OzHitch started with just the one 6 bolt hole pattern and has progressed to now having 3 different patterns.
The original 3500kg – 6 bolt hole coupling was the first and has the same pattern as the Vehicle Components hitches namely the AT35 All Terrain Coupling, Cruisemaster DO35, DO45, Hitchmaster, McHitch and Hitch-ezy hitches.
The new OzHitch 3.5 ton 4 hole hitch has the same bolt pattern as the Al-ko, Hyland and McHitch model hitches, although originally most Al-ko hitches were ball style… so again OzHitch can be retro fitted easily where these get removed.
There are many different ball hitch bolt hole patterns but only 3 main off-road hitch bolt patterns. The reason there are 3 different patterns is simple. Some hitch patterns go back many, many years and with the removal of ball, old style, worn out, or difficult to use hitches like the AT35 and fitment of new hitches like the OzHitch there is a need to be able to remove an old hitch and simply fit a new one without changing the hole centres currently in your trailer hitch plate… so for you the customer, the experience and satisfaction of fitting on a new hitch is easy to do by simply unbolting and bolting on the new OzHitch without fuss.
