COMETIC Top End Gasket Kit - KTM/Husqvarna C3808

A failing head gasket means catastrophic engine damage and downtime you can't afford. The COMETIC C3808 top end gasket kit delivers the sealing integrity and thermal stability required to handle today's high-output 4-stroke engines—whether naturally aspirated or boosted. This complete kit eliminates guesswork during top-end R&R by including every gasket and seal you need in one box.

COMETIC's multi-layered steel construction with embossed stainless steel and Viton rubber coating distributes clamping load evenly across the sealing surface, minimizing bore distortion and maximizing piston ring seal. The proprietary Extreme Sealing Technology (EST) actively draws heat away from the combustion ring, preventing hot spots and premature failure—critical when running high cylinder pressures.
