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 29 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.

Steel-on-steel friction works to prevent and correct trailer sway in this unique weight distribution system. Sway control brackets ensure that your trailer stays in line with your tow vehicle. 2" Hitch ball and adjustable shank included.


Towing 3400 lbs hybrid camper with ford flex (tow rating 4500). Makes a world of difference. Car downshifts less, rides more level and experiences very little sway. Wasn't cheap, but was worth the money as an improvement over towing without distribution hitch.


The Equilizer hitch has made towing much, much better for a short, single axle travel trailer. There is zero sway. The only issue we've had is that the brackets mounted to the trailer frame tend to slide or tilt occasionally, so periodic adjustment is needed. The hitch isn't as noisy as I was expecting. Love the easy setup and tear down, too.


I ordered a weight distribution system for my camper. I needed rush delivery. The folks on the phone were great and I received the order on time and it worked out great.


Love the equalizer Hitch. Even more so I love this site. Awesome prices and I received my Hitch three days before I thought it would come.


Great product. Pulled a rockwood A212 with a Nissan Murano made a world of a difference. Good Distribution of the weight.


Excellent customer service and follow up thru the the entire process. Found what we needed when no one else could on etrailer


Preston took a lot of time researching the right product for my application.

He was patient while I got him the measurements.

Thanks much.


We’ve only used the hitch once but it’s been easy to use. Service was great! Would definitely buy again.


Love it! Highly recommend it!



Great product, recommended for any towing close to maximum capacity. Excellent sway control





Well made, heavy duty, easy to assemble, and install. Only one issue, the sockets that the sway bars go into are virtually immovable. I had to loosen the bolts and beat on them with a rubber mallet to get them to move (they are supposed to move freely). I contacted the manufacturer directly via their customer service, and was informed that there is a 4 trip break-in period and that “eventually” the sockets will move easier. This disclaimer should be noted in the advertisement for this hitch.


First 400 mile tow today, 50% of that way loaded. Performed flawlessly, although I don't think I have it set up 100% yet. Finding a perfectly level spot in MA is an exercise in futility. I did the best I could with the trailer level in my shop on concrete, but the truck hanging out and nose down and to the left a bit. I think I need more tension. Rides real stiff compared to the Reese SC system I was forced to retire early due to parts being NLA (lost a torsion bar on a recent tow - don't know if it broke, or just slipped out - either way, I'm DONE with Reese!). As of right now, the bars feel like they have unequal tension, too. When unloaded, the left bar sits tight to the L-bracket, while the right bar is easily lifted by hand. Could be that my receiver is worn out - she's got some miles on her. Don't think anything is bent anywhere, but who knows. Anyway, these parts are HEAVY, strong, American metal - I have no doubt this thing will outlast that Reese system I had. Now to put in some work to try and get the ride quality back like the old system.


This is Amazing! Works really well! Gotta grease it a lot at all the moving parts before you roll with it. If you don’t it makes horrible noises. That’s my only issue with it. And if you could get more tongue weight too! That would be Awesome! But can’t have your cake and eat it too! Thanks


I rate this product "good" to alert potential users to an issue I face during installation of this Equal-i-zer hitch.

As I purchased this hitch, a 2 and 15/16" ball with a 1.25" shank stud and its nut were included. That nut requires a special 1 and 7/8" thin walled socket that slips down into a cavity where the shank stud protrudes and the nut screws on. The instructions state that socket is available at Equal-i-zer dealers. Such a socket WAS NOT AVAILABLE at any automotive parts store, car dealership, nor agricultural supply hardware I contacted in the small California town I was in. The nearest Equalizer dealer to me was over 100 miles distant, and I had planned to leave the day I began installation of the hitch. The instructions also state that a shim can be used if a 2 and 15/16" ball with a 1" shank stud and nut are used. That is the ball I already had on my truck and I was fortunate to find a properly sized shim at an agricultural supply hardware that I cut to length and used in my installation. I still needed a large socket and extension to tighten the nut because the nut was deeply recessed in the cavity. The box end wrench I normally used on the nut was of no avail; however, an automotive repair shop had such a socket and loaned it to me to complete the installation of the hitch. IF you are going to undertake the installation of this hitch yourself, then be aware of the need for either the special Equal-i-zer specified socket for the ball included, OR a 1.25" to 1" shim and a deep well socket for the smaller 1" shank stud and nut such as I used. Contact customer service at Equal-i-zer if you have questions in this regard BEFORE you purchase.

