Activator Replacement Spring for Chiropractic Adjustment This is one replacement spring for the Activator. Please use it as a spare or for repair. We have actually replaced the springs in images II and IV to confirm they work. ※This is not the main body of the Activator. For reference, the short spring in the third image is the broken one, and the long one is the item for sale. It can be installed directly. Quantities are limited, and price reductions are not possible. ※Please make sure you can remove the spring from your Activator before purchasing.
