32mm-22mm Tow Ball Reducer Bush

The 32mm-22mm Tow Ball Reducer Bush is made in Australia and designed to fit Couplemate 70mm receiver bars. This heavy-duty tow ball reducer changes the hole size to suit a smaller shank. This is ideal if you run a larger Tow Ball like our 70mm variant but which to change to a 50mm Standard tow ball without replacing your Reciever Arm.

We recommend retorquing the tow ball nut to the manufacturers specifications after inserting the

22mm or 7/8″ tow ball use a spring washer and nut, therefore in most cases, the nut and washer will not need to be replaced.
