Identify the Drop or Rise required.

To choose the correct drop or rise for your hitch mount please follow the below steps and refer to the diagram and video.

1. On level ground, measure the distance from the ground to the top inside of the Hitch Receiver (A - refer diagram)
2. Level your trailer using your jockey wheel to adjust the height.
3. Measure the distance from the ground to the underside of the Trailer Coupling (B)
4. A-B = Drop or Rise required (C). If it is a negative number then you will require a rise
