Cometic Gasket Sets Top End

35 products — part of all Gasket Sets Top End

Cometic top-end gasket sets bring Multi-Layer Steel technology to Harley-Davidson engine rebuilds — precision-embossed stainless layers that seal under the cylinder pressures and temperature cycles a built Twin Cam or Evolution engine generates, rather than the conservative operating conditions a standard replacement was designed around. The fitment covers 1999 to 2017 Twin Cam in 88, 95, 96, and 103-inch configurations (excluding Twin Cooled), the 1991 to 2003 and 2004 to 2006 XL1200 Sportster, and the 1984 to 1991 Evolution Big Twin. Twin Cooled is correctly excluded — those heads require a different gasket design, and Cometic lists them separately. The MLS construction was validated in professional motorsport before Cometic applied it to street engines; the sealing reliability that matters on a circuit is the same property that counts on a high-compression Harley-Davidson street build. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Cometic through Iron Stable. Browse the full Cometic Gasket Sets Top End range below.
