Pre-Installation
Before beginning the installation of your new hitch, you should remove any old
equipment you have on the trailer.
Also, remove your gas bottles and set them aside. This is necessary when you get
to the Frame Bracket installation.
Many people take this opportunity to clean up the tongue of the trailer by
removing any rust and touching up the painted steel.
*Find a video of installation by searching “ProPride Hitch Installation Instructions”
on YouTube.
IMPORTANT!!!
Take the time to do your measurements.
• The more accurate the measurement, the
easier it will be for you to adjust and identify
areas to correct.
• This manual includes specific pages to log your
measurements for reference.
• If calling in for support with the adjustable
hitch bar or weight distribution questions,
please have these measurements for
reference.

Measurements
On LEVEL GROUND, take the following pre hitched measurements
Tow Vehicle:
Wheel well gap
FRONT Right_____
FRONT Left _____
REAR Right _____
REAR Left _____
Travel Trailer:
Frame Rail
FRONT _______
REAR _______
These measurements will be used for reference later when setting up weight
distribution. The goal is to have your trailer parallel to the ground, front to rear,
when hitched. A bubble level will not give you the accuracy needed.

Assembly and Installation (Reference pages 10-11)
Step 1: Determine your tow vehicle receiver height. Measure from the ground to
the top of your tow vehicle hitch receiver opening. Tow Vehicle = ____
Step 2: Determine your trailer ball height. Measure from the ground to the top
of the coupler on your trailer. Trailer = ____
Step 3: Determine your hitch box height. Subtract 5-1/2” from the trailer
measurement you determined in step 2. Hitch Box = _____
Step 4: Determine if the Hitch Bar Receiver End plates are installed UP or DOWN.
If your Tow Vehicle number is GREATER THAN or EQUAL TO your Hitch Box
number use 4A or 4B. If your Tow Vehicle number is LESS THAN your Hitch Box
number use 4C or 4D. Note: The Hitch Bar Receiver End is shown in the picture
above with the side plates facing UP.
ProPride,(Inc.( Published(01/23/2020( Page(7(
Tow Vehicle Higher Than Hitch Box
A. If your Tow Vehicle number from step 1 is 4” or MORE THAN (higher off
the ground) your Hitch Box number from step 3, use the 5/8” Hitch Pin to
pin the Hitch Bar Receiver End in your tow vehicle receiver with the side
plates DOWN. If not proceed to 4B.
B. If your Tow Vehicle number from step 1 is LESS THAN 4” OR EQUAL TO
your Hitch Box number from step 3, use the 5/8” Hitch Pin to pin the Hitch
Bar Receiver End in your tow vehicle receiver with the side plates UP. (Like
shown in the picture above)
Tow Vehicle Lower Than Hitch Box
C. If your Tow Vehicle number from step 1 is 4” or LESS THAN (lower to the
ground) your Hitch Box number from step 3, use the 5/8” Hitch Pin to pin
the Hitch Bar Receiver End in your tow vehicle receiver with the side plates
UP. If not proceed to 4D.
D. If your Tow Vehicle number from step 1 is LESS THAN your Hitch Box
Number AND LESS THAN 4” OR EQUAL TO your Hitch Box number, use the
5/8” Hitch Pin to pin the Hitch Bar Receiver End in your tow vehicle receiver
with the side plates DOWN.
Step 5: Insert the Tilt Adjustment Pin and (2)-Washers (2 extra washers are
provided) in the upper tilt adjustment pin hole. Note: If your side plates are
facing down the hole is in the end of the 2”x2” bar. If your side plates are facing
UP the hole is through the spacer between the side plates. TILT PIN WILL ALWAYS BE
AT THE TOP.
ProPride,(Inc.( Published(01/23/2020( Page(8(
Step 6: Hitch Bar Hitch End assembly. If you used 4A or 4B above your Hitch Bar
Hitch End will be like shown in the parts picture above with the adjustment holes
facing UP. If you used 4C or 4D above your Hitch Bar Hitch End will have the holes
facing DOWN.
Step 7: What is the difference between your Tow Vehicle number and your Hitch
Box Number? Difference = _____
Step 8: Slide your Hitch Bar Hitch End up or down between the side plates until
the difference between the top of the Hitch Bar Receiver End and the top of the
Hitch Bar Hitch End is approximately EQUAL TO the difference figured in step 7.
Step 9: Insert the 5/8 x 4” Hex Pivot Bolt into the LOWER pivot hole in the side
plates and through the Hitch Bar Hitch End holes that line up when you have the
proper offset from step 8. Place the 5/8 Split Lock Washer on the pivot bolt and
snug fit the 5/8 Hex nut. This is only snug fit at this time and will be wrenched
tight later. Note: This step uses the HOLE in the side plate and NOT THE SLOT.
The SLOT is the lowest location for a bolt on the side plate but in this step we use
the HOLE above the slot.
Step 10: Raise the Hitch Bar Hitch End by hand until it contacts the Tilt
Adjustment Pin.
Step 11: Insert (2) 5/8 x 4-1/2” Adjustment Bolts into the slots in the side plates.
Use (2) 5/8 USA Thick Flat Washer for each bolt. One washer under the head of
the bolt and one on the thread end of the bolt. Snug fit the 5/8 Hex nut on each
adjustment bolt.
Step 12: With all three hex bolts snug fit raise the Hitch Bar Hitch End by hand
until the slack in the Tow Vehicle receiver is taken out. The Hitch Bar Receiver
End will be tight up against the top of the 2x2 receiver at this point. Take note of
the Hitch Bar Hitch End. Is it approximately parallel to the ground? If not,
adjustment washers can be added or taken away from the adjustment pin to
make the Hitch Bar Hitch End more parallel to the ground (when hitched up).
This is to fine tune the Hitch Bar orientation and does NOT have to be completed
to complete the install.
ProPride,(Inc.( Published(01/23/2020( Page(9(
Step 13: Use a 15/16” socket and 15/16” open end wrench to tighten ALL three
bolts on the hitch bar. These bolts CANNOT be too tight. The tighter, the better.
Note: The OCL wrench provided is a 15/16” socket with a breaker bar that can
also be used to torque these bolts.

