Very good point. The physics behind it is based on the spring arms. Where the normal hitch has flexible connection that allows for a sag, the spring loaded arms push back and create more like a hard, rigid connection. It is like replace chain with a solid bar. Because it is not bendable, the rear axle does not squat as much as before.
I finally understood it watching this video. Think of it like instead of a ball coupling, you had a door hinge connection that could only swivel left and right. The joint between trailer and truck would not bend up or down, therefore the squatting could not occur. The weight distribution hitch uses springs to achieve this effect, but with a little bit of give so that going over hills it can still bend up and down. Just requires extra force to do so. So you'd only sag going over bumps or dips.
It should work no different than a regular distribution hitch. It simply has a gauge and a torque bolt to adjust it. The biggest problem I see is it increases the distance from the rear axle t to the ball which gives more leverage to the trailer for both weight and sway that must be compensated by the distribution - sway bars. I would love to see a redesign that puts the ball as close to the bumper as possible.
@@heavymetalmechanicX Me TOO. I have yet to see ANY video tell you HOW it works, not just what it does. BUT. I will tell you how it actually works. What these things do is restrict the downward pivot of the ball and hitch. IF you took a 2" square tubing and welded it to the trailer and stuck it in the receiver you would have NO sag at all. Of course you wouldn't be able to turn. If you took a long leaf hinge, opened it and placed it on two round tubes, the hinge would just collapse. And the ends of the hinge go up. But if you took a paint mixing stick and clamped it to one leaf, of the hinge and took a rubber band and strapped it to the other leaf, it would straighten that hinge right back up. The two ends, pin and knuckles will all get straightened out. The two round tubes represent the tires of the trailer and the rear tires of the truck. The ends of the hinge are the front tires of the truck and tail end of the trailer. The hinge pin and knuckles are the ball and hitch. So you can see how it actually brings that front end back down What all these videos never say is that when you are tensioning the bars with chains or like this one with a fancy tensioner is that all you are doing is getting the right stiffness so that the ball has SOME movement up and down. That right there is why you will never see them putting these things on utility trailers because the weight changes way too much. Boats and travel trailers don't change much. OR at least enough to makes a difference. I hope this makes sense?

At the 1:40 mark, you can see how it torques upwards on the hitch. So applying force from the back of the trailer tongue hitch up and into the truck hitch which exerts into the truck frame basically, which makes the front receive some of the weight. It's just a lever from the trailer hitch tip to back sides of the trailer hitch where they connect that pushes outwards both ways and counteracts against the ball/hitch point. The truck front springs and trailer axle springs can absorb the force(weight).

Sam is right that this video th-cam.com/video/AkK9uktf32E/w-d-xo.html shows the principle of how it actually works but he goes over it so fast and leaves out why the bars have chains. Look at my comment to the others here where I explain it.
I'm trying to understand how this works, the bars are acting as levers and pulling the tongue up. But I still can't figure out why the truck levels- the tongue weight hasn't changed. I guess using the lever arms effectively moves the hitching point backwards?
I think what it does is it kinda stops the rotation on the ball of your hitch, witch then pulls the trailer up. So it's pretty much putting tremendous pressure on the ball and chains of the hitch, aswell as I'm assuming off road the hitch doesn't work, as you no longer have the ability to go up and down hills, as your truck and trailer are sorta "one" object that can only rotate left and right..
I still dont get it...does a weight disteibution hitch distributes the tongue weight to both the towing vehicle and back to the trailer? meaning out of for example 1000lbs tongue weight originally i now only have 750lbs tongue weight and 250 go back to trailer? does that mean my vehicle about 20% heavier load? why should i not ever use a weight distribution hitch then?
Correct! The Distributed Tongue Weight (what you adjust the scale to be set at) is the amount of weight that is being distributed and isn't changing your actual/initial tongue weight.
@@weighsafe Please help me understand. If 15-20% of the tongue weight is redistributed to the trailer's front axle...then its actually reducing the weight of the tongue on the truck. Right? I understand that the tongue weight is still there, but the truck doesn't take 100% of that weight...Right? For example: It the tongue weight is 1000 lbs and 150 lbs are redistributed to the front axle of the trailer (the trailer is taking some weight off the truck), the truck will only received 850lbs of the total weight on it. Right?

