Mild automotive detergent may be used to clean the product. Do not use dish detergent, abrasive cleaners, abrasive pads, wire brushes or other similar products that may damage the finish.
WARNING
Never exceed the vehicle manufacturer’s recommended towing capacity. The
ratings of the mount system are intended to represent the capability of the
product and in no way reflect the ratings or capacity of the towing system it
is being used with. The consumer
or operator are strongly advised to learn the ratings of the various
components of the towing system and never exceed the limits of the lowest
rated component being used.
Use of any pin other than that of the mount system manufacturer could be a
serious safety hazard and will void the warranty.
Never hook up trailer safety chains to the mount system. Ensure the safety
chains operate freely around the mount system and do not become entangled.

Step 1 – Insert into the Trailer Hitch
Begin by installing the shank (#1) into the trailer hitch receiver and secure
it with a hitch pin and clip (sold separately).
Step 2 – Determine Required Ball Height
Determine the proper ball height by leveling the trailer and measuring from
the bottom of the trailer tongue to the ground, see below.
Find the hole closest to that measurement on the adjustable shank (#1).
The trailer ball platform (#2) will be centered on that hole.
Step 3 – Attach the Tongue
Based on the determined ball height, slide the tongue onto the shank and align
with the proper hole locations.
Angle the tongue slightly upwards and press in toward the shank.
Insert a pin (#3) into the top tongue hole first. To pin the bottom tongue
hole, apply downward force to the tongue, and slide the second pin into place.
Note: The highest mounting position will require the bottom pin to be
installed first with the tongue angled downward.
Then, apply force upwards to install the second pin.
Secure all pins with the included clip (#4).
WARNING
The provided pins are specifically engineered for this system.
If replacement pins are needed, they must be replaced with original factory
mount pins (CURT# 45931).