Installation
Step 1: Measure from the center of the trailer coupler along the frame to 26”.
This can be +/- 1-1/2” if the gas bottle cover or some other part is in the way of
exactly 26”. Mark the frame at this location on each side.
Step 2: Note: Jacks are Universal LEFT OR RIGHT. They can be mounted on the
LEFT OR RIGHT of the frame.
Step 3: Place the front edge of the Jack Bracket down on top of the trailer frame
at your line you marked in step 1.
ProPride,(Inc.( Published(01/23/2020( Page(15(
Step 4: Insert the U-Bolt from the bottom of the frame UPWARD through the two
holes in the Jack Bracket. Use the split lock washer and nut on the top side of the
plate and tighten with 9/16” wrench or socket. Do not put too much torque on
these bolts. No more than 30 ft-lbs is needed. More may result in the bottom of
the u-bolt bending around the bottom of the frame. This u-bolt does not require
a lot of force for the jack to work.
Step 5: Insert 1/2 x 3-1/2” Adjustment Bolt in the threaded hole on the inside of
the bracket. Pass the bolt through the hole in the shim plate and snug this bolt up
against the inside of the frame. It does not need to be tight. Overtightening the
adjustment bolt will spread the jack bracket. These bolts will need to be
retorqued a couple times before the torque sets.
Note: Shim plate MUST be used if there is a gap between frame and Jack base.
Shim plate may be modified to fit different applications. Place the shim on
inside of jack base, then lower onto frame.
Optional ½” x 4 1/2” Bolts included for C-Channel frame application.
Step 6: Complete steps 3, 4 and 5 for the other side jack.

Step 1: Measure from the center of the trailer coupler along the frame to 22”.
This measurement can be +/- 1/2” depending on final placement of Yoke
assembly. Mark the frame at this location on each side. This is the point at which
the U-Bolts slide down over the top of the frame. Loosely install center bracket at
this time, final torque will be performed after yoke tail test fitment.
Step 2: Note: If the trailer has a gas bottle tray screwed to the frame at this
location remove it temporarily. If the tray is welded it is necessary to drill two
holes for the u-bolt to slide down through the tray (this is very uncommon.) Be
sure to drill at 1” away from the edge of the tray so the bottles do no sit on top of
the u-bolts. Note: Before drilling or permanently mounting center bracket, wait
to test fit yoke tail for correct distance.
ProPride,(Inc.( Published(01/23/2020( Page(17(
Step 3: Slide the U-Bolts over the top of the frame pointing down.
Step 4: Raise the Frame Bracket upward against the bottom of the frame and
insert the 4 U-Bolt ends through the slots in the Frame Bracket.
Step 5: Slide the Frame Bracket Plates on the ends of the U-Bolts and into the
Frame Bracket channel. Snug fit the 7/16 Lock Washers and Hex Nuts up against
the plates.
Step 6: Center the two Frame Bracket down tubes directly behind the coupler.