How are you supposed to drive through a creek crossing or turn around on a single lane mountain road or un level camping areas with one of those leveling devices binding up the hitch? Why not just get a truck that doesn’t squat when you put a trailer on it?
This would be a lot better with a very basic model of how this works -- reduce it down to basics like those old 1940s videos with sicks and weights and demonstrate how changing the lever arm is actually changing things or whatever.
Sorry if this is a dumb statement but I just don't understand how they work. I understand they are like handles to a wheel barrow and the higher you lift the weight gets distributed but, I don't know..... It seems like you are trying to pick yourself up while you are standing in a bucket.

"How A Weight Distribution Hitch Works" These things are very wrongly named. They don't distribute weight at all. All these things do is restrict something from happening and that's it.
No. Good question. The true tongue weight stays the same. When the weight distribution system is set up and weight is distributed correctly, then you will actually have more tongue weight applied to the tow ball. This is called Distributed Tongue Weight (DTW). Please reach out with any further questions. support@weigh-safe.com
thanks! it is a bit confusing but I believe I am starting to understand conceptually how it works (hopefully). The total weight in the truck hitch once the WD bars are in place has to be lower, but the total pressure on the tow ball is higher because of the combined effect of 2 leverages going in 2 different directions, down due to the original tongue weight and up due to the WD bars.
This is the second video i watched that shows the weight being distributed back to the trailer axle not the front axle of the truck I believe most people think its goes to the front axle of the truck . So who is correct ? When do you know when you need one ?
@@davidmatt904 Both. The WD bars produce an upward torque effect at the towing vehicle hitch, decreasing logically both the weight on front and rear axles. The WD bars also produce a downward torque at the tongue of the trailer, increasing the weight on the trailer axle.

This does not tell us how it works. It only tells us "how to work it" - that is, how how operate the device. I clicked this thinking it would tell me how weight distributing hitches work. It does not.
This only happens if 1 = you have a poorly designed trailer with the axles set top far back, or 2, you are too cheap to buy a proper ball drop for your truck. Been towing my whole life and a weight distribution hitch does nothing for stability or safety
Worst customer service ever. My scale leaked after 2 uses. They sent me out another one for me to install snail mail. When I finally got it they sent the wrong parts. Now waiting again for the right part. One of the most expensive distribution hitches and the worst customer service. Some guy working from home sending out the wrong parts. Instead of just sending me a new hitch and me sending mine back collect. Wouldn't recommend this hitch cause they don't stand behind their product.
As long as I've been pulling trailers, calling curt hitches, even their tech guru's which are impossibly poor explained, thus why I've never found a common sensible video just showing basis mechanical physics..Layman's terms using a damn pointing stick saying when you do this, that is what happens..Spring arms and chain is an entirely different concept than solid bars, yet achieves the same result. One fact needs to be understood. Marketing..Companies will heavily relie that the average(99.8% of people don't care how it works, just that it does work). This unit claims that weight is actually transferred back to the trailer verses transferring weight to the trucks front axles..Its a choice on how to explain.. I'll attempt to explain by basic mechanical physics..The clamped portion on the trailer frame has little to do with anything..That clamped portion has downward pressure, or it would be ripped right up and off..Until I'm capable of making a video on You Tube, it will seem impossible to explain. It's a push and pull aspect at two points. It's rather ingenious, yet no different than the principles of the late Manitowoc cranes. Hell even cantilever. A downward pressure creates an upward movement, or lets say more importantly a "lesser"downward pressure at a midpoint..weight transfer..Weight distribution..A common bridge made of precast concrete cantilevers. Internally they have the equivalent of spring steel..Yet the spring steel hitches aren't quite the same as solid bar hitches. People, one inch of hitch length to the ball means a lot, a lot!!!..Spring steel type are not the solid bar type, even though carrying loads..Remember, there only needs to be a compensation transfer on big trailers from 500 pounds. Maybe 7 or 800 pounds. Given the tongue weight of 1,000, to 1500 hundred..Every trailer by specs needs a minimum downward pressure to keep the ball hitch intact..But here we have both a unique in unison equilibrium of both upward and downward pressure. The downward pressure is more