and trailer separation while towing.

Gross weight of trailer must not exceed 16,000 pounds for this product.
Goose Ball vertical weight must not exceed 3,200 pounds (See Fig. 6). If in doubt have
Goose Ball weight measured by qualified facility.

Vehicle Tow Rating: ________________.
Goose Box Rating:______________.
*Gross Trailer Weight (Figure 5):________________.
*Trailer weight should be the lowest of these recorded ratings for safe towing conditions.
2. The Goose Box is designed for a maximum of 20% Gross Trailer Weight on the Ball (Goose Ball Vertical Weight). See Fig. 6
Figure 6
20% MAX. GROSS
TRAILER WEIGHT
(BALL WEIGHT)
3. The Height of the Goose Box should be adjusted in the wing set so there is a minimum 7 in. clearance between the top of the bed
and the underside of the front of the trailer for pitch and yaw of the trailer (See Figure 7). This should be checked with the Goose
Box air bag inflated to 40psi. It is recommended that the Goose Box be mount in the wing set one position lower than the original

ASSEMBLY INSTRUCTIONS
1.Before removing the original pin box, take note of height of the original pin box, use this as a starting reference point for the
height of installing the Goose Box into the mounting wing set. (See Figure 8) The Goose Box comes with all new hardware to
be used. There is enough hardware for four bolts per side. Refer back to Figure 4 for bolt, washer, and nut installation.
Figure 8
Mounting Wing Set
2. Remove the existing pin box, taking care to remove any necessary wiring and/or break away switch if attached to the
pin box. (If removed, the break away switch and wiring must be reinstalled after installation is complete. The break
away switch can be mounted on the side of the Goose box or side of wing, but Do NOT drill or screw on the side of the
Goose Box forward of the air fill bracket.)
3. Install the Goose Box inside the mounting wings (Figure 9), Cequent Performance Products recommends using the hardware kit
included with the Goose Box. (4 bolts per side, 2 front row & 2 rear row) It is all grade 8 hardware. Install at least the hardware
included as a minimum. Torque all bolts to 210 ft. lbs.
Figure 9
Note: Installing the front top bolt of the Goose Box first may ease alignment.
Note: It is recommended that you install the Goose Box
one (1) position lower than the original pin box.
WARNING: The Goose Box is heavy, take care to maintain adequate
support under the Goose Box arm until at least 2 bolts per side are installed.
Failure to do so may result in death or serious injury.

MAINTENANCE:
1.Grease coupler shaft from fitting in back of coupler before each use and grease goose ball before each use..
2.Keep Goose Box painted to prevent rust and maintain a good appearance. (Do Not Paint Over Labels)
3.No special instructions for storage, perform normal maintenance when taking out of storage and using again.
ADJUSTING THE AIR SPRING
1.Perform the hitching procedure before adjusting suspension air pressure.
2.With trailer hitched to truck and landing gear / jacks retracted, Add air to the air spring at the valve shown in figures 12A, B, & C.
3.Continue adding air until the label on the rear driver’s side is in the green. (Figure 12C) Note:Do NOT exceed 50 psi. Starting Operating Pressure Should Be Around 35-40 psi.
4. It may be helpful to put tow vehicle in drive, move a few inches, and then apply brake.
This will jounce the unit and let it find it’s natural position.
5. Recheck Air
The label is a good reference for setting air pressure in the spring, if more performance is desired the air bag
pressure can be adjusted to suite your preference. A good starting point for pressure setting is 35-40 psi. (Do Not Exceed 50 psi). If the ride is too soft, add more pressure. If the ride is harsh, remove pressure.

Note:
The Goose Box is equipped with an
automatic air relief valve. If you try to
over inflate the bag the relief valve will
pop, releasing excess air. The system can
help you adjust the air bag. Fill to green
area, and then add a few more pounds of
air pressure. Drive your unit and step on
the brake a few times. Excess air will vent
off. You should be left with the unit near
or in the green area. This should be your
most optimum air pressure.
1. CHECK YOUR EQUIPMENT: Check that condition of all of your towing equipment and keep it in top condition.
2. Check to see that all bolts are properly tightened.
3. Check that the airbag pressure is set for your coach. (The label in rear should be in the green zone.)
