7. Calculate the new weight distribution amount using the previous distances for lines A and B,
and the new distance for line C.
8. Repeat until the measurements show that the hitch is distributing weight correctly.
Step 8 – Adjust Trailer Pitch
After achieving good weight distribution, you may need to adjust the pitch or angle of the trailer
to make it level (parallel to the ground) while towing. Measure from the ground to the front and
rear of the trailer frame.
If the difference between the front and rear measurements is more than 1 ¼” adjust the hitch ball
height. Move the hitch head up or down on the shank as needed. If the difference is less than 1
¼” complete Step 9 and tow a short distance with this setup to see how it handles before making
any adjustments.
After making any adjustments to the ball height, fully hitch and engage the spring arms and
remeasure the front wheel well, for line C of the weight distribution table. Update line C and
calculate the new weight distribution percentage using the previous measurements for lines A
and B.
Make more adjustments if needed until both the weight distribution is correct, and the trailer is
level (parallel to the ground).
Step 9 – Final Tightening
After the weight distribution and trailer pitch are correct, all the bolts on the hitch must be
tightened completely to their recommended torque specifications.

You are now ready to tow the trailer. Remove the wheel chocks and connect the breakaway cable,
safety chains, and electrical cable. Adjust your brake controller correctly. Retract the jack completely.
Maintenance and Care
Friction surfaces of the head and sockets should be
cleaned and lubricated with a good quality multi-purpose
lubricant or bearing grease before each trip. This includes
the hitch ball. Lubricate the surfaces where the arm
knuckles rub. (Figure 27) Do not lubricate the spring
arms or L-brackets. We recommend Equal-i-zer high
performance lubricant. (part # 91-00-4250)
