Follow the simple steps illustrated below to determine the ball mount with enough rise or drop to keep the trailer in a level position.

To Measure Ball Mount Rise:

A-B=C

A = distance from ground to bottom of trailer coupler

B = distance from ground to top I.D. of the receiver tube opening

C = amount of rise necessary to keep trailer level

To Measure Ball Mount Drop:

B-A=C

A = distance from ground to bottom of trailer coupler

B = distance from ground to top I.D. of the receiver tube opening

C = amount of drop necessary to keep trailer level
