Weight Distribution Diagram

Create a more stable ride for your tow vehicle and trailer with a weight distribution hitch. Adding spring bars to your towing system applies leverage, which transfers the load that is pushing down on the rear of your vehicle to all the axles on both your tow vehicle and your trailer, resulting in an even distribution of weight throughout. The result is a smooth, level ride, as well as the ability to tow the maximum capacity of your hitch.

Selecting a Weight Distribution System

The tongue weight rating is the most important factor in determining which size weight distribution system you should use. If the bars of the system you choose are rated too high for your setup, they will create a rigid ride, which can result in a bouncing trailer. If, on the other hand, the bars are not rated high enough, the system will be unable to properly distribute the weight, rendering it virtually useless.

To determine the proper weight rating for a weight distribution system, you must first determine your trailer's tongue weight. Then add to that the weight of the cargo behind the rear axle of your tow vehicle. These two measurements make up the tongue weight rating for a weight distribution system.

Features of the Equal-i-zer

Head Tilt Adjustment

Controlling head tilt with traditional washer method

The Equal-i-zer weight distribution system uses the traditional washer-style adjustment method to achieve the perfect tilt. Controlling the head tilt helps you to fine-tune the leverage on your entire system, making it easier to install and hook up the spring bars. To adjust the tilt, simply slide washers onto the spacer rivet and insert the rivet into the head assembly. To increase the angle, add a washer. To reduce the angle, remove a washer. Most setups take four to six washers to achieve the proper height. Once you get the desired tilt, insert the shank bolts to secure the head to the shank and then tighten it in place.

Construction of Spring Arms

The Equal-i-zer spring bars are not made of traditional spring steel. Rather, they are constructed of a chromium-molybdenum alloy steel. Chromoly steel has a high tensile strength for extreme durability. It also features excellent dexterity, which allows it to give as required and then return softly back to its original form. This pliability is important in minimizing trailer bounce while still ensuring that the weight of your rig is adequately distributed.

Fixed Sway Control Brackets

Installation of Sway-Control Brackets

The unique sway control brackets of the Equal-i-zer are easy to install and simple to use. They clamp onto your trailer frame and conveniently adjust to a position anywhere between 27 inches and 32 inches back from the coupler. These brackets provide the attachment points for the weight distribution spring bars. To position the spring bars during hookup, simply use the included snap-up lever to lift each bar into place on the L-shaped brackets. Then secure the bars in place with the included L-pins and clips.

Equal-i-zer Hitch 4-Point Sway Control

The Equal-i-zer weight distribution system works to stop trailer sway before it begins. This is achieved through the rotational friction that is present in the weight distribution hitch itself. Within the system head, the downward pressure that is placed on the hitch ball by the trailer is combatted by the upward pressure exerted by the spring bars that are mounted in the sockets. This upward force is placed on the spring bars on either side of the system, creating the rotational friction that, essentially, forces your trailer in line. This type of friction is responsible for two points - one on either side of the trailer - of the 4-Point Sway Control. To ensure that enough tension is present, make certain that the socket bolts in the head assembly are torqued to at least 45 foot-pounds.

Points within the Equal-i-zer system where upward and downward forces interact to create rotational friction

The other two points of sway control are created by the steel-on-steel friction that occurs when the spring bars slide within the L-brackets that are mounted on the trailer tongue. Most traditional weight distribution systems have spring bars that are suspended by chains. Although this ensures that the system is not so rigid as to create bounce in the trailer, it also allows a good deal of side-to-side play in the system. Letting the spring bars hang freely minimizes the rotational friction described earlier. It also eliminates your system's ability to create the type of direct friction that has been shown to be so effective in limiting trailer sway.

This direct friction that is applied to the spring bars in the Equal-i-zer system helps to stop sway once it has begun. The concept is similar to the way in which an add-on friction-sway-control device functions. When each spring bar moves forward or backward, or side to side, it rubs along the bracket, creating friction. The resistance created by this action limits the movement of the spring bar, thus preventing further side-to-side movement of the trailer.

