COMETIC Gasket Kit - EVO/Big Twin C9130

Gasket failure on your EVO or Big Twin isn't just an inconvenience—it's catastrophic. Hot spots in the combustion chamber and uneven heat dissipation are the primary culprits behind blown gaskets and costly rebuilds. The COMETIC C9130 Gasket Kit eliminates these failure points with engineering designed specifically for Harley-Davidson's demanding power bands.

This complete top-end gasket set uses Extreme Sealing Technology (EST) to distribute combustion heat evenly across the gasket surface, preventing the localized stress that destroys inferior gasket materials. You get everything needed for a professional-grade rebuild—from cylinder base to rocker box—without chasing down individual components from multiple suppliers.