than enough to overcompensate upward pull. Notated upward pull..Something can in fact be pulled upward from the clamp/jaws of your locked tongue hitch, yet having substantial downward pressure exceeding that by about 66 percent. Anyone who has ever set their trailer knows you're lifting your entire truck and trailer just to set the weight distribution hitch. Rise and fall into place..You're tongue hitch is clamping in place momentarily to make that happen..The trailer manufacturer says, no, you need a minimum of downward pressure by common law on that ball hitch..But weight distribution is different that it's both controlling a modified push and pull effect. Engineers should not laugh at my limited engineering in sound acoustics with a dual voice coil speaker. (Transducer, ,which is actually a piston assembly). A mechanical assembly quite not unlike a car engine, a cam shaft pushing and pulling in unison..The dual coil speaker is like ,we don't want to extend too far that is blows apart..Because their friends in science are vigilantly monitoring the pull back..Equilibrium, the more power does not change the factor. Mechanical physics (mathematics), can not lie..Your weight distribution clamps 3 feet to the rear on the trailer frame from the ball point, is in fact pulling your entire truck rear upward. Why would people misunderstand that, I've explained, there is still greater downward pressure on the tongue, by at least two thirds. Perhaps religiously 60 percent. Your trailer might have a 1200 pound tongue weight, but in weight distribution it only needs to be 800. That's a huge fricking difference between your truck, be it 2500 ,3500hundred, or Ford 250/350. Or if you're dumb enough to pull a 38 foot travel trailer with a 1500, or 150...My f250 xlt diesel has the identical commercial towing package of the f350. Including rear 4 inch blocks. I'm not here to debate with Ford owners. I'll help you if Ford is confusing.. Same front and rear springs as f350, same anti sway bar, same 4 inch rear lift blocks. Only difference is the f350 frame that can tow beyond 19,000 pounds up to 30 plus. Off that subject. This video truck hitch is a bit unique. And I'll respectfully challenge them. Inside their hitch box that we can't see is a ,or better be a damn well engineered pivot point with crafted tensiled steel that can at center bear the weight repeatedly. Made by their claim of a simple rotary bolt adjustment. I'll claim BS, that it only has a 2 inch adjustment at best. Not 3 to 5.. And the scale, which most likely is faultable, isn't necessary. You just added 10 inches plus to my hitch, which means if your product fails, so does my trip. Blue oxe, over priced. Curt same technology yet a non chain assembly. Better for less money. This company hasn't even talked about sway control. There's no way their pivot point can capitalize on that. Give this Ford owner with a pulling machine, pulling a 35rlts grand design bumper pull, 3pull outs, 38 foot length, and I'll sell your product religiously for free if it works.
This is a good depiction of WHAT the hitch does, not HOW it works. Seriously, how the heck does it work?

Cause and effect and how to correct it. Lacks description on how hitch works to achieve results ... only describes what is does.
This would be a lot better with a very basic model of how this works -- reduce it down to basics like those old 1940s videos with sicks and weights and demonstrate how changing the lever arm is actually changing things or whatever.
Sorry if this is a dumb statement but I just don't understand how they work. I understand they are like handles to a wheel barrow and the higher you lift the weight gets distributed but, I don't know..... It seems like you are trying to pick yourself up while you are standing in a bucket.
Very helpful, thanks!
Waste of time! You should change the title to "I'll tell you that the weight distribution works".
I have yet to see ANY video tell you HOW it works, not just what it does. BUT. I will tell you how it actually works.
What these things do is restrict the downward pivot of the ball and hitch. IF you took a 2" square tubing and welded it to the trailer and stuck it in the receiver you would have NO sag at all. Of course you wouldn't be able to turn.
If you took a long leaf hinge, opened it and placed it on two round tubes, the hinge would just collapse. And the ends of the hinge go up. But if you took a paint mixing stick and clamped it to one leaf, of the hinge and took a rubber band and strapped it to the other leaf, it would straighten that hinge right back up. The two ends, pin and knuckles will all get straightened out. The two round tubes represent the tires of the trailer and the rear tires of the truck. The ends of the hinge are the front tires of the truck and tail end of the trailer. The hinge pin and knuckles are the ball and hitch. So you can see how it actually brings that front end back down
What all these videos never say is that when you are tensioning the bars with chains or like this one with a fancy tensioner is that all you are doing is getting the right stiffness so that the ball has SOME movement up and down.
