HKS Metal head gaskets are constructed from multiple layers of steel to ensure proper head to block sealing, even under the most severe conditions. The special metal used in the construction of the head gaskets is resistant to both heat and corrosion. All gaskets are coated with a special fluorine rubber coating to provide the ultimate sealing.
The HKS Stopper Type gasket is our most effective as it consists of the maximum layers of plates for the best possible seal. The better seal is due to a stopper ring around each combustion chamber.