Most add-on units feature some sort of friction material similar to that used in automotive brakes. But the Equal-i-zer uses direct steel-on-steel contact to create resistance. This is the same sort of friction that is used with locomotives that pull loaded railcars weighing tons. No additional materials are needed. The steel will outlast any of those other materials, providing an extremely durable, functional sway control system.

I have been using this EQ hitch towing my Bullet crossfire travel trailer with my F-150 for over a year now and it handles great. Tows smooth and without jerking or a rough ride. It took a few times to properly balance it and adjust it properly but what a major improvement from towing without it. I recommend this EQ hitch very much!!

Excellent! I have towed over 5000 miles in 2 years with this hitch now and it is still like new. What a great purchase.
MarkG - 01/24/2020


Ordered the Equal-I-zer weight dist hitch as a reaplacement for original W/D anti-sway hitch trailer dealer sold me (was getting quite a bit of sway). Relatively easy to install, instructions were very easy to follow, getting a torque wrench (430 ft-lbs) for the ball had been my only concern. Weight distribution was right the first time, truck and trailer sit nice and level. The trailer tracked very well and there was no sway when being passed by large tractor-trailers. Less noise than I expected after reading reviews when researching hitches. Very happy with the hitch and the GREAT service from etrailer. Highly recommend.


Was needing a weight distribution system for towing my 16' toy hauler and with Kats help from etrailer I couldn't be happier with this product. Trailer has a dry hitch weight of 950lb and 1100lb loaded. Set up took me an hour or so, but now I feel comfortable hooking and unhooking. Took it on a 100 mile trip a few weeks back in heavy rain with strong wind gust and handled great! Without it I didn't feel safe going 60mph on calm sunny day.


I purchased this hitch for a 9000lbs travel trailer with a 1001lbs tongue weight.
If your debating between a less expensive round bar and this setup, spend the money. This hitch is by far a better, easier, and safer setup.
I purchased this hitch to replace a Pro-series round bar with a friction sway control bar. The Equal-i-zer's 4 point sway control is big step up from a single point sway control system. The 1st drive felt secure and safe.

Install was easy, but time consuming for a 1st time installer. But worth it in the end.
Here's some pointers. 1. get the right tools, rent or barrow a the torque wrench to do the hitch ball 430ft/lbs, and shank bolts 320ft/lbs. The piece of mind that it's correct is worth it. 2. Plan for the afternoon, not a couple of hours. 1st setup is going to be close but your going to have to adjust it so plan on taking something apart. but setup is relatively easy, esp with the right tools. I had the trailer level the 1st go around to 2.5". So I had to move the head up one hole in the shank and then it was within 1". Distribution setup was still with in a proper setup, so I didn't have to make any further adjustments.
As far as the coupling and uncoupling the hitch. Using the tongue jack to release the tension is easy to do and quick. Esp. with an electric jack. I never liked the round bar with chain setup on my previous hitch.
High quality, easy install and setup, and seems to have great sway control.


I'm completely new to towing and the RV world. I searched high and low for a hitch that would make towing my 29 ft RV the least stressful as possible. I found this one but was still a little nervous about the whole experience.
Once it arrived in so many pieces I did get overwhelmed, but the videos and booklet provided truly helped a complete amateur put it together without issue.
And then once I drove with it, WOW!
I honestly forgot I was towing a 29ft RV at times. I had no issues turning and no issues handling. The weight distribution really did work. I even drove it in torrential downpour and had no issues with sway at all.
I am so impressed with this product and am so happy I found it. A true life saver for a beginner!!


I installed this hitch on my 2007 Toyota Tundra. I use to have the chain style. Big difference when getting next to rigs. This hitch is a much tighter tow. Glad I upgraded.


This hitch setup is worth every penny. Install was not painful and instructions were clear. After setup was finished I took her for a spin and I was amazed at the difference. The ride was smooth and no sway!!!! No more friction sway control for me!! I would recommend this to anyone who is in the market for a WD hitch.


