See Limited Lifetime Warranty at
bwtrailerhitches.com/warranty
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.
Without proper knowledge, towing can be a dangerous activity.
Understand all the risks involved with towing before proceeding.
For information on towing safety, see
"The Trailer Handbook: A
guide to Understanding Trailer and Towing Safety"
from the
National Association of Trailer Manufacturers, www.NATM.com.
and your trailer manufacturer’s owner’s manual.
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.
Read all installation and operating instructions along with all labels
before using this product.
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
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.