Having alerted you to the installation issue I faced, I now rate the product itself as EXCELLENT in performing the job it is intended to do when towing. Once I had the hitch installed, the instructions for making adjustments so it will perform as intended are clear. Along with the hitch I purchased a Sherline trailer tongue scale and that is an accessory I highly recommend.

I was towing a 2-axle car trailer loaded with a vehicle for a total tow load of 5500 lbs.
Using the tongue scale I adjusted my load so 10% was on the tongue. I was towing cross-country from California to Michigan with a 2010 Tacoma 4 x 4 rated with a 6500 lb towing capacity. I towed at 55-60 mph and had one incident that required immediate, heavy braking and the truck and trailer stopped perfectly, as if the trailer had no been there. So keep in mind, my rating of GOOD was to draw your attention to the installation issue I faced. The PEFORMANCE of the hitch was EXCELLENT.


I received this hitch a few short days after placing my order and as soon as it arrived I unpackaged it to admire the contents. Everything was intact and ready to assemble, just as expected. I also ordered the special thin walled socket, which I am glad I did since my mechanic friend that did my torquing didn't have a socket that would work for this hitch ball. I know it is expensive but I wanted everything done right.

I installed the hitch and set it up following the directions in the manual, and everything turned out perfectly. I think from start to finish it took the wife and I less than an hour and a half. Easy, and according to my measurements and a visual everything looked perfect. None of this is rocket science, and the installation is truly easy.

Well, time to try it out, and what great timing, we left Saturday morning in a 40 MPH headwind for 20 miles, and then another 25 miles with the wind quartering at us on a busy highway. This hitch worked flawlessly! I was tickled with the whole ordeal, and today coming back with no wind at all it wasn't much different than the day we had the wind. You know what wind means, right? WINDY IN ND. Yep, we get our share. This hitch served us very well, and I am extremely pleased with my purchase and the ease of installation and set up. I would order it again in a heartbeat.

My tow vehicle:

2018 GMC Sierra 1500 with max trailer tow package. 6.2 L with 8 speed transmission.

My travel trailer:

2016 Jayco Octane SL, weighs in loaded at 6100 lbs with a hitch weight of 910 lbs.


Just received and put together my Equalizer hitch but not set up or used with our new travel trailer yet. The quality of the parts are amazing. I have used other weight equalizing hitches and have 5th wheel hitch systems. This system is heavy duty and a pleasure to put together. Etrailer did a great job on the website describing, illustrating and proving support to make my decision so easy. Thanks Etrailer. Going to pick up new travel trailer today with new hitch 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!!


Although it seemed expensive at the time, it has turned out to be well worth the cost. Towing with vehicles without a solid rear axle leads to aggressive tire wear, and this makes that aggressive tire wear go away. That means, for me, it's saving me from buying a new set of tires every year for the tow vehicle, so it's more than paid for itself.

I didn't buy it for the sway control, but it makes a big difference. Well worth it if you have trailer that can't be loaded perfectly, like a contractor trailer. The only downside is that it takes about twice as long to get it hooked up to the tow vehicle.


Great hitch system. Easy directions to mount and set up for my truck (F150) and Grand Design Imagine travel trailer. Hook up at camp site is much easier compared to my chain and bar system. New set up handles sway and is very stable when trucks and cars pass.


One of the most important parts of this system is the Ball, so the customer should be asked for their Ball size and that should be what they send with the system, or they should specify you need to purchase the correct ball size with the system. Instead, they sent a 2" ball which I missed in the description of what comes with it, that's my fault. Now I have to search around for the correct Ball to fit my trailer and the system, and I'm stuck with a worthless 2" ball with a large shank that doesn't fit 90% of all ball shanks. I emailed Trailer about this and their reply was it comes with a 2" ball... not helpful.


Product is well made and sturdy. Installation instructions were simple and easy to follow. Took about 2 hours from start to finish to install. The problems it solved for me were the truck sagging in the rear when my car hauler is coupled. Now the truck is level along with the trailer. Also when semi's pass by the entire set up is steady. No shaking or swerving. Wish I had put this on sooner. Very pleased.