Step 6: Tighten ONLY the two 3/4” Bolts on the main. These bolts MUST BE
TIGHT. Torque to 175 ft-lbs. Repeat on both sides of Yoke.
Step 7: Unlatch the one Over-Center-Latch (OCL) from the hitch bar.
ProPride,(Inc.( Published(01/23/2020( Page(25(
Step 8: Note: Trailer tires should be chocked before this step or whenever you
unhitch from the trailer. Pull the tow vehicle forward to clear the Hitch Bar from
them Main Hitch Unit hitch box.
Step 9: Raise the Yoke tail (pointing toward the trailer and the top of the picture
above) to between the two downward tubes of the frame bracket. The frame
bracket down tubes should be at the midpoint of the Yoke tail. You may need to
adjust the frame bracket forward or back to accomplish this. The frame bracket is
adjustable for different frame angles.
Step 10: Insert the 1/2 x 4-1/2 Yoke Tail support bolt through the down tubes
with the Yoke Tail Support Roller under the Yoke Tail and between the tubes.
Tighten the 1/2“Locking Nut on the support bolt to take up any slack in the bolt.
Note: If the Yoke Tail can be moved from side to side, tighten the nut more on
the Yoke Tail Support Bolt. Check this after a few miles of towing.
Step 11: Loosen the side bolts on the Yoke. The trailer side bolt is a pivot bolt.
The bolt in the slot, toward the tow vehicle, should be adjusted up or down until
there is approximately 1-2” between the Yoke
and the bottom of the trailer A-frame.
Note: The Yoke should be approximately
parallel with the trailer frame.Yoke pictured
under trailer frame 1-2”
Step 12: Tighten the side Yoke bolts shown in
the picture to the right to 60 ft-lbs.
Step 13: Assure Center Frame Bracket is centered,
and yoke tail centered on roller. Tighten frame
bracket U-bolts to 55 ft-lbs.

Final Installation Adjustments
Number 1: Adjust the OCL latch screws so that they snap tightly over center and
into the hitch bar. These screws are installed by the factory but can be
lengthened (unscrewed) if the OCL latch is too loose and does not snap over
center onto the hitch bar.
Number 2: Check that the hitch bar bolts are tight and torqued. These should be
very tight, 200 ft-lbs or more of torque.
Number 3: Check that the two 3/4” Yoke bolts to the main are tight. 175 ft-lbs of
torque.
Number 4: Check that all other bolts and nuts are tight. Reference PAGE 37 for all
specifications.
Note: If you did not start with the trailer and tow vehicle on level ground you
should hitch up and tow it to level ground to check that the trailer and hitch are
level. If you are not on level ground you can check that the trailer and tow
vehicle are parallel to the ground by measuring a point at the front of the trailer
and the rear of the trailer when hitched. If they are close to equal, you will be
level when towing.

