Cometic C9467G EST Top End Gasket Kit

The Cometic C9467G is an EST (Extreme Sealing Technology) Top End Gasket Kit engineered for reliable, leak-free performance in demanding powersports and motorsports applications. Cometic's EST kits are built with embossed stainless steel head, base, and rocker gaskets coated with a proprietary rubber compound that draws heat away from the combustion ring and dissipates it evenly across the gasket surface, eliminating hot spots and reducing the risk of gasket failure.

Each kit contains all the gaskets, seals, and O-rings needed to fully rebuild the top end from the cylinder base upward — no sourcing individual components. Gasket materials include Multi-Layer Steel (MLS), rubber-coated steel, and aluminum foam where application-appropriate, ensuring an OEM-surpassing seal regardless of engine operating conditions. Valve stem seals and copper crush washers are included where applicable.

Key Features:

• EST (Extreme Sealing Technology) — embossed stainless steel gaskets with proprietary rubber coating for superior combustion sealing
