setup. A hitch that is set up poorly for weight distribution will not perform
like one that is set up well. Every tow vehicle and trailer combination will react
dierently to weight distribution.
To correctly set up weight distribution you must take 3 measurements at
dierent times on your tow vehicle. First, measure without the trailer coupled.
Next, measure with the trailer coupled, but with no weight distribution.
ird, measure coupled with the weight distribution bars tensioned.
Start by measuring the distance from the ground to the wheel well directly
above the front axle with the trailer uncoupled. See Figure 12. Record this on
LineA of the Weight Distribution Setup Table.
Back the tow vehicle to the trailer and lower the coupler onto the ball. Lock
the coupler and retract the tongue jack until it raises o the ground about 1” so
that the full tongue weight of the trailer is resting on the hitch.
Measure the tow vehicle height again, exactly above the front axle, to the
same point that you measured to earlier when uncoupled. Record this on
LineB of the weight distribution setup table above.
Measure from
ground to fender
through the center-
line of the axle.

Weight Distribution Setup Table FRONT Example
A Tow vehicle loaded for trip but still uncoupled from trailer 28”
B Tow vehicle coupled but NO weight distribution 30”
Calculate height halfway between A and B (A+B)÷2=
29”
C
Tow vehicle coupled with weight distribution engaged.
Should be at least halfway back to Line A.
Higher than this may still be under adjusted. Lower
than Line A is over adjusted. See Figure 19.
