Cometic Top End Gasket Kit for KTM, Husqvarna and GasGas 95 mm 4-Stroke Engines (C3604-EST)

The Cometic C3604-EST Top End Gasket Kit is designed for reliable top-end service on compatible KTM, Husqvarna, and GasGas 4-stroke engines. This comprehensive kit includes the correct base gasket, head gasket, cylinder O-rings, and other top-end-specific O-rings or seals required for removal and installation. It provides the components needed to restore dependable sealing during top-end rebuilding and maintenance.
The MLS head gasket uses a multi-layered steel construction to promote even torque distribution across the gasket sealing surface. This helps reduce bore distortion and support improved piston ring sealing for consistent engine performance. The head gasket is engineered for today’s high-output 4-stroke naturally aspirated and boosted machines, helping withstand the high cylinder pressures and temperatures produced by high-horsepower engines.
Cometic’s EST, or Extreme Sealing Technology, construction features embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material. The outer layers of the MLS head gasket are embossed and coated with Viton rubber for dependable sealing around critical engine surfaces. The gasket material also helps draw heat away from the combustion ring and dissipate it evenly across the gasket surface, reducing hot spots and the risk of gasket failure. The Cometic C3604-EST kit is made in the USA and offers a practical sealing solution for compatible 95 mm 4-stroke applications.
