70mm Tow Ball Tow Hitch Receiver, 4500kg

Australian Made by Couplemate Trailer PartsA tow bar receiver hitch kit is a set of components that allow you to attach your trailer or caravan to your tow vehicle.

Couplemate™ 70mm Tow Ball Tow Hitch Receivers are made from Solid Cast Iron. Because of their robust material, Genuine Couplemate™ trailer hitches guarantee a strong connection strength between your trailer and tow vehicle.

Over time, cast steel products are superior to fabricated/welded products. Welded ball mounts and hollow receivers can distort under off-road conditions and shock-loading events on the highway. When inverted, hollow hitches are at a greater risk of deforming.

It can also be used with the Cruisemaster DO45 tow pin for versatility.

You can trust the quality and durability of our 70mm receiver hitches, which are expertly cast, machined, and tested in Australia.

Towing Disaster: 4.5t on a 3.5t Receiver70mm Towbar Receiver

You can 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 right image shows a well-known heavy-duty tow ball mount or tow bar tongue rated at 3.5t.

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

Using equipment that is fit for purpose and rated at the appropriate weight limit is essential.

Therefore, we replaced the broken equipment with new equipment rated at 4.5t to ensure safety on the road.

The image on the right is a well-known heavy-duty tow ball mount or towbar tongue.
