Tow Balls are manufactured in all sizes from 50mm to 3-inch.
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 at least 10 sec.
Tow balls are manufactured in various dimensions depending on the trailer loading, carrying capacity, D-Value and V-Value.

ADR Approved by Law is required for sizes over 3.5t, i.e. 70mm and 75mm tow balls.
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 Balls
Couplemate manufactured and tested various 50mm balls, including a high shoulder ball.
The highest shoulder we can produce using the most robust materials is 25mm.
Tow Bar Trailer 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 that many Chinese balls do not pass the Australian Standard, AS4177.2. Therefore, compliance standards are not met, and 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, call us on 07 33483822.
We also stock a tow ball collar for 10t couplings.
