Tow Balls are manufactured in all sizes from 50mm to 3″.

Tow Balls are designed and manufactured to connect different weight trailers to the tow vehicle. What is the most common tow ball size in Australia? The answer is 50mm.

The Australian Standard is AS 4177.2—2004. Publishing this standard is forbidden; however, the maximum force applied is 85kN for no less than 10 sec.

Tow balls are manufactured in various sizes depending on lo loading, carrying capacity, D-Value and V-Value.

ADR Approved by Law is required for sizes over 3.5t, i.e. 70mm and 75mm.

As a result of growing demand, Couplemate commenced the manufacture of all ball sizes. Our largest truck ball size is 3″ for our 10t gooseneck coupling.

High Rise Tow Balls

Couplemate manufactured and tested a large variety of 50mm balls including a 50mm shoulder ball.

The highest shoulder we are able to produce using the strongest of materials is 25mm.

Tow Bar Hitch

We recommend offroad couplings of all brands use a solid cast receiver hitch or tow ball hitch. Hollow receivers have a welded tongue that distorts in extreme offroad conditions and under shock loading events on the highway.

We also found many Chinese balls do not pass the Australian Standard, AS4177.2. Therefore, compliance standards are not met; thus, strict penalties and loss of reputation for offending companies are costly.

Further, to ensure compliance with the regulations, Couplemate manufacturers and tests its towing equipment.

Finally, if you need us to manufacture custom towing appliances, give us a call on 07 33483822. We also stock a tow ball collar for 10t couplings.