The Staff at etrailer made the purchase simple and very helpful in picking the right tow package product. Installation instructions were sent when the product arrived. Great product n company!

Thank you so much Connie!


I have been hesitant to review this product as I have had several issues with it....not necessarily the product itself, but my use and application. To start out, I should have used a different drop down hitch. The one that came with the unit does not allow the ball to sit low enough for the trailer to sit level once everything is set. Get the right amount of weight transfer and the nose of the trailer sits high which has a negative impact on towing. Less weight transfer for a level trailer means to more truck nose lift, dangerous sway, dangerous driving. The worst part is that if I had been aware and asked to change the hitch, it might have only cost me 10-20 dollars. Now I need to purchase a new hitch with a bigger drop, which will cost me around 150 bucks. I do believe that this will make a big difference. As I have gotten the setup closer to correct, it does seem to work well. I do however feel that the teflon plastic slide pads for the L brackets would be a worthwhile investment as it is noisy when making slow speed turns, which can be dis-concerting

You realize that the friction where the spring bar slides in the L bracket is responsible for the sway control right? Reducing the friction would reduce the sway control of the unit... I am interested to try this product. I think what you are saying about getting the right set up for your individual rig is the most important thing.

We made a trip to the Pacific Northwest from Arkansas and I have to say, the hitch performed perfectly. Even in a high wind, which is common in Wyoming and the plain states there was no problem keeping a straight line going down the road. One time, when I wasn't paying attention and ran off onto the shoulder of the road, the trailer didn't sway at all but kept straight and allowed me to return to the road without incident. I would recommend this hitch to anyone pulling a trailer of any significant weight behind them. I have a 33 foot RV and pulling it with a 2015 Chevy Silverado 1500.

Its been over a year since I purchased my Equalizer hitch system and I am completely satisfied with it. Occasionally I have to spray some lubricant on the pivot points on the receiver end to keep the noise down but other than that It works as advertised and I would again rate it 5 stars.

Hitch works perfect. I first used it to pull my 24 ft car hauler with my Yukon XL and it worked flawlessly. I upgraded trucks to a 2500 Duramax and reset the hitch for it and all is perfect still.

Great quiet hitch!


Great product except for one thing. If you are going to sell this hitch either sell it with ball already attached or include the 1 7/8 thin wall socket with it. Could not find socket anywhere locally and finally had to dismantle Equilizer bar sockets which is no easy task , and then use regular socket that I already had, what a pain. Other than that great service and ultra fast shipping. I think I ordered it Tuesday night and had it Friday night. Great job.

Will repost once all is installed and try it out.

Best hitch on the market for anti sway and load equizling. Quick hook up, love it!

The Equalizer Weight Distribution System w/4 point sway control is as good as advertised. The installation took me approx 2.5 hrs and it was not difficult, just took a little time to make fine tuning adjustments to get the performance from the system that I wanted. The Equalizer System has removed an estimated 95% of the sway issue that I was having while pulling a 29 ft travel trailer with a mid-size Chevrolet Colorado pickup. Looking forward to getting out on the road and giving it a thorough testing, but so far it meets my expectations.

This hitch was a great investment!! It has made a huge difference in how my trailer handles in the Texas winds. I used to get white knuckled every time that I set out on a trip with my previous chain hitch and seldom ever felt comfortable in pulling the trailer at speeds in excess of 45 mile per hour. Now I can move along at normal Dallas freeway speeds in comfort. This hitch was a welcomed addition to my RV experience.
Jim H - 07/06/2018


12000 lbs. hitch was a great improvement over my previous bent bar hitch with chains. Trailer sway has decreased a lot. MY 35 foot trailer pulls straight except when it is windy. I am no longer bothered by passing vehicles. Was noisy until I added the nylon pads from equalizer. Much quite now.

Keep in mind that the jackets or pads will decrease the effectiveness of the sway control to a degree because they limit some of the metal-on-metal friction which provides the sway control.

