Tow Bar Hitch Extensions Australia — What You Need to Know

A steel bar that slides into your towbar receiver and extends the tow point rearwards. Used to clear a 4WD's spare wheel, a swung-out rear door, or to push a bike carrier further back.

50mm is the Australian standard. 2-inch (50.8mm) is found on some US imports. Common extension lengths are 200mm, 300mm and 400mm. Anything over 400mm requires special engineering certification.

Adding length reduces towing capacity. A 300mm extension typically halves rated capacity. Always check the extension's stamped rating against your trailer's loaded weight.

Legal provided you don't exceed the extension's rated capacity, the extension is properly secured with a pin and clip, and the trailer's number plate and lights remain visible.

Hayman Reese, TAG and ARK make heavy-duty Australian-made hitch extensions. Avoid no-brand imports — the steel quality and welds are not always to AS spec.
