WARNING
Read all installation and operating instructions along with all labels
before using this product.
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.
Without proper knowledge, towing can be a dangerous activity.
Understand all the risks involved with towing before proceeding.
For information on towing safety, see
guide to Understanding Trailer and Towing Safety"
National Association of Trailer Manufacturers, www.NATM.com.
and your trailer manufacturer’s owner’s manual.
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.
instructions could result in serious injury or death.
Additional caution must be used when towing a wedge car trailer.
Towing stability greatly depends on keeping the center of gravity
as low as possible. Load heavy cars over the axles. Never tow
with a single car on the front of the trailer. When towing a wedge
car trailer, never exceed speeds that are reasonable for the
roadway conditions (e.g. turns, going around a curve, etc.). Failure
to account for proper trailer center of gravity and speeds that are
reasonable for the roadway conditions may cause damage to the
truck, trailer, towing components, and loss of attachment between
the truck and trailer.
Do not modify this product in any manner. Doing so could alter its
"The Trailer Handbook: A
from the
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.
Components of the hitch are heavy and cumbersome to handle.
Use proper lifting techniques when moving and handling parts.

PREPARING TO INSTALL
Remove any debris and/or obstructions from the truck
bed, this includes any plastic caps which may be over
the attachment points. It may also be necessary to
remove the plastic grommets from around the mounting
points in order to fully seat the base down to the truck.
WARNING: Whenever the slider base is being
moved, the slider handle must be in the locked
position, and the carriage must be unable to slide,
see Figure A1. Failure to ensure that the handle is in
the locked position can lead to property damage, or
serious injury.

2.
Each leg of the Companion base has an adjustable pilot
assembly which is attached to the foot with two 1/2" cap
screws, as shown in Figure B4. To adjust the pilot
assemblies that do not fit into the attachment points,
loosen both the 1/2" cap screws so the pilot assembly
can move freely, see Figure B4. Set the base over the
attachment points and adjust the pilot assemblies until
the pilot keys pass through the slot in the attachment
points and the pilot shoulders rest flat against the top of
the attachment points. When all the pilot assemblies
are aligned and inside the attachment points, push the
base towards the cab and use a tape measure to verify
that the base is approximately square with the truck
bed. Tighten any loose cap screws to 80 ft−lbs.

1.
The Companion base will mount to four attachment
points in the truck bed. Remove any debris and/or
obstructions from the truck bed, this includes any
plastic caps which may be over the attachment points.
Remove the latch pins from each side of the base and
rotate the handles out, see Figure B1. Place the base
over the attachment points and carefully lower it until
the latch cams pass through the floor and the base
rests flat against the top of the attachment points.
The latch cams and handles must be

Prepare to adjust latch tension. Once the base is

in place, remove the cotter pins from each of the four
castle nuts. Engage the cams with each attachment
point by turning the latch handles back to their locked
position, see Figure B2. If a handle will not turn easily,
loosen the castle nut until the cam will freely turn and
engage the attachment point.
4.
Adjust the tension in the latch handle, for parts list
and visual guide refer to Figures B5 and B6.
With the handles in the latched position, tighten the
castle nut until snug to increase the tension on the
latch. Rotate the latch handle open and closed.
Tighten the castle nut slightly and rotate the handle
open and closed again. Repeat this process until you
feel the cam engage the attachment point while
closing the handle. The handle is set at the proper
tension when there is friction between the cam and
attachment point but the handle can still be closed by
hand without bumping, tapping, or otherwise forcing
the handle closed.

IMPORTANT: The attachment points may differ from
truck to truck. If the pilots fit into the trucks
attachment points you may skip Step 2 and continue
with Step 3. If the Companion base does not fit into
the attachment points proceed to Step 2.
