COMETIC C7877-EST Top End Gasket Kit for Honda Engines - 94mm

Top End EST Gasket Kit - 94 mm - Honda

The COMETIC C7877-EST Top End Gasket Kit is designed for high-performance Honda engines with 94mm bore size, including various models of Honda motorcycles and ATV units. This comprehensive kit includes a precision-engineered MLS head gasket, base gasket, and cylinder O-rings, ensuring a complete top-end rebuild. The kit also features additional top-end specific O-rings and seals necessary for reliable removal and installation, making it an ideal choice for performance enthusiasts and professional rebuilds.
Constructed with multi-layered steel, the MLS head gaskets in this kit provide an even torque load across the sealing surface, reducing bore distortion and enhancing piston ring seal integrity. This design promotes increased power output and improved engine longevity, especially in high-horsepower, high-cylinder-pressure applications. The embossed outer layers coated with Viton rubber improve sealing performance and resistance to heat and pressure, making these gaskets suitable for both naturally aspirated and boosted 4-stroke engines.
The EST (Extreme Sealing Technology) gaskets feature embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material. This innovative material helps draw heat away from the combustion ring and dissipate it evenly across the gasket surface, effectively eliminating hot spots that could lead to gasket failure. These features ensure a durable, reliable seal under demanding conditions, whether on high-performance racing engines or heavy-duty applications.
Manufactured in the USA, the COMETIC C7877-EST gasket kit is tailored to meet the rigorous demands of today's high-horsepower engines, offering a combination of advanced materials and precision engineering. It is compatible with Honda models including CRF450R, CRF450X, CRF250R, CRF250X, and other Honda 4-stroke engines with 94mm bore size, providing a trusted solution for top-end rebuilds and performance enhancements.
