The Cometic C7826-EST Top End Gasket Kit is designed for Honda performance and service applications requiring reliable sealing and optimized engine operation. This kit features an 89 mm bore gasket configuration and is engineered to raise compression for improved low-end power. Cometic gasket materials provide dependable sealing performance while supporting proper torque retention during repeated heat cycles and demanding riding conditions.
The kit combines graphite, fiber, and O-ring gasket technologies. Graphite gaskets use a steel core laminated on both sides with flexible graphite for strength, conformability, and sealing reliability. Fiber gaskets are designed for maximum seal, flexibility, and torque retention, while the O-ring gaskets meet or exceed OEM specifications. This combination helps support consistent top-end sealing during engine assembly or rebuild work.
