Complete top-end gasket kit engineered to deliver reliable sealing and long service life. EST (Extreme Sealing Technology) provides embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material to improve durability and sealing performance.

  • Head gasket material draws heat away from the combustion ring and dissipates it evenly across the gasket surface to eliminate hot spots and reduce the risk of gasket failure.
  • The set contains all necessary gaskets, seals, and O-rings to rebuild the top end from the cylinder base upward, simplifying installation and parts sourcing.
  • Manufactured to high standards and made in the USA. 🔧🇺🇸
