2. Once uprights are installed; turn handles into the locked position. Adjust the T-bolts for a looser or tighter fit by
rotating them in the handles.
3. Install the cross member from kit 32998 or 32999 to uprights (#1) using the ¾”-10 bolts (#8) and ¾”-10 nylock nuts (#9).
Kit 32998 shown below as an example; kit 32999 installs similarly.
Important: install bolts on the inside of the crossmember and nuts on the outside of the crossmember.

4. Once the crossmember is installed; make sure the adaptor sits FLAT with the 5th Wheel Adaptor at ALL 4 contact locations.
Torque all four ¾”-10 bolts and ¾”-10 nylock nuts to 250 ft.lbs.

5. Rotate handles to the locked and unlocked positions. All 4 handles should rotate easily. Check to be sure that hitch
assembly (uprights & crossmember) do NOT “rock” back and forth easily and that the adaptors remain flat with the GM 5th
wheel adaptor. If the handles do not rotate easily OR if the hitch assembly “rocks” and does not stay flat; you need to
adjust the T-bolts up or down by rotating them in the handles. We recommend you do this in half turn increments. Plus, this
may take a few times to get adjusted correctly. All trucks are not made the same and require different amounts of
adjustment. BE PATIENT.
6. Rotate handles to the unlocked position and remove hitch assembly (uprights & crossmember) from the GM 5th wheel
adaptors. IF the hitch assembly does NOT remove easily; loosen the 1” jam nuts and adjust the adaptors so that the hitch
assembly easily removes. Re-tighten 1” jam nuts.
7 Once the hitch assembly removes easily, the handles rotate easily AND there is no “rock” in the hitch assembly with the
GM 5th Wheel adaptor you can tighten the 1” jam nuts with an adjustable wrench until tight.
8. Bend 1 of the tabs on each of the tab washers (5) up and against the side of the jam nut. This will keep the 1” jam nut from
loosening.

Preparing For First Use
1. Verify that the cross member is set at the proper height to provide a minimum of 6" clearance between the bottom of the
trailer nose and the top of the truck bed sides and allows for a level-towing attitude of the 5th Wheel Trailer (See Figure 1
below).
2. With top face of head level measure up to top of pickup box (dimension Y in Figure 1). On the trailer measure up from the
face of the pin box to the underneath of the trailer (dimension X in Figure 1). Measurement X less measurement Y gives the
amount of clearance between the top of the pickup box and the underneath of the trailer.
At a minimum this should be 6”, if the trailer and tow vehicle are going off-road then this needs to be 8” to 10”.
If this dimension is less than 6” DO NOT USE THIS TRAILER WITH THIS TOW VEHICLE. Severe damage may occur
to both the pickup box and the trailer.
3. If necessary, adjust the cross member to the proper height, ensuring the fasteners are re-torqued to 250 ft.lbs.
4. Ensure the 5th Wheel Trailer wheels are blocked front & rear & that the rear stabilizer jacks are fully retracted.
5. Also make sure the 5th Wheel Trailer landing leg feet are on a stable surface.
6. With hitch head level, set trailer king pin box ½” to 1” below hitch so trailer will ride up and onto hitch. Back Up the truck
under the trailer so the king pin enters the hitch.
Figure 1

7. Open the handle to your 5th wheel according to the instructions provided to that specific product.
8. Slowly back the truck so that the bottom plate of the king pin box slides onto the 5th wheel plate & the king pin slides fully
into the throat of the hitch head. Set the parking brake of the truck & place the transmission into park.
9. Visually verify that the 5th wheel slide bar or jaw has closed behind the king pin and the king pin box is resting on the 5th
wheel plate.
If using 5th wheel head 31453 (16KS): Positively lock the slide bar by rotating the handle clockwise so the handgrip is
pointing straight down at the bed of the truck. The red indicator sleeve on the handle shaft should not be visible when
correctly hitched up and the green indicator shaft should be protruding from the side of the hitch head.
If using 5th wheel head 31569 (16KW) OR 33157 (26KW): Positively lock the jaw and handle so that the handle is in the
closed position and the orange indicator is covered. The indicator should be protruding from the back of the hitch head.
Install the supplied locking clevis pin or pad lock through the lock hasp to retain the hitch closed.
NEVER LOWER THE KING PIN INTO THE HITCH USING THE TRAILER
JACKS. THIS IS A VERY DANGEROUS PRACTICE AND WILL RESULT IN
THE KING PIN SITTING ON TOP OF HITCH INSTEAD OF INSIDE. THE
TRAILER COULD THEN BECOME DETACHED FROM THE TRUCK
DURING TOWING CAUSING SERIOUS DAMAGE AND POSSIBLY INJURY
OR DEATH.
10. Before towing perform a tug test as follows: Ensure the landing gear of the 5th Wheel Trailer are extended to the
ground, chock the tires, and attach the electrical & breakaway connectors to the proper receptacles in accordance with your
5th Wheel Trailer owner's manual. Then apply the trailer brakes, and slowly try to pull the trailer forward. The trailer should
prevent the truck from moving.
11. Remove the blocks from the wheels of the 5th Wheel Trailer; fully retract the trailer jacks and double check that the hitch is
properly attached to your tow vehicle.
Uncoupling Your Trailer
1. Block your 5th Wheel Trailer wheels front & rear.
2. If necessary, start your truck & back up against the king pin to relieve pressure on the slide bar. Set the parking brake, put
the transmission into park and then turn off your vehicle.
3. Extend the landing gear of the 5th Wheel Trailer until the weight of the 5th Wheel Trailer is just off of the 5th wheel plate of
the hitch. Do not exceed 1/16" gap between the bottom plate of the king pin box and the tabletop of the hitch. Caution:
Raising the 5th Wheel Trailer too high while still connected can damage the hitch head as well as components of
your 5th Wheel Trailer. Do not extend the rear stabilizers of the 5th Wheel Trailer prior to or during uncoupling.
4. Disconnect the electrical and breakaway connectors in accordance with your 5th Wheel Trailer owner's manual. With the
rubber grip of the handle pointing straight down towards the bed of the truck, pull it straight out and then rotate it straight up
to lock the handle in the out position.
5. You are now ready to pull your truck slowly away from the 5th Wheel Trailer..
DO NOT TRIP THE HITCH MECHANISM BY HAND AS THIS CAN RESULT IN INJURY . IN NORMAL
OPERATION LEAVE THE HITCH OPEN UNLESS IT IS COUPLED TO A TRAILER.
ALWAYS PULL ON THE HANDLE TO OPEN THE HITCH BEFORE COUPLING THE TRAILER.
Never back the tow vehicle under the trailer king pin and then lower the king pin
into the hitch. This will result in high pinning and will result in hitch damage
and possible vehicle damage, injury or death!

