WARNING
Trailer hitch components have specific
weight ratings. Your vehicle may be ca-
pable of towing a trailer heavier than the
weight rating of the hitch components.
Never exceed the weight rating of the
hitch components. Doing so can cause
serious personal injury or property
damage.
Hitch ball
Choose ahitch ball ofthe proper sizeand 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 theproper classhitch ballbased on
the trailer weight.
The diameter of the threaded shank of the
hitch ballmust be matchedto 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 threadedshank of thehitch ball mustbe
long enough to be properly secured to the
ball mount. There should be at least 2
threads showing beyond the lock washer
and nut.
Ball mount
The hitch ball is attached to the ball mount and
the ball mount is inserted into the hitch receiver.
Choose a proper class ball mount based on the
trailer weight. Additionally, the ball mount should
bechosento keepthetrailer tonguelevelwiththe
ground.
Weight carrying hitches
A weight carrying or “dead weight” ball mount is
one thatis designedto carrythe wholeamount of
tongue weight and gross weight directly on the
ball mount and on the receiver.
Weight distribution hitch
This type of hitch is also called a “load-leveling” or
“equalizing” hitch. A set of bars attach to the ball
mount and to the trailer to distribute the tongue
weight (hitch weight) of your trailer. Many vehicles
can’t carry the full tongue weight of a given trailer,
and need some of the tongue weight transferred
through the frame and pushing down on the front
wheels. This gives stability to the tow vehicle.
A weight-distributing hitch system (Class IV) is
recommended if you plan to tow trailers with a
maximum weight over 5,000 lbs. Check with the
trailer and towing equipment manufacturers to
determineifthey recommendtheuse ofaweight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may af-
fect the operation of trailer surge brakes. If
you are considering use of a weight-
distributing hitch system with a surge
brake-equipped trailer, check with the
surge brake, hitch or trailer manufacturer
to determine if and how this can be done.
Follow the instructions providedby the manufac-
turer for installing and using the weight-
distributing hitch system.
General set-up instructions are as follows:
1. Park unloaded vehicle on a level surface.
With the ignition on and the doors closed,
allowthe vehicleto standfor severalminutes
so that it can level.
2. Measure the height of a reference point on
the front and rear bumpers at the center of
the vehicle.
3. Attach the trailer to the vehicle and adjust
the hitch equalizers sothat the front bumper
height is within0-.5inches (0 – 13 mm) of
thereferenceheightmeasuredinstep 2.The
rear bumper should be no higher than the
reference height measured in step 2.
