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.

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. 402238

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.

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. 275437

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. 305707

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. 314559

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

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. 305090

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 57823

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.
-- comment by: Donny - 02/01/2014


The nylon jackets may very well reduce the sway control ability of the unit. For some applications, the reduction is sway control is not problematic and sometimes the noise is just too much. It is up to the user as to what they need more, but the jackets are available for those that want to get rid of some of the noise.

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. 386771

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. 472980

The equalizer hitch has made towing my horse trailer much more secure. I hardly feel the trailer and it does not sway at all. My truck is now even, I didn't realize how the trailer impacted steering and with the new equalizer hitch, steering is better. I am a 60+ year old woman and I can set up the hitch and unhitch on my own. The instructional video is very helpful. 882618

- EQ37120ET

I would highly recommend this system if you have any sway problems. I tried distributing weight in the trailer, stiffer 10 ply tires, and a home made anti sway bar on the trailer axle. This things helped a little bit but the Equal-i-zer planted that trailer right behind the truck. Even when I swerve so miss a pot hole at 70 mph it centers itself behind the truck. The instructions were some of the most thorough I've seen. 869178

- EQ37120ET

Hitch does very good job of weight distribution and sway control. Other than getting grease on you it is easy to use and hook up. My wife has it mastered and she generally avoids mechanical stuff. Only reason for 4 vs 5 star is the messiness of the grease. You need to keep ball, hitch plate and arm supports lightly greased. Make sure to not bump into it or you will be cleaning. 859432

- EQ37120ET

Nice product, had to get used to loud squeak when making sharp turns or backing into campsite, a little oil takes care of the squeaks temporarily, but it's very tolerable once you get used to it. Again a very nice product I would recommend it to anyone who asked. 848248

Hitch came in quickly and the price is very competitive. Etrailer has been a consistent supplier of us in the midst of this pandemic. 829441

- EQ37120ET

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. 819865

The hitch worked First on a 2020 Forest River Rockwood, traded for a 2018. Jayco White Hawk.In both cases the hitch performed well. 793083

- EQ37120ET

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.

I could not be happier with this hitch. This is my second one as I upgraded my Airstream to a GT27FBT. I considered the more expensive and highly regarded options, but the ease of use and overall experience with my first hitch kept me with Equal-i-zer. Price, availability, and delivery from etrailer was perfect. Highly recommended all 'round. 745173

The weight distribution hitch I bought from Etrailer.com 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 etrailer.com. 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! 705819

I bought my trailer used and it came with hitch that was underrated for the load and did not have sway control. This hitch solved both of these problems. I was going to take it to a dealer to have it installed, but after reading the directions decided to do it myself. I discovered t was easy to install - although it takes a bit of time to get it right - and you want to get it right. The instructions were clear and easy to follow. I can now tow my trailer in confidence. 673800

    You want your trailer's tongue weight to fall right into the middle of the tongue weight range of the weight distribution system you go with.

    A WD system is recommended when the trailer weighs more than half of the weight of the tow vehicle. If this is the case for your trailer and your 2012 Ford F-250 then I do recommend using a WD system as it will distribute the Tongue Weight (TW) of your trailer among all of the axles.

    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.

    When choosing the right weight distribution system, the most important factor to consider is the total tongue weight of your setup. The total tongue weight is the loaded tongue weight of your trailer along with any added weight behind the rear axle of your tow vehicle. Typically the tongue weight will be around 10-15% of the trailer's total weight. So we can estimate the loaded tongue weight of your trailer to be around 650-975 pounds.

This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached a help article on determining tongue weight for you to check out as well. You will want the loaded tongue weight of your setup to fall right in the middle of the tongue weight range of the system you use. Once you know your tongue weight...

  • How to Gain Clearance for Turns Using Equal-i-zer Weight Distribution System
    I verified with Equal-I-zer that adding some washers to raise the hitch ball of your weight distribution system # EQ37120ET is perfectly fine. A few things to keep in mind: If you use a different hitch ball make sure the threads do not hang below the cavity of the hitch head. Also, make sure the top of the hitch ball isn't more than 1 inch higher than the coupler, and finally make sure you torque the ball down to spec.

  • Comparing Equal-i-zer and Curt TruTrack Weight Distribution Systems
    Between the two kits you mentioned the Equal-i-zer part # EQ37120ET is the best choice. This is the highest quality option out there for a weight distribution system and is what Curt tried to emulate with their TruTrack part # C17501. The Curt kit is relatively newer and while not a bad system by any means does not have the decades long tried and true reliability that the Equal-i-zer kits have. It will perform the best and last the longest. Plus it comes with the 2-5/16 inch ball you want...

