Hitch ball

Choose a hitch ball of the proper size and weight rating for your trailer:

● The required hitch ball size is stamped on most trailer couplers. Most hitch balls also have the size printed on the top of the ball.

● Choose the proper class hitch ball based on the trailer weight.

● The diameter of the threaded shank of the hitch ball must be matched to the ball mount hole diameter. The hitch ball shank should be no more than 1/16” smaller than the hole in the ball mount.

● The threaded shank of the hitch ball must be long enough to be properly secured to the ball mount. There should be at least 2 threads showing beyond the lock washer and nut.
