskets provides the engineering confidence that comes from a manufacturer who understands these engines from the inside out. At Iron City Motorcycles in Leeds, our parts specialists can identify the correct James Gaskets cylinder base gasket for your specific engine year and displacement.
