This V-Twin Top End Gasket Kit uses EST (Extreme Sealing Technology) to deliver reliable sealing for high-performance engines. 🔧

  • EST gasket kit includes embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material.
  • Head gasket material draws heat away from the combustion ring and dissipates it evenly across the gasket surface to eliminate hot spots and gasket failure.
  • The set contains all the necessary gaskets, seals, and O-rings to rebuild the top end from the cylinder base upward.
  • Made in the USA. 🇺🇸

Each kit is engineered for consistent torque retention and long-term durability, helping maintain proper compression and prevent leaks.