Hitching and Unhitching
Hitching
Step 1: Chock your trailer tires.
Step 2: Back your tow vehicle slowly toward the front of the Main Hitch Unit until you are
about 2” from the hitch.
Step 3: Adjust the tongue jack until the hitch bar is approximately centered in the 3”x3”
hitch box opening.
Step 4: Back slowly into the Main Hitch Unit inserting your Hitch Bar Hitch End into the
hitch box. When the wedges are seated in the hitch box you will have approximately 1/8”
of the wedge showing out of the front of the hitch.
Step 5: Latch the Over-Center-Latch (OCL) on to the Hitch Bar Tab on each side. Use the
OCL Wrench included with the hitch (15/16” Socket and Breaker Bar).
Step 6: Insert the 7/16” Lynch Pin in the Hitch Bar Tab and snap the wring down over the
tab on each side.
Step 7: Raise the Weight Distribution Jack with the 3/4” Ratchet Wrench included with the
hitch. Raise the Jack on each side until you either lift the trailer off of the tongue jack or
you raise it to your desired ride.
NOTE: Using IMPACT DRILL can cause shear pin to break and is NOT a recommended tool.
Step 8: Raise the tongue jack.
Step 9: IMPORTANT – IMPORTANT – IMPORTANT – Route your tow chains UNDER the
Main Hitch Unit and BETWEEN where the Spring Bars insert in the bottom of the Main Hitch
Unit. When you are straight in line with your trailer the chains are the longest they ever
need to be. When routed properly they should hang about 1” from the bottom of the Main
Hitch Unit. *See Page 30 for photo.
Step 10: Route your electrical connection over the top of the Main Hitch Unit and plug it
into the vehicle.
Step 11: Hook up your emergency brake cable.
ProPride,(Inc.( Published(01/23/2020( Page(28(
Unhitching
Unhitching properly will make your next hitch up go more smoothly. Hitching up
is largely a result of how you previously unhitched. Once you make it routine to
follow these steps, the Main Hitch Unit will be set for your next hitching.
You can unhitch at any angle in relation to your trailer. Once you have unhitched
just leave the Main Hitch Unit hitch box facing in the direction you unhitched so
you will be able to hitch up at the same angle.
Step 1: Chock your trailer tires.
Step 2: Lower your tongue jack until it takes the load off of the back of your tow
vehicle.
Step 3: Unhook your chains, electrical and emergency brake cable.
Step 4: Lower your Weight Distribution Jack until the Spring Bar becomes loose.
This may not be when the jack bottoms out. Kick the spring bar with your foot to
recognize that there is not tension on it. At that point, STOP lowering the jack.
Repeat this on the other side.
Note: The Weight Distribution Jacks will lower in relation to how level the tow
vehicle is when you are unhitching. You can unhitch when not level but just note
that your jacks will not be all the way bottomed out.
Step 5: Unlatch the OCL on each side with the OCL wrench.
Step 6: Pull the tow vehicle away from the hitch. If you have released the tension
from the spring bars the hitch bar should slide smoothly out of the front of the
hitch.

Hitch Weight Distribution Setup
This section will detail the basic setup process for adjusting the ProPride 3P
weight distribution jacks. Below are the steps you will need to follow to ensure
that your ProPride 3P Hitch is set up correctly. Should you change tow vehicles or
trailers in the future you will want to do this again to make sure it is set up for the
new tow vehicle or trailer.
The purpose of the weight distribution jacks is to remove some of the weight
added to the tow vehicle’s rear axle and place some of it on the tow vehicle’s
front axle and some on the trailer axles. When properly set up, the trailer should
be level or slightly nose down and the tow vehicle has settled (or squatted)
evenly front to rear or slightly lower in the rear.
For optimum performance of the weight distribution hitch, the tow vehicle should
be loaded similarly as to when you would be towing. That means that you should
load all the people and cargo into the tow vehicle as if you were going on a trip
with your trailer. It may also help to have a friend take the measurements
outlined below, or find a friend that weighs about the same as you to simulate
you in the tow vehicle while you take the measurements.
If the tow vehicle has an automatic suspension leveling system, you will need to
deactivate it before coupling the trailer to the tow vehicle, but after passenger
and or cargo weight has been added.
If the tow vehicle has an air bag system, be sure to have this at its lowest
operational setting.
ProPride,(Inc.( Published(01/23/2020( Page(31(
Step 1: Level the trailer (Parallel to the ground)
• Find a level piece of pavement to park on.
• With the trailer disconnected from the tow vehicle, use a tape measure and
the tongue jack to level the trailer.
• Measure from the ground to some part on the trailer (like the frame) at the
front and at the rear of the trailer.
• Use the tongue jack to raise or lower the front of the trailer until it is parallel
to the ground. (The trailer may not be “level”, but it needs to be parallel to
the ground.)
Step 2: Measurements
• Now that you have the trailer level, it’s time to take some measurements on
both the trailer and the tow vehicle.
• Use a piece of tape to mark each spot because you will need to take the
measurements again later.
• Put a piece of tape at the spots you measured on the trailer to get it parallel to
the ground.
• Put a piece of tape at the top of the front and rear wheel openings on one side
Write down your measurements here: (You should have these already)
• Tow vehicle front wheel opening height: ________

