Hitches
WARNING:
ON PICK-UP TRUCKS, the trailer hitch provided on
this vehicle enhances collision protection for the fuel system. DO
NOT REMOVE!
Do not mount a ball hitch (sometimes referred to as a trailer ball hitch
or trailer ball) to the bumper or use a hitch that clamps onto the
vehicle’s bumper or attaches to the axle. You must distribute the load in
your trailer so that 10–15% for conventional towing or 15–25% for
fifth-wheel towing of the total weight of the trailer is on the tongue.
Hitch ratings
The standard hitch has two ratings depending on mode of operation:
Weight-carrying
- requires a draw bar and hitch ball. The draw bar
supports all the vertical tongue load of the trailer.
Weight-distributing
- requires an aftermarket weight-distributing
system which includes draw bar, hitch ball, spring bars and snap-up
brackets. The vertical tongue load of the trailer is distributed between
the truck and the trailer by this system.
To determine which trailer hitch your vehicle is equipped with, refer to
the trailer hitch label located on trailer hitch cross tube. Once you
determine which trailer hitch you have consult your authorized dealer,
