The EST (Extreme Sealing Technology) gasket kit includes embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material to provide durable, long‑lasting sealing performance. 🔧

Head gasket construction 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.

This kit is manufactured in the USA and is engineered for reliable installation and service life across demanding operating conditions. 🇺🇸
