James Gaskets Gasket Sets Top End

36 products — part of all Gasket Sets Top End

James Gaskets top-end gasket sets are built on 45 years of exclusively Harley-Davidson manufacturing — the head gasket material stack for a 1999 to 2004 Twin Cam 88-inch engine is a different specification to the 2005 to 2017 95 and 103-inch Twin Cam, and both differ again from the 1984 to 1991 Evolution Big Twin or the 1966 to 1984 Shovelhead. James Gaskets doesn't guess at this — the compound and thickness are worked out for each engine's bore, head surface finish, and operating temperature range. The Twin Cooled exclusion on the Twin Cam kits is correctly listed: those engines run different cylinder head geometry and a standard top-end kit won't seal them. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks James Gaskets through Iron Stable because 45 years of single-brand Harley-Davidson focus produces this level of application precision. For a proper top-end rebuild on a Harley-Davidson, the gasket set engineered for that specific engine is the right choice. Browse the full James Gaskets Gasket Sets Top End range below.
