Towing Disaster: 4.5t on a 3.5t Receiver

You are able to use a Tow Ball Reducer Bush to take a 4.5t receiver to a 3.t receiver. However, you cannot go the opposite way.

The image on the right shows a well-known heavy-duty tow ball mount or tow bar tongue that is rated to 3.5t.

However, a welder has used an oxy torch to enlarge the hole size to 32mm to fit a 4.5t tow ball.

It is important to use equipment that is fit for purpose and rated at the appropriate weight limit. Therefore, we replaced the broken equipment with new equipment rated at 4.5t to ensure safety on the road.