That right there is why you will never see them putting these things on utility trailers because the weight changes way too much. Boats and travel trailers don't change much. OR at least enough to makes a difference.
I hope this makes sense?

Actually the front axle on the trailer also takes on more weight because now the Trailer tilted forward
Amazing
You should have explained how it works using a free body diagram.
"How A Weight Distribution Hitch Works" These things are very wrongly named. They don't distribute weight at all. All these things do is restrict something from happening and that's it.
And then if you attach another chain with a crossbar and hydraulic cylinder, it will improve your fuel economy. And make your breakfast too!
So does this mean that the tongue weight decreases when the weight distribution bars are in place?
No. Good question. The true tongue weight stays the same. When the weight distribution system is set up and weight is distributed correctly, then you will actually have more tongue weight applied to the tow ball. This is called Distributed Tongue Weight (DTW). Please reach out with any further questions. support@weigh-safe.com
thanks! it is a bit confusing but I believe I am starting to understand conceptually how it works (hopefully). The total weight in the truck hitch once the WD bars are in place has to be lower, but the total pressure on the tow ball is higher because of the combined effect of 2 leverages going in 2 different directions, down due to the original tongue weight and up due to the WD bars.
This is the second video i watched that shows the weight being distributed back to the trailer axle not the front axle of the truck I believe most people think its goes to the front axle of the truck . So who is correct ? When do you know when you need one ?
@@davidmatt904 Both. The WD bars produce an upward torque effect at the towing vehicle hitch, decreasing logically both the weight on front and rear axles. The WD bars also produce a downward torque at the tongue of the trailer, increasing the weight on the trailer axle.
@@Larry_Kabberga UM No. You guys are over thinking it. I have yet to see ANY video tell you HOW it works, not just what it does. BUT. I will tell you how it actually works.

Don't put a leveling kit on your trucks people. The manufacturer has lots of hours in designing your vehicle
ya, but damn near all of the recommend using a load leveler at weights over 5klb
This only happens if you load the trailer unevenly.
It’s more necessary for a camper that you don’t “load” but could already be heavy on the tongue.
This video would be better if it described how a weight distribution hitch works.
Like all engineers, you talk a lot and you say nothing
you’re showing us examples of WHAT happens but
you don’t show us HOW !!!!!!
When you call the back of the truck "the back of the trailer"... just give up at that point.
It would be great if you could prove the physics with a live action video instead of a cartoon.
This is WHAT happens not HOW
This video made me more confused about how it works
This does not tell us how it works. It only tells us "how to work it" - that is, how how operate the device. I clicked this thinking it would tell me how weight distributing hitches work. It does not.
so it doesn't distribute weight... it puts tension on the hitch... bending against the weight... sounds like snake-oil to me
This only happens if 1 = you have a poorly designed trailer with the axles set top far back, or 2, you are too cheap to buy a proper ball drop for your truck. Been towing my whole life and a weight distribution hitch does nothing for stability or safety
hey man I swear by this
did not explain how it works
...or you could just load your trailer so that it's properly balanced...
Or you can learn to load your trailer nice and evenly.
This is totally useless, since you never explain how the darn thing works!!!
Worst customer service ever. My scale leaked after 2 uses. They sent me out another one for me to install snail mail. When I finally got it they sent the wrong parts. Now waiting again for the right part. One of the most expensive distribution hitches and the worst customer service. Some guy working from home sending out the wrong parts. Instead of just sending me a new hitch and me sending mine back collect. Wouldn't recommend this hitch cause they don't stand behind their product.
Whaaaaaa?
