The standard integrated hitch has two ratings
depending on mode of operation:
•
Weight-carrying mode requires a draw
bar and hitch ball. The draw bar supports
all the vertical tongue load of the trailer.
•
Weight-distributing mode requires an
aftermarket weight-distributing system,
which includes draw bar, hitch ball, spring
bars and snap-up brackets. This system
distributes the vertical tongue load of the
trailer between the truck and the trailer.

Weight-distributing Hitch - Vehicles without
Automatic Leveling Suspension
WARNING
Do not adjust a weight-distributing
hitch to any position where the rear
bumper of the vehicle is higher than it was
before attaching the trailer. Doing so will
defeat the function of the weight-distributing
hitch, which may cause unpredictable
handling, and could result in serious personal
injury.
When hooking-up a trailer using a
weight-distributing hitch, always use the
following procedure:
1. Park the loaded vehicle, without the
trailer, on a level surface.
2. Measure the height to the top of your
vehicle's front wheel opening on the
fender. This is H1.
3. Attach the loaded trailer to your vehicle
without the weight-distributing bars
connected.
4. Measure the height to the top of your
vehicle's front wheel opening on the
fender a second time. This is H2.