Step 3: Hitch it up
• Chock your trailer tires.
• Back your tow vehicle slowly toward the front of the Main Hitch Unit until
you are about 2” from the hitch.
• Adjust Weight Distribution Jacks to 2”-3” to adjust the Main Hitch Units
opening to match the angle of the Hitch Bar.
• Adjust the tongue jack until the hitch bar is approximately centered in the
3”x3” hitch box opening.
• Back slowly into the Main Hitch Unit inserting your Hitch Bar Hitch End into
the hitch box. When the wedges are seated in the hitch box you will have
approximately 1/8” of the wedge showing out of the front of the hitch.
• Latch the Over-Center-Latch (OCL) on to the Hitch Bar Tab on each side.
Use the OCL Wrench included with the hitch (15/16” Socket and Breaker
Bar).
• Insert the 7/16” Lynch Pin in the Hitch Bar Tab and snap the wring down
over the tab on each side.
• Raise the Weight Distribution Jack with the 3/4” Ratchet Wrench included
with the hitch. Raise the Jack on each side until you either lift the trailer off
of the tongue jack or you raise it to your desired ride.
• Raise the tongue jack.
• IMPORTANT – IMPORTANT – IMPORTANT – Route your tow chains UNDER
the Main Hitch Unit and BETWEEN where the Spring Bars insert in the
bottom of the Main Hitch Unit. When you are straight in line with your
trailer the chains are the longest they ever need to be. When routed
properly they should hang about 1” from the bottom of the Main Hitch
Unit. *See Page 30 for photo.
• Route your electrical connection over the top of the Main Hitch Unit and
plug it into the vehicle.
• Hook up your emergency brake cable.
*NOTE~The pitch of the main Hitch Unit can be controlled by the raising and lowering
of the weight distribution jacks. RAISING the jacks will pitch the head DOWNWARD,
LOWERING the jacks will pitch the head UPWARD. This can be helpful when hitching/
unhitching when tow vehicle is not on the same plain as travel trailer.

Step 4: Measure again
• Take the same measurements you did earlier and compare them to the
originals, log these measurements on page 31 for reference.
• The “ideal” result is that the trailer sits level front to rear, the tow vehicle
squats (lowers) a bit in the front (within ½” of unhitched measurement), and
the tow vehicle squats 1”-2” in the rear (depending on total tongue weight).
• If the ideal result has not been obtained, don’t worry, it rarely happens on the
first try. Depending on where things are not ideal will determine where you
need to make the adjustments.
Troubleshooting
Let’s start with the tow vehicle.
• A. Does the tow vehicle squat correctly (a little or none in the front and the
same or a little more in the rear)?
o If yes, move on to D.
o If not, go on to B.
• B. Is the front of the tow vehicle higher with the trailer attached than it was
without the trailer attached?
o If not, move on to C.
o If yes, there is probably not enough tension on the spring bars. You will
need to increase the height of the weight distribution jacks.
• Depending on how much the difference is, will determine
the amount raised.
• Start by raising ½” to 1”. After making the adjustment, re-
measure and start again at A.
• If this does not correct the problem, it may also be
necessary to add washers to the tilt pin or readjust the
height of the adjustable hitch bar.

