Cometic Gaskets Cylinder Head

51 products — part of all Gaskets Cylinder Head

Cometic cylinder head gaskets for Harley-Davidson are built on the same Multi-Layer Steel technology that the brand developed for professional motorsport, using precision-embossed stainless steel layers to maintain a reliable seal across the combustion pressures and thermal cycling that high-performance Harley-Davidson engines generate. The range addresses the most demanding engine combinations in the V-twin market: 1999-2017 Twin Cam engines with 3-7/8 inch bore 95 and 103 cubic inch configurations, 2014-2016 FLT Touring Twin Cooled 103 engines, classic 1984-1999 Evo Big Twin and XL Sportster 1200 platforms, and specialist applications including TP Engineering 4-1/8 inch big bore Evo cylinders. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, recommends Cometic for performance rebuilds and big bore conversions where a standard composite head gasket would be the weakest link in the engine. When cylinder pressures rise beyond stock — whether through cam upgrades, compression increases, or a Milwaukee-Eight build — the MLS construction ensures the head gasket is not the limiting factor in a Harley-Davidson engine's long-term reliability.
