Ballmounts - How to Measure
SELECTING THE RIGHT BALL MOUNT
For Safe, comfortable towing, the trailer should always be set up to tow on a level plane.
Sometimes a trailer's tongue is higher or lower than the ball mount on the vehicle, and a ball mount with a "rise" or a "drop" is required to level the trailer.
MEASURING FOR THE PROPER BALL MOUNT
1. Measure from the ground to the top of the hitch
2. Measure from the ground to the (inside) top of the trailer coupler, when level.
3. Subtract the height of the hitch ball (most are 2-1/2" - 3" high) from coupler measurement.
4. The difference in the two measurements is the amount of ball mount "rise" or "drop" required. In this example, an 8" drop is needed to make the trailer level.
