Cometic Gaskets & Seals

519 products — Page 5 of 11

Cometic gaskets bring motorsport-derived sealing technology to Harley-Davidson engine builds, filling the space between standard OEM replacement gaskets and the demands of performance-oriented rebuilds. Their Multi-Layer Steel head gaskets — multiple precision-embossed layers of stainless steel that conform under torque and maintain a reliable seal under sustained high cylinder pressures — represent a different approach to sealing than fibre or composite gaskets used in standard replacement applications. For Evolution Big Twin builds running higher compression, Twin Cam engines breathing through performance cams and air cleaners, or Milwaukee-Eight motors pushed beyond stock output, Cometic's sealing technology handles elevated thermal and mechanical loads that standard gaskets may not. Complete top-end and full engine gasket kits simplify ordering for Sportster XL, Evolution, and Twin Cam rebuilds with everything in a single set. Cometic also produces primary and transmission gaskets in chemically blown compounds and reinforced constructions for high-temperature applications throughout the drivetrain. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Cometic gaskets for UK builders taking their Harley-Davidson engines beyond standard specification.
