Like ball mounts, hitch balls are available in a number of weight capacities and sizes. Always
make sure the hitch ball selected has the proper
shank diameter and weight rating for the ball
mount as well as the coupler on your trailer. Using a 1

The diameter of the hitch ball shank must be matched to the ball mount hole diameter. The
shank should be no more than

” smaller than the hole.
To keep the hitch ball in top condition, a simple maintenance routine is recommended.
Coating it with light grease will minimize wear of both the coupler and hitch ball. Also, by
removing the hitch ball when not towing, or by protecting it with a special cover, you will help
prevent rust from forming on it.
TRAILER TONGUE
The tongue is the part of the trailer that extends forward to meet the tow vehicle, and it also
carries the coupler assembly. Knowledge of the trailer minimum and maximum tongue load
(conventional trailers) and king pin load (5th wheel and gooseneck trailers) is critical as it can
have a significant effect on the handling of the tow vehicle. Refer to your vehicle owner’s
manual to view the maximum conventional trailer tongue load listed for your vehicle, and
always maintain no less than a minimum of 10 to 15% of the total load.
SAFETY CHAINS/CABLES
Always use suitable safety chains/cables
between the tow vehicle and the trailer. If
the hitch should break or become
disengaged for some reason, these
chains/cables will provide an emergency
connection between the vehicle and the
trailer.
The chains/cables should be crossed
under the trailer tongue and attached to the
hitch or vehicle frame. Crossing the
chains/cables under the tongue will help
prevent the tongue from hitting the ground
should the trailer become disconnected.
Be sure to leave enough slack in the
chains/cables to turn corners without
binding; however, note that excessive slack
