Description

The Cometic Gasket C3779-EST is a top-end gasket kit designed for off-road applications. It includes the necessary base, head gasket, and cylinder O-rings, along with other specific O-rings or seals required for top-end removal and reinstallation.

These 4-stroke head gaskets utilize a multi-layered steel design with an embossed and Viton rubber-coated outer layer, built to withstand the demands of high-horsepower, high-cylinder-pressure engines. This gasket kit is made in the USA.
