Almanzar K series 9th gen chain cog. First of its kind. Harder then oem, stronger, the pin on the rear is not pushed in its one piece with the part. Our design is to ensure the pin doesn’t move causing engine failure. We also keyed it to ensure it never fails for years to come. Also this is not an oem modified part this is new metal not an oem part from Honda that was designed to make 200whp this was designed with power never imagined before by Honda engineers. Already track tested by many in the industry.