Good product and great communication from eTrailer


This hitch has been great! No complaints and no regrets at all. It does a great job of anti-sway, which was my main reason for purchasing the Equalizer over other weight-distribution hitches. I did a bunch of research before purchasing this, and the majority of the reviews were very positive. This is also my sentiment in my experience of using it over the past year. You just need to make sure it is installed correctly and setup properly, otherwise your experience could be different. It's not difficult, just read the instructions and double check what you're doing. Once it's setup properly, you'll never have to touch it again.


Fantastic Hitch! etrailer had the best price by far, arrived within 4 days of placing the order in excellent condition with no shipping damage or missing parts. Mt RV Dealer did the original setup, but their installers apparently never watched a video on proper installation, as they took no before or after measurements of my truck wheel well height, never used a torque wrench, and placed the sway bracket assemblies at 27 inches from the ball when 32 inches (factory recommended distance) was easily available on the trailer. Many other install errors as well like incorrect number of spacer washers and incorrect L bracket mounting hole positions, all of which caused my 2016 Ford F-150 to squat while towing. Never assume the dealer service department knows what they are doing! Once home, I set the hitch up as instructed by Equal-i-zer without too much difficulty. This hitch now has my truck sitting level and tows like a dream with very little sway at all, and I tow a 35 foot travel trailer. Keep the hitch lubed as instructed, and use the optional sway bracket jackets and this hitch is fairly quiet. Well worth the money, no more white knuckles!!




I recently replaced my weight distribution and sway bar that had the chains for distribution and the brake style anti-sway with the Equalizer 1200. I also had purchased a scale to weigh tongue wt. I wanted to wait until I had some good miles on it before I reviewed. I tow a 33 1/2 ft toy hauler with a RAM 1500 eco-diesel and am pretty much maxed out on what I can safely pull. After weighing my rig at a truck stop and then checking my tongue wt, I called etrailer and got excellent confirmation on which set up to use. The 1200 worked like a dream. My wife actually let go of the dash board and commented on how much smoother and controlled the ride is. If you have any doubts as to the ability of these set ups, put them to rest. I couldn't be more pleased. The sway is all but eliminated and the ride has improved dramatically. On another note, I also found the 1200 cheaper but without the ball. I submitted the link as directed to and I was expecting them to reply with, 'this isn't the same'. Instead, they added $22 to the price I submitted to include the ball and then gave me their guaranteed price match. To me, this speaks volumes for their honesty and integrity. This is not my first purchase through them and I will not hesitate to use them again.


I received this hitch about a month ago and couldn't install right at first due to some issues I was having but I have finally got it installed and set up right. This is great! I will go on my maiden voyage Memorial weekend but I'm sure it is going to perform as expected. Excellent price that no one can touch. Instructions are easy to follow and detailed the way it should be. Time, was about as expected, so don't rush because you don't want to miss any steps.

Well I have owned this hitch for a year and it has worked flawlessly. In July we took our camper on a 2000 mile trip and we had no issues with the hitch at all. We were in all types of traffic through large and small cities, we didnt have any sway issues because the hitch, now broken in, works much better than I knew it would. I had installed the pads under the slide bars and use the grease to quieten it down when in all the turns I made during this trip. I dont believe there is a better hitch out there that can tame my 38 ft 9000lb Jayco than this Equalizer. Best money spent here. 11/7/17
Herman S - 11/07/2017


Product was easy to install, following instructions that came with. Video's online also helpful. It was recommended to use thin wall 1 7/8" socket to tighten the hitch ball nut, but was able to get a impact socket into the space. The trick is to turn the square weight distribution receiver's out to the side. ( ie...perpendicular to the hitch receiver. ) They come from factory at a 45 degree angle, turn them out to 90 degree's. Then the socket fits in to tighten the nut.

Great videos online from product on how to make sure your weight distribution is correct once installed on tow vehicle and trailer.


The weight distribution hitch I bought from is exactly what I thought I was buying and has been just fine. Far and away more important is how refreshing it is to buy from a company that goes to significant efforts to make sure their customers are happy with their purchase. Thank you I would be happy to do business with you in the future.

