If you have reached the maximum number of spacer washers, or if adjusting

the spring arms. Raise the L-brackets 1 hole. Move the spring arms back over
the L-brackets and retract the tongue jack. Re-measure the wheel wells and
check for proper weight distribution.
Repeat Steps 6 and 7 until the measurements show that the hitch is

If C is LOWER THAN A, you need LESS weight distribution adjustment.
See Line C on Weight Distribution Setup Table.
Over adjustment is a very dangerous situation where loss of control and jack-
kning is possible, especially in wet or slick road conditions.
To correct over adjustment you must take some of the weight distribution

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
