This Arctic Cat cylinder head gasket, OEM part numbers 0691-055 and 11141-88C00, is a direct replacement gasket that sits between the cylinder head and engine block to seal the combustion chamber and keep coolant and oil passages separate. It’s designed for Arctic Cat powerplants that specify these exact part numbers, ensuring precise fitment with the mating surfaces and gasket recesses used by Arctic Cat service literature. As an OEM component, it provides the essential sealing integrity needed to maintain engine compression and proper cooling lubrication, helping prevent leaks and head-gasket failures in routine maintenance or repair.