• C. Does the rear of the tow vehicle drop more than 1”-2” with the trailer
attached?
o If not, move on to D.
o If so, there may not be enough tension on the spring bars.
• You will need to increase the height of the weight distribution
jacks. The measurement of drop will determine the amount
you will need to raise the weight distribution jacks.
• Start by raising ½” to 1” increments and remeasuring. If this
does not correct the problem, it may also be necessary to add
washers to the tilt pin or readjust the height of the adjustable
hitch bar.
• After making the adjustment, re-measure and start again at A.
• D. Are the weight distribution jacks raised to 8” or lower?
o If so, move on to E.
o If higher than 8”, it may be necessary to add washers to the tilt pin
located in the adjustable hitch bar to change the pitch of the STINGER.
Add the washer/ washers, start again at A.
• E. Is the trailer parallel to the ground or slightly lower in the front than the
rear?
o If so, this should do it, but check out F below (just in case).
o If not, move on to F.
• F. Is the trailer higher in the front than the rear.
o If not, move on to G.
o If so, you need to lower position of the adjustable hitch bar to
accommodate the difference. See Page 6 in the manual.
If you have gotten this far, that means the tow vehicle is sitting reasonably well.
o Lowering the hitch bar will change both front and rear trailer
measurements. Ensure this change is absolutely necessary before
applying the change.
o If you choose to make the change, re-measure and start again at A.
ProPride,(Inc.( Published(01/23/2020( Page(35(
• G. Since you’ve gotten this far, the front of the trailer must be sitting lower
than the rear, so here is the final question…
o Is the height of the Hitch Bar adjustable by less than the difference in
height between the front and rear of the trailer? Now that may sound
confusing so let me give you an example.
o If the trailer is 2” lower in the front than the rear and the hitch bar can
be adjusted in 1” increments, then you need to make that adjustment,
re-measure and start again at A.
o But if the trailer is only 1” lower in the front than the rear and the Hitch
Bar can be adjusted in 1” increments, then that’s it!
Make good notes as you make your adjustments so if you make a change and it
makes things worse instead of better, you may need to make a different type of
adjustment.
Congratulations! You have successfully set up the weight distribution side of your
ProPride Hitch.
Now that you have everything hitched up and level, this would be a good time
to see exactly how tall your trailer is.
o Measure from the ground to what you think is the highest point on the
side of the trailer.
o Then climb up on the roof* to see if there is anything taller than where
you measured to, like a roof-top air conditioning unit or vent cover.
o Add the appropriate distance and add a few more inches for a safety
margin.
o Write this measurement down in your manual. You could also tape and
stick it on the front windshield pillar (driver’s side of course) or some
other convenient place. This way, when you pull into a gas station or
approach a low bridge or other structure, you’ll know if your trailer will
clear it or not.

Towing Definitions
• Gross Vehicle Weight Rating (GVWR) – The maximum allowable total weight of a vehicle or trailer that is
loaded. It includes the weight of the vehicle or trailer itself plus the passengers, fuel and cargo.
• Gross Trailer Weight Rating (GTWR) – The maximum allowable load of a trailer that is loaded. It includes
the weight of the trailer itself plus the fluids and cargo. Note: this is sometimes designated as the GVWR
of the trailer.
• Gross Combined Weight Rating (GCWR) – The maximum total load of a towed combination.
• Tongue Weight (TW) – The static downward force exerted on the hitch ball by the trailer coupler.
• Tow Rating – The allowable weight limit for a tow vehicle. GCWR minus the GVWR of the tow vehicle.
• Tow Angle – The angle created between the tow vehicle and trailer when the trailer moves away from the
centerline of the tow combination. A trailer in line with a tow vehicle has zero degrees of tow angle. A
tow angle of zero to a maximum of ninety degrees allows the trailer to be towed around a corner.
• Pivot Point – The point at which the towed trailer pivots to create a tow angle.
• Pivot Point Projection™ - Projection of the trailer's effective pivot point.
• Weight Distributing – The act of distributing the load exerted on the hitch ball, the tongue weight, onto
the tow vehicle and trailer axles.
• Wheelbase – The horizontal distance between the center of the front axle and the center of the rear axle
on the tow vehicle.
• Friction Control – Damping of trailer sway by a friction between two surfaces. The friction control works
by "stiffening" the connection between TV and TT. This causes the combined mass and rotational inertia
of the TV and TT to resist the forces which are attempting to make the TT "sway".
• Overhang – The horizontal distance from the center of the rear axle to the rear end of the tow vehicle.
• Oscillating or Oscillation – A movement back and forth between two limits over time.
• Amplitude – The displacement of the oscillation wave.
• Yaw - Yaw is the side to side movement of the trailer on the hitch ball.
• Trailer Sway – Oscillating tow angles. A tow angle created by turning a corner IS NOT trailer sway. Trailer
sway is defined as OSCILLATING TOW ANGLES. That is multiple tow angles over a period of time. The
trailer continues to oscillate away from the centerline of the tow combination at various amplitudes.
