Cometic cylinder base gaskets apply Multi-Layer Steel engineering to the seal point where an engine builder's tolerance decisions are tested first — the cylinder base joint on a Harley-Davidson Evo, Panhead, or Shovelhead, where combustion pressure, thermal expansion, and big bore modifications all meet. The range covers standard bore 1984 to 1999 Evolution Big Twin, plus two big bore variants: 3-13/16-inch and 3-5/8-inch displacement upgrades for the same Evo platform. The 1963 to 1965 Panhead and 1966 to 1984 Shovelhead are covered at standard bore, with a 3-5/8-inch big bore option for the older engine families as well. This kind of fitment specificity — standard versus big bore, Evo versus Shovelhead — is exactly what Cometic's motorsport-validated MLS construction is designed for. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Cometic through Iron Stable. Browse the full Cometic Cylinder Base Gaskets range below.
