We talked recently about Trailer Hitch Ball Sizes.  The next step is to talk a bit about the part the hitch ball mounts to which is the Trailer Hitch Ball Mount.

The ball mount is the component that inserts into the hitch. 

First and foremost, make sure that the ball mount you buy is rated equal to or higher than the hitch class you have mounted. The end goal is to make sure that when your trailer coupler sits on top of the hitch ball in the ball mount that the trailer is level. Sometimes the trailer sits higher or lower than the ball mount. In those cases a ball mount with a rise or drop is used. 

Here’s a way to figure out what kind of ball mount you need. Measure the distance from the ground to the top of the hitch and add (2 ½ - 3”) for the height of the hitch ball. Then measure from the ground up to the top of the (leveled) trailer coupler. Use the ball mount with a rise, drop or straight as needed so that the trailer remains level. To get the ball mount that meets your needs here’s a guide to correct measuring.

What to Measure for Class I & Class II



  • A: Length = The distance from the center of the ball hole to the center of the pin hole.
  • B: Height = The distance from the top of the shank to the top of the ball platform.
  • C: Drop = The distance from the top of the shank to the top of the ball platform.

What to Measure for Class III, Class IV & Class V



  • A: Length = The distance from the center of the ball hole to the center of the pin hole.
  • B: Height = The distance from the top of the shank to the top of the ball platform.
  • C: Drop = The distance from the top of the shank to the top of the ball platform.
 
Ball Mounts are available in a variety of designs for different uses. The most common are:

Standard: Fixed length and rise or drop.
 
Self Aligning: This style has an integrated aligning system  used to guide the trailer coupler to the ball
 
Multi-Use: This style incorporates 2 or more different ball sizes into one ball mount so you can use the same mount for a variety of coupler sizes
 
Cushioned Ball Mounts: Integrated cushion feature provides a smoother ride by preventing jolts and jerking.
