Trailer Hitch Balls

Ball Dimensions

A trailer hitch ball is the towing component that attaches to the ball mount and provides an attachment point for the trailer coupler. The trailer coupler sits on top of the ball and is locked into place. The ball allows the trailer to pivot to provide smooth turning while towing. Trailer hitch balls are sold in various shank lengths and diameters, ball diameters and weight capacities to meet your towing needs.


NOTE: Ball torque depends on the shank diameter





The Two Items Needed When Choosing a Hitch Ball


1.Trailer Coupler

Three Ball DiametersTrailer and Coupler

Look at the trailer coupler. It will indicate what size ball diameter you need and the weight capacity of the trailer. The weight rating of the hitch ball should be equal to or greater than the weight rating of your trailer, hitch and ball mount.


Three ball diameters sizes are available: 1-7/8", 2" and 2-5/16". The 1-7/8" balls are typically used on smaller trailers and have a weight capacity of 2,000 lbs. The 2" balls are used on medium sized trailers and have a weight capacity of up to 8,000 lbs. The 2-5/16" balls are used for heavy duty trailers and have a weight capacity of up to 30,000 lbs.


2.Ball Mount

Different Ball Shank LengthsBall Mount Sizes

The ball mount determines the ball shank diameter and ball shank length. Three shank diameter sizes are available: 3/4", 1" and 1-1/4". The 3/4" diameter shank is used on 1-1/4" X 1-1/4" Class I and Class II hitches. The 1" diameter shank is used on Class III and Class IV hitches. The 1-1/4" diameter shank is used on Class IV, Class V and weight distributing hitches.


Balls are available with shank lengths of short (less than 2"), medium (between 2" and 3") and long (greater than 3"). The drawbar thickness determines what shank length is needed. At least one thread needs to be visible beneath the lock washer and nut once the ball is screwed into place.