I am a frequent online buyer and I almost never do the requested reveiws. But this is one case where I will go on the record in support of this company. I have had a few transactions with them and the one time I had an issue it was quickly corrected. Handling, shipping and my receiving what I ordered was very quick and afterwards they reach out to make sure I got what I wanted. Sad to say, this kind of customer service is shocking!


Biggest Pros:
- Easy to install initially
(though I did have to buy a special socket, 1 7/8, to hook up the ball, so this could be a con too. A wrench won't work)
- It really does do a great job of stabilizing the trailer going do the road)

Biggest Cons:
- Weights around 100 lbs and has actually threw my back out trying to hook it up.
- Hard to connect stabilizing bars, as well

That said would not buy again or recommend, am currently looking for a better solution. The Doctor bills alone could cover a much more expensive unit. Not to mention the pain!!! Together these reasons are enough for me to NOT recommend!

NOTE: I am a 38 year old man that exercises and lifts weights at least 5 days a week, usually 7; my life revolves around the gym. I say this only so you believe me - This thing is heavy and awkward.



The installation process was fairly easy, but if you're planning on doing it yourself, keep in mind you'll need the 1 7/8" thin-walled socket (EQ70-00-4800), and most likely a 3/4 drive extension to clear the head, as well as a torque wrench that can read up to 420+ lb/ft. I wish etrailer would sell the extension like they do the socket, though - I lucked out and found one locally, but they only had one, and they were the only store I could find in 50 miles that had 3/4 drive extensions.

Hitching is a little more difficult than using a chain WD system because the arms are so hard to get into position, but not needing a separate anti-sway mechanism is great, and after dealing with a failure and warranty claim with a competitor's chain-based system, the quality, customer service, and warranty terms of the Equal-i-zer really set it apart.


Works great. We live in the mountain area of East Tennessee. I hit mountains no matter which way we travel. Been to Western New York to Central Florida. No problems.

  • Equalizer 4-Point Sway Control/WD Connected to Motorhome with Air Suspension
    Weight distribution like the Equal-i-zer kit part # Eq37120ET that you referenced will do a great job with your tow vehicle that has air brakes to improve handling, braking, and sway reduction. Since the GVWR of the trailer is 10k this system would be ideally rated and would work well.

  • How to Determine if Weight Distribution System is Set Up Properly On New Truck
    When installing a weight distribution system on a new vehicle you will want to basically run through the entire setup procedure so that you can make sure you have the correct amount of spring bar tension in the system. The goal with an Equalizer weight distribution system is to get the distance from the ground to the wheel well half way back to the unloaded height when compared to the height of the vehicle with trailer connected. So if the distance was 30 inches unloaded and then 28 inches...

In regards to the compatibility with your...

  • How To Prevent Trailer Sway While Towing a 2005 Fury Toy Hauler
    Yes, the Equal-i-zer Weight Distribution System part # EQ37120ET has the most innovative sway control on the market as it has four points of friction whereas most other systems only have two points of friction. Therefore, if any system were going to help cure your issue with trailer sway it would be the Equal-i-zer. The above is rated for up to 1,200 lbs of tongue weight which will be perfect if you are indeed right at around 1,000 lbs. This system is also one of the most durable on the...

  • Can You Reverse With the Equal-i-zer Weight Distribution System
    Generally speaking, all weight distribution systems whether they have sway control or not are going to restrict your ability to reverse the trailer at too sharp an angle. There are some systems that allow for more of an angle than others but the Equal-i-zer Weight Distribution System part # EQ37120ET is a good in between option. That said, if you do need to reverse at a sharp angle all you need to do is remove the L-pin from the frame brackets and then slide off the spring bar ends. The...

  • Is Weight Distribution System Longer than Standard Ball Mount
    When compared to a standard ball mount weight distribution systems like the Equal-i-zer part # EQ37120ET do have the hitch balls out a bit further. The ball center will be about 11 inches from the hitch pin hole depending on the angle the head of the system is set at. A standard ball mount will have this distance between 6 and 9 inches typically.

