Failure to comply with the safety information in these
WARNING
Read all installation and operating instructions along
with all labels before using this product.
Without proper knowledge, towing can be a
dangerous activity. Understand all the risks involved
with towing before proceeding. For information on
towing safety, see
to Understanding Trailer and Towing Safety"
the National Association of Trailer Manufacturers,
www.NATM.com.
Do not modify this product in any manner. Doing so
could alter its integrity and lead to a loss of attachment
between the trailer and the tow vehicle.
Regularly check that all bolted connections are at the
correct torque specification. A visual inspection should
be performed before each time you tow.
"The Trailer Handbook: A guide
instructions could result in serious injury or death.
from
Do not exceed tow or tongue rating of coupler, tow or
tongue rating of hitch, or tow or weight ratings of truck
or trailer. See vehicle and trailer manufacturer
information for ratings. Exceeding these ratings may
cause damage to towing components or loss of
attachment between the trailer and truck.
Adding components to the chassis of any vehicle can
be hazardous. There is potential for damage to
vehicle, injury from tool usage and many other
hazards. This installation must be completed by
someone who is aware of the hazards involved. This
person must be knowledgeable of proper safety
procedures for a vehicle installation of this nature, and
for usage of the equipment required to perform the
installation.
PREPARING TO INSTALL
WARNING: Components of the Companion hitch are
heavy and cumbersome to handle. Failure to use
proper lifting techniques when moving and handling
these parts could result in property damage or
serious injury.
Remove all parts from the packaging and familiarize
yourself with all the parts and tools required. Use the
parts list on the front page to verify that all parts and
hardware are present.
INSTALL PIVOT ARMS
1.
Mount the pivot arms using one of the twelve different
locations illustrated in Table A1. These twelve
locations allow flexibility in coupler height (vertical
adjustment) and distance from the cab (horizontal
adjustment). Choose a location so that your trailer will
be as level as possible and have adequate turning
clearance while towing.

WARNING: B&W also recommends that you check
the clearance between the bed side and the underside
of the front of the trailer and to allow adequate
clearance for the pitch and roll of the trailer while
towing.
2.
Locate both pivot arms, the four 3/4" threaded blocks,
eight 1/2" cap screws, and eight 1/2" split lock
washers. Place the lock washers over the cap screws.
Align the flat side of the pivot arm flat against the bolt
plate and install four 1/2" cap screws through the
holes on the arm, holding the arm in place, as shown
in figure A2. Locate the threaded blocks. Note that
the sides of the block have threaded holes on one side
and smooth bored holes on the other side. When
installing the threaded blocks it is critical that the side
with the smooth holes is flat against the bolt plate
when installed. Pass the threaded block under the
bases side and align the block with each set of screws
and start each screw, as shown in figure A3. After all
the screws are started through the arms, torque each
bolt to 80 ft−lbs.

WARNING: B&W recommends that you check the
clearance between the truck cab and the trailer.
Compare the measurement taken from the center of
the Coupler to the cab, to the measurement taken
from the center of the king pin to the farthest forward
corner point of the trailer. These measurements will
allow you to see how much clearance you will have
between the cab and the trailer while towing and
turning.

WARNING: Installing the thread blocks backwards
will not allow the pivot arms to be fully tightened in the
base and could lead to hitch failure. Before coupling
hitch, be sure that none of the 1/2" x 2" bolts are loose
and the pivot arms are securely attached to the bolt
plate. Failure to check threaded block orientation
could cause serious injury or death.
