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 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.