Maintenance
1. After coupling, always visually check that the slide bar or the jaw has closed completely across the
rear of the king pin and that the indicators are working properly.
IMPORTANT! All indicating features should work when you are done hitching up for travel.
2. After the first 100 miles, and at least once a year thereafter, inspect all bolts for proper tightness. Re-
tighten nuts if needed.
3. Once or twice a week when traveling, apply a few drops of lubricant to the pivot areas of the hitch.
4. Once or twice a year, apply a light coating of wheel bearing grease to the surfaces of the slide bar that
holds the king pin in place. For best results, apply the grease with the slide bar or jaw surfaces of the
5th wheel in the closed position.
Caution: The slide bar & jaws can close with heavy force. Use extreme care to keep fingers,
hands, extremities & clothing out of the path of the slide bar. Failure to do so could result in
severe injury.
5. Periodically inspect your product for wear or damage. If excessive wear or damage is found, contact
your installing dealer or send proof of purchase and photo of wear and damage to HUSKY technical
support staff at www.huskytow.com or 1-877-544-4449.
6. Husky Towing Products recommends the use of a lube disc, contact your local Husky dealer to
purchase one.

TOWING TIPS
Driving Tow Vehicle
Good habits for normal driving need extra emphasis when towing a trailer. The additional weight of the trailer affects
acceleration and braking. Extra time should be allowed for passing, stopping and changing lanes. Signal well in advance of a
maneuver to let other drivers know your intentions. Severe bumps and badly undulating roads can damage your towing
vehicle, hitch and trailer, and should be negotiated at a slow, steady speed. If any part of your towing system “bottoms out” or if
you suspect damage may have occurred in any other way, pull over and make a thorough inspection. Correct any problems
before resuming travel.
Turning and backing up present new problems-plan ahead. It is highly recommended that a spotter be used when backing up
to alert the driver of possible obstacles and prevent jack knifing the trailer.
Towing a trailer will change your turning radius, the longer the trailer the larger radius turn.
Driving Conditions
When driving in conditions where the pavement is wet, icy, snowy, loose gravel, grass and dirt, reduce speed and do not make
any sudden maneuvers. Allow ample distance/time for stopping and changing lanes. If possible, wait for road conditions to
improve before driving.
Follow all state, local and provincial driving and towing laws in the location you are driving in.
Not following your tow vehicle, trailer, and Husky instructions/manuals can result in a fatal accident.
Check Your Equipment
Please refer to the MAINTENANCE section. Periodically check the condition of all your towing equipment and keep it in top
condition.
Tire Inflation
Unless specified otherwise by the towing vehicle or trailer manufacturer, tires should be inflated to their manufacturer’s towing
recommendations.
Towing Vehicle and Trailer Manufacturers Recommendations
Review the owner’s manual for your towing vehicle and trailer for specific recommendations, capacities and requirements.
Passengers in Trailers
Trailers should not be occupied while being towed. Most states enforce this regulation.
Trailer Lights, Turn Signals, Electric Brakes
Always hook up all of the trailer lights, electric brakes and break-away switch connection whenever trailer is being towed. Also
periodically check functionality of all lights before towing and repair any problems as needed.
Remove Hitch When Not Towing
Remove hitch from the towing vehicle when not towing a trailer to reduce chances of accidental damage and to reduce the
chance of parts being stolen.
Maintenance
Keep movable hitch assembly parts (jaw, pivot pin, etc…) lubricated when not in use.
Remove 5th wheel hitch from receiver and store in clean, dry place when not in use.
At The Beginning of Every Towing Day:
If electric brakes are used ensure the emergency break away cable is attached to the tow vehicle.
Check to see that all electrical hook-ups are in working order and that the safety chains are securely connected.
Towing safely is the responsibility of the driver of the vehicle. Failure to tow safely can result in vehicle damage, bodily injury or
death.
