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 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.

BALL HEIGHT
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).
ASSEMBLY & SETUP
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).
