Drag clicker for overseas-made Abu Ambassador reels, usable for both left and right-hand handles. I use it on my 5500c3 and 4600c Gunner. Both could be installed without modification. (Install as shown in the first photo. If you feel any discomfort during installation, try using the original parts instead of the upper retaining part in the ninth photo.) It should fit C3, C4, Gunner, Rocket, and IMAE models, etc., if they have the same size and shape gears, but please check the shape and size of your gears before purchasing. (Size is indicated in the 6th to 9th images.) According to information from customers who have purchased, it can also be installed on the 6500C high-speed winch. There are two clicker parts included, but the part with the bent claw is for the right-hand handle. If you are using a left-hand handle, please bend the clicker part without the bend in the opposite direction for use. In my personal opinion, the sound is surprisingly loud and clear, and the volume doesn't decrease much even when tightening the drag. Of course, the drag function also works fine. We are not responsible for any failures that may occur during part replacement, so please do so at your own risk. (The main gear and shaft in the first photo are not included.) Additional information: Photos have been added to the 10th to 15th images. These are the main gears of my 4600C Gunner. I hope this is helpful.
