Reproduction rear wheel dampers for the Honda CB500 and CB550 models listed. Includes 4 sets of Damper A and Damper B as shown in the picture. These are inserted into the hub and act as a cushion from vibration from the sprocket and chain on your bike. After 50 years its almost guaranteed that the rubber in these isolators is all but gone and probably loose. If you are changing out your sprocket this is a perfect time to replace these guys and have your bike riding comfy.
