COMETIC Top End Gasket Kit — 0.81 mm, 4-Stroke – 36-85 Big Twin, 79-80, 84 Touring, 85 Softail, 52-56 Model K, 57-80, 82-83, 85 Sportster

Top end gasket kit includes the correct base and head gaskets, cylinder O-rings and additional top-end seals required for removal and reinstallation of the top end. 🔧

Multi-layer steel (MLS) head gaskets promote an even torque load across the sealing surface, reducing bore distortion and improving piston ring seal for more power. ⚙️

Designed for high-output 4-stroke engines, these head gaskets feature embossed outer layers coated with a Viton rubber material to meet the demands of modern, high-cylinder-pressure machines.

EST (Extreme Sealing Technology) variants include embossed stainless steel head, base and rocker gaskets covered with a proprietary rubber material for enhanced sealing and heat dissipation.

The gasket construction draws heat away from the combustion ring and dissipates it evenly across the gasket surface to reduce hot spots and the risk of gasket failure.

Made in the USA.
