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.
Ball Mount Measurements
Distance from the center of the ball hole to the center of the pin hole
Distance from the top of the shank to the top of the ball platform
Distance from the top of the shank to the top of the ball platform
Measuring For the Proper Ball Mount
Measure from the ground to the
top of the hitch.
Measure from the ground to the
(inside) top of the trailercoupler,
when level.
Subtract the height of the hitch ball (most are 2½" - 3" high) from coupler measurement.
An 8" drop is needed to make the trailer level.
THE DIFFERENCE IN THE TWO MEASUREMENTS IS THE AMOUNT OF
BALL MOUNT "RISE" OR "DROP" REQUIRED.