First I want to say I think this is a really good weight distribution and sway control system. It is not perfect, but it is very effective and I'm not certain there is a perfect system on the market.

Pros- Our travel trailer rides noticeably better with this system. Our half ton bounces less and the sway is noticeably reduced vs. the old chain/tension bar WD system we had. It's easier to take the tension bars on and off.

Cons- Setting up for proper height and weight distribution is cumbersome. It takes a fair amount of trial and error (unless you get lucky the first time) to get this correct. It's worth the effort, but is a bit of work.

Tips- Keep the hitch/load bars/socket properly lubricated. Not doing so can cause the trailer to tow at an offset after making a sharp turn.

Take your time setting up the hitch. As mentioned it's a lot of work but absolutely worth it.

Research the tools you need to set this up. You may not have the correct sockets and 300 ft-lb torque wrench needed for installation.

This will not magically turn your 1/2 ton into a 3/4 ton. It might make your 1/2 ton haul your rig better, but a 3/4 ton it will not be.

Additional info- we have hauled our 30ft travel trailer (6800lb dry weight, approximately 7500-8000lbs loaded) with a 2021 Silverado 1500 (crew cab, 5.3L, rated to haul 9500lbs) and with a 2000 Ford Excursion (V10 4x4, rated for 10000lbs). Even with the Equal-i-zer the camper can push and sway with the Silverado 1500, especially over 60mph (we keep it at 65mph or below) in windy/interstate conditions. With the Excursion and the Equal-i-zer installed the only noticeable difference between driving the truck with and without the camper is the truck is slower with the camper hooked up- bouncing, pushing, swaying are really not noticed.


The equalizer hitch is a game changer i use to have to install seperate sway control with my hitch with chains now its all in one and works at eliminating sway all in one unit very happy

  • Can You Back Up and Turn With Weight Distribution System Installed on Trailer
    With weight distribution systems like the Equal-I-Zer # EQ37040ET that you referenced you can back up and turn slightly but you basically can't jackknife the trailer as it will brake things. If you can imagine how tight of a turn you can get into while going forward that would be the same sharpness you would be limited too when backing up. If for some reason you have to go super sharp you would need to disconnect the sway bars and you can go as tight as you want.

  • Recommended Weight Distribution System For 2003 Nissan Xterra With Small Tent Trailer
    For your 2003 Nissan Xterra and Forest River Tent Trailer, I recommend the Equal-i-zer Weight Distribution System part # EQ37060ET which is rated for up to 600 lbs. The 400 lb system part # EQ37040ET would not be a good choice as this will be at the very end of your capacity which does not leave room for error and with the above you can add weight over time if needed. I always recommend going with the next size up system from what you think that you need.

  • Best Weight Distribution System for a Keystone Outback 31
    The best weight distribution system we carry is the Equal-i-zer Weight Distribution System.

  • What is Best Way to Prevent Suspension Sag with 2016 Ford F-150 Towing Travel Trailer
    Hey Orlando, it's interesting that the dealer recommended against a weight distribution system because that would actually be your best solution to level your truck when towing. A suspension enhancement solution for the truck like an air bag setup would provide additional support to level the truck but that's as far as the benefits really go. A WDH system is going to actually put some of that tongue weight up on the front axle of the truck which greatly helps braking and handling so it's...

  • Recommended Weight Distribution System for a Jayco Jay Feather Travel Trailer
    Weight distribution systems are selected based off of tongue weight which is typically between 10% - 15% of your trailer's total weight. Since you're not hauling water your trailer's tongue weight should be between 300 lbs - 400 lbs depending on what's mounted on your tongue. With as light of a trailer as you have their aren't many options for that low of a tongue weight which is probably what has caused your confusion. With all of this in mind, I recommend the Equal-i-zer Weight Distribution...

    I took a look online, the Curt Trailer Hitch item # C13105 you have on your Sienna is rated to be used with a weight distribution system.

  • Could Husky Weight Distribution System HT32216 Work on Trailer that Weighs 3,300 to 3,500 lbs
    If your tongue weight ended up being above 400 lbs and below 600 lbs the Husky Weight Distribution System part # HT32216 would be a great option. If instead it was lower than 400 the Equalizer part # EQ37040ET that you also referenced would be a great option.
