WARNING
Over or under adjusted weight distribution decreases tow vehicle stability.
Under or Over Adjustment:
If the hitch is transferring too little or too much weight, you must make
adjustments to the hitch setup. For changes during the initial setup we
recommend adding or removing spacer washers rst to try and keep the spring
arms parallel with the trailer frame. In our experience, this can improve the
performance of the sway brackets. It also gives you more adjustment options if
needed later.
Once the maximum (9) or minimum (5) number of spacer washers has been
reached, further adjustments can be made by raising or lowering the L-brackets.
Minor adjustments later for changes in loading can usually be done by moving
only the L-brackets.
NOTE: e distance from the tow vehicle rear axle to the hitch ball sig-
nicantly aects how the tow vehicle reacts to weight distribution adjust-
ments. e same washer or L-bracket change will have varying results on
dierent vehicles.
Under adjustment occurs when there is not enough weight being transferred
to the front axles of the tow vehicle. See Figure 17.
If C is still HIGHER THAN calculated halfway point, you need MORE
weight distribution adjustment. See Line C on Weight Distribution Setup
Table. With an under adjusted setup your hitch is not unloading the rear axle
suciently, giving back as much steering control as it could, nor is it providing
as much friction as it could to help reduce trailer sway.
To correct under adjustment you must add more weight distribution force to
the hitch by adding spacer washers, or raising the L-brackets.
If this is the initial set up, use the tongue jack to unload the spring arms.
Remove the spring arms from the hitch head. Uncouple the trailer and pull tow
