EST (Extreme Sealing Technology) gasket kit includes embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material for superior sealing and resistance to leakage. 🔧

The head gasket material is engineered to draw heat away from the combustion ring and dissipate it evenly across the gasket surface to eliminate hot spots and reduce gasket failure. This set contains all necessary gaskets, seals, and O-rings to rebuild the top end from the cylinder base upward.

Made in the USA.
