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 reducer reduces the hole size from 70 mm to 50 mm. Remove the 70mm tow ball and install a 50mm tow ball for towing small trailers.
This is ideal if you run a larger tow ball, like our 70mm variant, but want to switch to a 50mm standard tow ball without replacing your receiver arm.
Specifications
- Outside Diameter: 32mm
- Inside Diameter: 22.62mm
- Height: 24mm
We recommend retorquing the tow ball nut to the manufacturer’s specifications after inserting the tow ball reducer.
22mm or 7/8″ tow ball uses a spring washer and nut; therefore, in most cases, the nut and washer will not need to be replaced.
Please note: the sizes above are descriptive only—view specifications for exact dimensions.
If the nut is a Nylock, we recommend installing a spring washer beneath it.

Product FAQ & Safety Guide
The 22mm – 32mm Reducer Bush allows you to safely adapt a 50mm tow ball into a heavy-duty 70mm tow ball mount. Please follow these critical guidelines to ensure safe towing.
What You SHOULD Do
- Use a matching washer: Always use a high-tensile spring washer beneath the nut to spread clamp force evenly.
- Torque correctly: Tighten the tow ball nut to the manufacturer’s recommended specification using a proper spanner or socket.
- Inspect regularly: Frequently check the assembly for any signs of loosening, wear, or corrosion, especially after long trips.
- Verify compatibility: Ensure you are using it specifically with heavy-duty drop-forged tow ball mounts.
What You Should NOT Do
- Don’t panic if it’s loose initially: The bush is not designed to hold itself in the mount without the tow ball installed. It locks tight once the nut is clamped.
- Don’t exceed load ratings: Never exceed the maximum towing capacity of the lower-rated component (the 50mm ball or the bush).
- Don’t weld the bush: Do not tack-weld or permanently modify the reducer bush to the tow bar tongue.
- Don’t reuse damaged hardware: If the bush or tow ball thread becomes deformed or heavily rusted, replace them immediately.
