What size Ball Mount do I need?
Step 1:
Measure from the ground to the top of the hitch. |
 |
|
Step 2:
Level trailer, then measure from the ground to the top of the trailer coupler.
|
 |
|
Step 3:
Subtract the height of the hitch ball (most are 2-1/2" to 3" high) from Step 2. The example would be 18" minus 3" = 15".
|
|
Step 4:
The difference between Step 1 and Step 3 would be the "Drop" or "Rise" that is needed for your Towing System. The example would be a result of 8" (23" minus 15") Drop is required. If you do not have a trailer to measure with standard ball height is 15" to base of ball mount or 18" to the top of the ball.
