Cometic Top End Gasket Kit with Extreme Sealing Technology

The Cometic Top End Gasket Kit with Extreme Sealing Technology (EST) is made to rebuild an engine's top end, from the cylinder base upward. It is a top end gasket set for motorcycle, ATV and powersports engines. Cometic builds these kits in the USA.

Key Features:

• EST construction: embossed stainless steel head, base and rocker gaskets covered with a proprietary rubber material for dependable sealing
• Even heat dissipation: the head gasket material draws heat away from the combustion ring and spreads it across the gasket surface. This helps prevent hot spots and gasket failure.
• Complete top end rebuild: kits include the gaskets, seals and O-rings needed to rebuild the top end
• Multi-layer steel (MLS) head gaskets: on applicable kits, these help spread torque load evenly across the sealing surface. This reduces bore distortion and supports better piston ring seal.
• Made in the USA

Cometic uses different gasket materials in each kit, chosen for the sealing job at each location. The result is a leak-free seal for a refreshed or performance-built engine. Each kit part number is engineered for its specific engine application.
