FOLDING HITCH BALLS
The Atwood Folding Hitch Ball is a hitch ball designed to be mounted
on a pickup truck, positioned above and forward of the rear axle for
towing gooseneck type trailers.
Max. Gross Vehicle Weight: 25,000 lbs.
Ball Size: 2-5/16˝ diameter
Tongue Load: 5,000 lbs.
For larger trucks, contact the vehicle manufacturer or Atwood
Mobile Products for recommendations.
To adequately transfer towing forces to the truck, the folding hitch ball
must be supported by a structure that ties the folding hitch ball into
the truck frame. The Atwood Under Truck Installation Kit is a complete
bolt-on support structure. Fabrication instructions for an alternate sup-
port structure using the Bed Plate or H Frame method of installation
are also included.

INSTALLATION
CAUTION
VEHICLE DAMAGE
For adequate transfer of forces produced during towing these
instructions MUST be followed.
1. Raise truck at frame so that the weight will be taken off the suspen-
sion and rear wheels will be away from wheel well openings. This
will give more access to the side of the truck frame where the
mounting plates will be installed.
2.
VEHICLES EQUIPPED WITH EXHAUST HEAT SHIELDS AND/OR WHEEL WELL LINERS -
Temporarily remove shields and liners to provide adequate space for
installation of long cross angles and side frame mount brackets.
Keep these parts for replacement after hitch installation.
3. Place carriage bolts in square holes at the ends of the angles.
4. Slide cross angles (long) in between frame and bed under the vehi-
cle, one end at a time (the downward portion of the angles will be
facing each other)
FIG 3 & 4.
5. Insert side frame mounting brackets (end with slots) from side of vehi-
cle between vehicle frame and angles installed in previous step
FIG 5.
6. Loosely bolt cross angles to side frame mount bracket (14˝ long) FIG 5.
CAUTION
VEHICLE DAMAGE
The center of the ball must be 2˝ to 6˝ in front of axle centerline.
The position of the ball must allow for proper clearance between
trailer and both rear of cab, and rear corner of truck bumper when
making turns of up to 90°.
7. Position the center of the frame mount brackets 2˝- 6˝ forward of the
rear wheel axle centerline (providing adequate clearance for brake,
electrical and fuel systems)
FIG 6.
8. Center the long cross angles on the vehicle from right to left. This is
key to having the folding ball assembly centered in the bed
FIG 4.
Check installed cross angles to be sure that they are square with
the truck frame.
WARNING
PERSONAL INJURY / VEHICLE DAMAGE
DO NOT CUT gas lines, brake lines, electrical wiring, etc. when mak-
ing cutouts or drilling holes in truck.
9. From the under side of pickup truck, mark the center of holes in
bed using the hitch as a template. Drill holes to fit carriage bolt
using a 3/4˝ drill bit
FIG 4.
10. Before cutting 12-7/8˝ x 8˝ hole in bed of vehicle be sure to recog-
nize the hole must be offset 2-1/8˝ towards the driver’s side for ball
to be centered in truck bed
FIG 2.
11. Make cutout on the floor of truck bed. See FIG 1 & 2.
