OEM dampers are made in China or India for all the engine manfactures. When I replaced mine the only thing available was OEM from China for the ISX. Pittsburgh Power encouraged the only U.S. manfacture of dampers to build the model for the ISX. Many things from China are cheaply designed and built, and quality control is questionable. Vibratech makes the damper that Pittsburgh Power will sell for the same or lower price than the manfacture.