  • Weight Distribution Head Pulls Away From Shank When Setting Up Equal-i-zer 12K System
    I contacted Equal-i-zer and the most common reason that the weight distribution head from the Equal-i-zer Weight Distribution systems like part # EQ37120ET would pull away from the shank is the angle set bolt on the bottom of the head is too tight when you torque the bolts. If it is too tight when you try to torque the bolts the head will pull away from the shank. You want to angle set bolt to be barely snug before you torque the bolts. The angle set bolt needs to be last bolt that is tightened...

  • Can a Weight Distribution System Be Used on a Motorhome with Airbags
    Yes, you can use a weight distribution system on your motorhome while towing a trailer. Since you have airbags, you will want to couple the trailer and then let the airbags adjust. Once the airbags adjust, you can then set the spring bars on the weight distribution system to take the remaining sag out of the equation. In order to select the correct weight distribution system you will need to determine your total tongue weight (TTW) which is the loaded ready to tow tongue weight of the...

  • Why Is Trailer GVWR Higher Than Combined Capacity of its Axles
    You are exactly right when you mentioned the tongue weight of a trailer being accounted for when determining its overall capacity. It is not uncommon for trailer manufacturers to list a trailer's GVWR to be a bit higher than the combined capacity of its axles. This is because a portion of the loaded weight will be tongue weight, which will be applied to the tow vehicle and won't be directly on the trailer axles. A trailer's tongue weight is typically around 10 to 15 percent of its total...

  • Does a Weight Distribution System Decrease Tongue Weight
    No, a weight distribution system will not decrease the tongue weight capacity of a vehicle or trailer hitch. It will in some cases actually increase both the tongue weight capacity and gross trailer weight capacity of the vehicle/hitch. If this is the case then there will be a figure for this new rating either on the hitch itself or in the vehicle's owner's manual. The best weight distribution system we offer in my opinion is the Equal-i-zer Weight Distribution System. The reason I consider...

  • Best Weight Distribution System for a 10,000 lb Travel Trailer
    For starters, if the gross combined weight rating (GCWR) is 16,200 lbs and the gross vehicle weight rating (GVWR) is 7,000 lbs then your towing capacity is 9,200 lbs, not 10,800 lbs. The correct GCWR and GVWR figures will be found on the driver's door jamb. However, the towing capacity of the vehicle only needs to be rated for the gross trailer weight (GTW). Regardless, if the trailer has a hitch weight of 1,000 lbs I recommend using the Equal-i-zer Weight Distribution System part # EQ37120ET...

  • Can Equal-i-zer Spring Bars be Removed to Make Sharp Turn
    Yes, you can remove the spring bars of your Equal-i-zer Weight Distribution System # EQ37120ET in order to make a turn to back into your driveway. When you do that the system essentially just becomes a ball mount and to make a tight turn it is often necessary to remove the spring bars.

  • Does Tongue Weight of Trailer Need to be Measured After Install of Weight Distribution
    There really isn't a need to try to determine tongue weight of a trailer after installing and setting up a weight distribution system. You want to know the tongue weight so that you can pick out the correct rated system, but beyond that you do not need to measure it again, nor is there a great way to do so.

  • Does Tongue Weight Need to be Factored After Weight Distribution System is Installed and Setup
    If you have a properly rated and setup weight distribution system installed on your towing setup like you mentioned and you are under the towing capacity for the vehicle you do not need to worry about the tongue weight figure. Also, a tongue weight scale is not compatible with any of the systems we have and would not be accurate either due to the spring bar tension.

  • Solution for Bucking When Towing with Equal-i-zer Weight Distribution System
    The bucking you're experiencing on the highway could simply be due to the Equal-i-zer Weight Distribution System # EQ37120ET being a bit too tight or maybe over-rated for your setup. If the bucking is more of a severe jerking type action (like driving fast over a speed bump and hitting those factory bump stops on the truck) then this is most likely the case. Try removing a washer or two from the head to see if this helps. It could also be that the system is rated too high for your total...
