Installation
Install new pin box
NOTE: Mount the gooseneck ball in the tow vehicle
according to the instructions supplied by the manufacturer.
Instructions will vary depending on the type and complexity
of the hitch system. The height of the gooseneck pin box
can be adjusted by several inches using higher or lower
holes in the wing.
1. Hoist the gooseneck pin box into place.
2. Use a second person to line up the pin box to the bolt
holes in the mounting plate.
3. Using a drift/centering pin or screwdriver, center the bolt
holes and install at least one bolt on the roadside of the
trailer at the rear of the mounting wing.
4. Install one bolt on the curbside of the trailer at the front
of the pin box.
5. Determine if these hole locations create the proper
gooseneck pin box height.
A. The height will vary based on a number of factors:
I. The height of the gooseneck ball in the truck since
they are manufactured in a variety of different lengths.
II. The Gross Vehicle Weight Rating (GVWR) of the
trailer and the tow vehicle.
6. Utilize the holes in the wing to adjust the height of the
gooseneck pin box so the trailer is level and there is a
minimum of 6” of clearance between the top of the bed of
the truck and the underside of the trailer (Figs.2 and 3).
NOTE: The height measurement must be made with the
coupler attached to the tow vehicle and the landing gear
fully retracted.
7. With the hardware in the kit, install the bolts, washers,
lock washers and nuts.
A. The attachment sequence for the front set of holes is
just bolt and flat washer on the outside. Because there is
a support plate that runs above these holes, the box itself
has nuts that are welded on during the box assembly.

B. For the rear set of holes, install bolt and washer on
the outside and lock washer and nut on the inside of the
pin box.
8. Torque the fastening hardware to 110 to 125 ft-lbs.

1. Grease gooseneck ball. Use any of the recommended
brands of grease. See Maintenance section.
2. Make sure the 2 5/16” ball is centered under the coupler.
NOTE: Two people, including a driver and a spotter,
may be required to ensure the ball is centered under the
coupler.
3. Unlatch the coupler by pulling up on the handle and
raising the pin. Flip handle into a locked position and
ensure the plate is moving freely.
4. Lower the trailer onto the ball by fully retracting the
landing gear.
5. Latch coupler by swinging the handle out of the catch
and letting the pin drop straight through the hole in the
plate. Check to ensure the latch is in the locked position.
6. Attach the two safety chains to the tow vehicle.
7. Mount breakaway switch on the gooseneck pin box in
the same location as the Rhino pin box and attach cable.
8. Reconnect the electrical harness and other wiring
removed previously.
9. Make sure lights are functioning.
Operation
THE GOOSENECK PIN BOX CAN BE USED ONLY
WITH A 2 5/16” BALL. A SMALLER BALL WILL NOT
FUNCTION AS INTENDED AND ITS USE COULD
RESULT IN DAMAGE TO THE TOW VEHICLE AND/OR
THE TRAILER.

Maintenance
Grease gooseneck ball before each use. The grease
will reduce wear on the ball and coupler. Use any of the
recommended brands.
