To check if a tow ball mount will fit your vehicle you need to check the following:
Receiver Size
In almost all cases the receiver will be around 51mm / 2" square. In some cases usually with imported US vehicles the receiver maybe 2.5" or sometimes 3" square. We do sell a reducer for 2.5" to 2" HERE.
Sometimes there will be some movement as there will be a few millimetres in difference - we recommend using Anti Rattle Shims to sort if it is an issue.
Receiver Length
There are 2 measurments you need to check on the vehicle receiver as follows:
Measurement A - Pin to End of receiver. Measure from the centre of the lock pin hole to the end of the receiver (where you insert the towball mount)
Measurement B - Pin to the rear of the receiver. Measure from the centre of the lock pin hole as far into the receiver as you can go.
When choosing a towball mount (most of our mounts have dimensions on the listing) the mount needs to have an A measurement longer than the vehicle receiver and a B measurment shorter than than the vehicle receiver to fit.
Lock Pin Size
Lock pins are 16mm standard size.
