Cometic Gasket Sets Primary

31 products — part of all Gasket Sets Primary

Cometic primary gasket sets for Harley-Davidson are complete sealing packages for primary chaincase service — every gasket, O-ring, and seal required to reseal the primary in a single purchase rather than sourcing each piece separately. Cometic's primary kits use the same precision-compound approach as their head gasket range: each sealing element is specified for the surface finish, clamping pressure, and thermal cycling of the primary chaincase rather than being a generic material cut to shape. The range covers Evolution Big Twin, Twin Cam, and Sportster primary designs, with Big Twin options spanning models from the early 1970s to the Milwaukee-Eight era. Iron City Motorcycles stocks Cometic primary gasket sets for the mechanic who understands that Harley-Davidson primary work done properly means clean, dry, and not needing to revisit.
