Assembly & Installation Procedures
1. Upright and Cross Beam Assembly
A) If using pre-existing base rails ensure that the center to center (fore and aft) distance is
22” and that there are two pairs of slots in the base rails that are 20-5/8"” apart (side to
side) Otherwise contact your local dealer for proper base rail selection and installation.
B) Place the uprights into the base rails with the decals facing the rear of the truck.
Secure the uprights to the base rails using the 1/2 inch diameter clevis pins and secure
using the large hairclips in the hardware bag.

C) Install the Cross Beam.
NOTE: - The Cross Beam is adjustable in both the Vertical and the Fore & Aft
directions. There are 4 vertical mounting positions in 1” increments. 2 Sets of holes
in the Upright (item 17) provides 1” fore and aft movement from the center line of the
Uprights.
IMPORTANT:- The Center of the 5thWheel Hitch should be positioned between 1”
and 3” forward of the Center of the Rear Axle.
D) Find the center line of the rear axle and mark on the upright. Measure 1” forward of
the mark and put a 2nd mark on the upright. Find a set of bolt holes in the upright and
cross beam which positions the center of the cross beam as close as possible to this 2nd
mark, while always keeping the center of the cross beam forward of the rear axle.

E) Once you’ve found the horizontal position for the cross beam, next find the vertical
position for the cross beam.
NOTE: - If the Trailer is available for measuring follow the instructions in the section
“Operating Instructions” sub section “Preparing For First Use”. Otherwise put the
Cross Beam in the highest position per instruction (F).
F) Put the cross beam in the highest position using the pattern of holes on the end of the
cross beam. Place a flat washer, lock nut, and nut on each bolt & finger tighten.Add
shims as necessary to fill gaps. Snug down the four nuts using an "X" pattern. Torque the
nuts to 75 ft-lbs. Note: Be sure that the Cross Beam straddles the uprights. Do not over
tighten, as this will cause the uprights to fit improperly in the base rails.
2. Head and Yoke Assembly
A) Install Head & Yoke with pivot pin and castle nut. Tighten the castle nut until all the fore
and aft movement is eliminated in the pivot pin and in the head and yoke assembly. This
may require 60mm wrench or pipe wrench. Continue to tighten the castle nut until the
safety pin can be inserted. Close the clip on the locking clevis pin to secure the nut.
B) Using a grease gun, grease the Zerk fitting on the plate side of the pivot pin.
Use only the supplied bolts, nuts, and washers to install this kit. All nuts and bolts
are Grade 5 unless specified otherwise.

Understanding the Safety Features of your New HUSKY 5th
Wheel.
This Husky 5th Wheel Hitch has new features which add to the safety and ease of
operation. The most important feature to understand is that the Hitch will only fully close
when the King Pin of the 5th WheelTrailer is located correctly inside the Hitch.
Before using this 5th Wheel Hitch for the first time, the Operator needs to understand the
operation of the safety features of this Hitch.
Pull the Handle fully out, and then let it slide back while pushing it gently forward towards
the cab of the truck to miss the latch. The Hitch should partially close.
B) Looking at the front of the Hitch, the indicator should be as shown in the sketch above.
C) Using a Stick, (Keep fingers out of Jaw area) press on the Trigger Plate located
underneath the Jaw. Pressing on the Trigger Plate will release the jaw mechanism and it
will fully close. The Lock Hasp Indicator should now show that the Jaw is closed.

Operating Instructions
About Your Husky 16K W 5th Wheel Hitch
The Husky 16K W 5th Wheel Hitch System is designed to tow 5th Wheel Trailers with a Gross
Vehicle Weight Rating up to 16,000 lbs. Do not exceed the rated GVWRof your vehicle as it will
create an unsafe towing condition. It has a 4-way swivel head, its height is adjustable from 15.75
to 19.25 inches in 1-3/16 inch increments, and is removed from the bed of the truck by pulling 4
retaining pins.
Preparing For First Use
Your Husky 16K W 5th wheel system is now installed and you're anxious to be on your way down the road.
You're almost there, but take a few minutes to ensure your hitch is set up properly for your particular truck/coach
combination by following the steps below.
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 bedsides, and allows for a level-towing attitude of the 5th
Wheel Trailer (See Figure 1 below).
Figure 1
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 Ygives 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.

2. If necessary, adjust the cross member to the proper height, ensuring the fasteners are re-
torqued to 75 ft. lbs.
Coupling Your Trailer
1. Ensure the 5th WheelTrailer wheels are blocked front & rear & that the rear stabilizer
jacks are fully retracted.
2. Also make sure the 5th WheelTrailer landing leg feet are on a stable surface.
3. Pull handle fully out, then while pulling it to the rear of the truck let it slide back in until it
catches on the latch.
4. Check that the Orange indicator is not obscured by Lock Hasp. This shows the Hitch
is unlocked.
5. 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.
