Highest Measurement
Lowest Measurement -(minus)
Difference between highest and lowest
If the difference between the highest and lowest measurement is 1-1/4”
or more, you should try adjusting the hitch ball height. If it is less than
1-1/4” different, complete Step 8 and tow a short distance with this setup to
see how it handles before making any adjustments.
If the higher measurement is the front of the trailer, move the hitch head
down 1 hole position on the shank. If the lower measurement is the front of
the trailer, move the hitch head up 1 hole position on the shank.
Adjustments made to ball height directly affect how weight is distribut-
ed. Moving it up on the shank slightly reduces the amount of weight distri-
bution you get from a particular setup. Moving it down slightly increases the
weight distribution.
After making an adjustment to the ball height, return to Step 6 and check
the weight distribution measurements again. Re-adjust the weight distribu-
tion if necessary until it falls within the instruction guidelines. Re-check the
trailer angle again to see what difference has been made. You may need to
try several setups before you get one that shows good weight distribution
and trailer angle.
Step 8 - Final Tightening:
Do not tow your trailer until all bolts and nuts have been checked and
properly tightened, and all pins and clips are securely in place.
When you feel that the number of spacer washers and L-bracket position
are giving you good weight distribution, and that the trailer is sitting at a
good angle, tighten all of the nuts and bolts securely. With the weight dis-
tribution engaged, begin with the angle set bolt, and tighten it until it comes
back into solid contact with the shank plus 1/4 turn. Then tighten down both
3/4” shank bolts to 320 ft. lbs. torque.
Double check the nuts holding the L-brackets to make sure they are
tight, and also the bolts holding the sway bracket assembly to the trailer to