As long as I've been pulling trailers, calling curt hitches, even their tech guru's which are impossibly poor explained, thus why I've never found a common sensible video just showing basis mechanical physics..Layman's terms using a damn pointing stick saying when you do this, that is what happens..Spring arms and chain is an entirely different concept than solid bars, yet achieves the same result. One fact needs to be understood. Marketing..Companies will heavily relie that the average(99.8% of people don't care how it works, just that it does work). This unit claims that weight is actually transferred back to the trailer verses transferring weight to the trucks front axles..Its a choice on how to explain.. I'll attempt to explain by basic mechanical physics..The clamped portion on the trailer frame has little to do with anything..That clamped portion has downward pressure, or it would be ripped right up and off..Until I'm capable of making a video on You Tube, it will seem impossible to explain. It's a push and pull aspect at two points. It's rather ingenious, yet no different than the principles of the late Manitowoc cranes. Hell even cantilever. A downward pressure creates an upward movement, or lets say more importantly a "lesser"downward pressure at a midpoint..weight transfer..Weight distribution..A common bridge made of precast concrete cantilevers. Internally they have the equivalent of spring steel..Yet the spring steel hitches aren't quite the same as solid bar hitches. People, one inch of hitch length to the ball means a lot, a lot!!!..Spring steel type are not the solid bar type, even though carrying loads..Remember, there only needs to be a compensation transfer on big trailers from 500 pounds. Maybe 7 or 800 pounds. Given the tongue weight of 1,000, to 1500 hundred..Every trailer by specs needs a minimum downward pressure to keep the ball hitch intact..But here we have both a unique in unison equilibrium of both upward and downward pressure. The downward pressure is more than enough to overcompensate upward pull. Notated upward pull..Something can in fact be pulled upward from the clamp/jaws of your locked tongue hitch, yet having substantial downward pressure exceeding that by about 66 percent. Anyone who has ever set their trailer knows you're lifting your entire truck and trailer just to set the weight distribution hitch. Rise and fall into place..You're tongue hitch is clamping in place momentarily to make that happen..The trailer manufacturer says, no, you need a minimum of downward pressure by common law on that ball hitch..But weight distribution is different that it's both controlling a modified push and pull effect. Engineers should not laugh at my limited engineering in sound acoustics with a dual voice coil speaker. (Transducer, ,which is actually a piston assembly). A mechanical assembly quite not unlike a car engine, a cam shaft pushing and pulling in unison..The dual coil speaker is like ,we don't want to extend too far that is blows apart..Because their friends in science are vigilantly monitoring the pull back..Equilibrium, the more power does not change the factor. Mechanical physics (mathematics), can not lie..Your weight distribution clamps 3 feet to the rear on the trailer frame from the ball point, is in fact pulling your entire truck rear upward. Why would people misunderstand that, I've explained, there is still greater downward pressure on the tongue, by at least two thirds. Perhaps religiously 60 percent. Your trailer might have a 1200 pound tongue weight, but in weight distribution it only needs to be 800. That's a huge fricking difference between your truck, be it 2500 ,3500hundred, or Ford 250/350. Or if you're dumb enough to pull a 38 foot travel trailer with a 1500, or 150...My f250 xlt diesel has the identical commercial towing package of the f350. Including rear 4 inch blocks. I'm not here to debate with Ford owners. I'll help you if Ford is confusing.. Same front and rear springs as f350, same anti sway bar, same 4 inch rear lift blocks. Only difference is the f350 frame that can tow beyond 19,000 pounds up to 30 plus. Off that subject. This video truck hitch is a bit unique. And I'll respectfully challenge them. Inside their hitch box that we can't see is a ,or better be a damn well engineered pivot point with crafted tensiled steel that can at center bear the weight repeatedly. Made by their claim of a simple rotary bolt adjustment. I'll claim BS, that it only has a 2 inch adjustment at best. Not 3 to 5.. And the scale, which most likely is faultable, isn't necessary. You just added 10 inches plus to my hitch, which means if your product fails, so does my trip. Blue oxe, over priced. Curt same technology yet a non chain assembly. Better for less money. This company hasn't even talked about sway control. There's no way their pivot point can capitalize on that. Give this Ford owner with a pulling machine, pulling a 35rlts grand design bumper pull, 3pull outs, 38 foot length, and I'll sell your product religiously for free if it works.
Morgan DOES NOT explain the mechanics of HOW the distribution hitch works. Annoying
wasted time here.
This is absolutely snake oil
if you need this you better learn how to load a trailer properly or get a REAL truck! these WDH are just a bandaid on a broken arm!
So… how does it work? What a waste of time.
I bought this and it was broken out of the box. Waste of money.
