Product Details

The Cometic C7947 EST Top End Gasket Kit provides a complete sealing solution for rebuilding the top end of your engine from the cylinder base upward. Designed for 95mm (3.74") bore applications, this kit features Cometic's advanced Extreme Sealing Technology (EST) for superior durability and leak-free performance.

Key Features:

  • EST (Extreme Sealing Technology) with embossed stainless steel head, base, and rocker gaskets covered with proprietary rubber material
  • Multi-Layer Steel (MLS) construction with rubber-coated steel and aluminum foam materials for critical sealing surfaces
  • Head gasket material draws heat away from the combustion ring and dissipates it evenly to eliminate hot spots and prevent gasket failure
  • Complete kit includes all necessary gaskets, valve stem seals, copper crush washers, seals, and O-rings for a comprehensive top end rebuild
  • Non-asbestos materials impervious to fuels, coolants, and oils
  • Meets and exceeds OEM specifications for critical sealing and superior durability

Cometic gaskets are engineered with premium materials and advanced manufacturing processes to deliver the high-performance sealing solutions demanded by modern engines. Each component is precisely manufactured to ensure proper fitment and long-lasting reliability.
