Tow Vehicles

WARNING: Serious injury or property damage can
result if the total weight of your loaded trailer
exceeds the capacity of the hitch and/or your tow
vehicle.
It is very important that you know and understand the
towing capabilities of your tow vehicle. This is espe-
cially true with the braking abilities of the tow vehicle.
You should check with your authorized dealer to see
what the capabilities are for the total towing load and
the maximum allowable tongue weight for the vehicle
you plan on using for towing.
It is also important that the lighting system in the tow
vehicle has sufficient capacity support the additional
load the trailer lighting will add to the system. A heavy
duty flasher may be required to make your turn signals
function properly.
Trailer Ball & Couplers
WARNING: Failure to properly engage the hitch ball
in the coupler ball socket and securely lock the
coupler latch mechanism can cause the trailer to
become detached from the tow vehicle while trav-
eling, which may cause serious injury or property
damage.
Ball diameter for which rating (GVWR) shall not exceed
the gross trailer weight marked on the trailer coupler.
The hitch balls have the rated load they are capable of
towing stamped Into the top of the ball.
Make sure the ball that you use to tow your trailer has
the same capacity rating as the coupler.
Do not use a different size ball than the size the coupler
is designed to use.

Before Towing

Check mounting bracket hardware for wear and proper
tightness. Replace bent, broken, or worn hardware.
Tighten hardware to 75-94 ft. lbs. Use only the
hardware provided with the Trailer. If replacement
hardware is needed, order replacement kit 8.924-
356.0.

Make sure that the trailer safety chains are properly
connected to the towing vehicle and trailer according to
SAE J684. See Safety Chain information in your
manual.
Make sure that all trailer lighting is hooked up and
working properly.
Warning: Failure to follow all installation
instructions could result in coupler failure.
Variable Height Bracket
Coupler operation must not be impaired in any way. Do
not use if coupler operation is impaired.

Bolting Instructions

Align holes in coupler and mounting bracket.
NOTE: Coupler must be secured to mounting
bracket using two sets of holes in the mounting
bracket. Insert two (2) 5/8"x4.5", grade 5 bolts
through desired mounting bracket holes and coupler.
For each bolt, Place one (1) washer at the bolt head
side and another at the bolt thread side before
assembling the nuts. Tighten lock nuts to 90-96 ft.
lbs. After installation, ensure coupler operation is not
impaired in any way. Do not use if coupler operation
is impaired. The hardware provided with the trailer
has a self-lubricating coating which is taken into
account for the tightening torque above, and is lower
than standard hardware and also is more consistent
with re-torque specifications to first-torque than
standard hardware. Order replacements with the
8.924-356.0 replacement kit, or consult your
hardware vendor for applicable, higher, torques for
the application.
