Description

Cometic StreetPro Kits are designed for budget-minded street-rodders looking for all necessary gaskets and seals for a top-end rebuild. The kits include quality gasket materials such as MLS, AFM, Aramid Fiber, and Armor Clad. These head gaskets sit between the engine block and cylinder head, preventing the mixture of gasses and oils with the cooling system. All Cometic products are made in the United States with American-manufactured materials. Cometic Gasket has expanded from the powersports industry to service Domestic Automotive, Sport Compact, V-twin, Marine, Diesel, Agricultural, Industrial, and Stationary Power markets.