  • Recommended Equal-i-zer Weight Distribution System for Car Hauler with 800-1,100 Pound Tongue Weight
    If the loaded tongue weight on your car hauler varies between around 800 pounds to 1,100 pounds, I recommend going with the Equal-i-zer Weight Distribution System # EQ37120ET. This particular system features a tongue weight capacity of 800 to 1,200 pounds, so while it might be just a tad over-rated when towing on the lighter end of your range, it will still work nicely to provide you with the benefits of a system like this. Then when you are on the higher end, you will still sit comfortably...

  • Recommended Weight Distribution System for 27 Foot Airstream Trailer
    Based on the 27 foot length you mentioned it sounds like you have the Airstream Flying Cloud 27FB or 27FB Twin model, both of which have a maximum loaded trailer weight of 7,600 pounds. If this is correct I highly recommend the Equal-i-zer Weight Distribution System # EQ37120ET, which features integrated 4-Point Sway Control to drastically reduce any side-to-side movement during travel and simple clamp-on brackets that eliminate the need for any drilling into the trailer frame. It includes...

  • Comparing Reese Strait-Line and Equal-I-zer Weight Distribution Systems
    We sell more Reese dual-cam (Strait-Line) weight distribution systems than Equal-I-zer systems. But we have also carried Reese products since etrailer began and haven't had Equal-I-zer as long. The thing about Equal-I-zer is that they have brand recognition. People know who and what Equal-I-zer is which is why they are so popular. Their systems do work but like any friction type of sway control system they make a lot of noise and components can wear out faster than non-friction systems....

  • Will Over-Rated Weight Distribution System Cause Harsher Ride
    The Equal-i-zer Weight Distribution System # EQ37120ET referenced in your question has a tongue weight capacity range of 800 to 1,200 pounds. If your tongue weight remains within this range, this particular model will still be a good system for your setup. Keep in mind that your total tongue weight will also include any added weight coming from behind the rear axle of your tow vehicle, which will likely put the tongue weight of your trailer into this system's capacity range. If your...

  • Choosing Weight Distribution System for 8-Inch-Tall Trailer Frame
    The standard spring bar brackets in the Equal-i-zer 4-Point Weight Distribution Systems # EQ37140ET and # EQ37120ET will fit trailer frames up to 6-inches in height as you noted. There is no alternate part or adapter to allow these systems to be fitted on an 8-inch-tall trailer frame. For a tall trailer frame like yours the best weight distribution/sway prevention systems will be those that use bolt-on brackets and round bars that will provide better turning clearance at the nose of...

  • Recommendation For Equalizer Hitch For Towing 2017 Jayco 260 With 2018 Ram 2500
    To get the right Equal-i-zer Weight Distribution (WD) system for your towing setup, you need to know your actual Tongue Weight (TW) when fully loaded and ready to tow. You will also need to include any weight from behind the rear axle of your 2018 Ram 2500. To make this easier, I recommend using something like the Sherline Trailer Tongue Weight Scale, Item # 5780. As you determine this weight, keep in mind that the TW is 10% to 15% of the total loaded weight of your trailer.  After you...

  • Weight Distribution for Dump Trailer with 8 Inch Tall I-Beam Frame
    I do have a great option for you but a Reese system is not going to be the best choice in this case. You will need to box the trailer frame where the weight distribution brackets will go by having steel plates welded on. What you can use is an Equal-I-zer system, # EQ37120ET as an example, and then add 2 outer link plates, # EQ90-02-5378, sold in quantities of 1, and 2 inner link plates, # EQ90-02-5208, also sold in quantities of 1. That would allow you to use the system on an 8 inch...

  • Does Weight Distribution Hitch Stop Persistent Trailer Sway
    Weight distribution systems can help greatly with sway from passing semi trucks and high winds, but if you are getting a persistent sway all the time on the highway the issue is actually the loading of your trailer. You need to move the weight of your cargo further forward in the trailer so that you can get it to be around 10-15 percent of the total trailer weight. That's the only way really to prevent persistent sway. Also make sure your trailer is sitting as level as possible. The...

  • 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...

  • Recommended Equal-I-zer Weight Distribution Hitch for Ice Castle Fish House Trailer
    For your Ice Castle Fish House, the weight of the unit will determine what Equal-I-zer system will work best. A weight distribution system is based on the total tongue weight of the loaded trailer along with any cargo weight behind the rear axle of the tow vehicle. Because these trailers are fairly good sized, I'll give you a recommendation for a larger system. You want that total tongue weight to fall in the middle of the range of the system for best results. For a total tongue weight...

  • Can a Weight Distribution System Be Used with a Pintle Hitch
    You cannot use a weight distribution system with a pintle hitch. You would need to remove the pintle hitch you have now in order to use a weight distribution system. Once you do this, I recommend using the Equal-i-zer Weight Distribution System which has 4-point sway control that will be more more effective at managing trailer sway than most other systems. In order to choose the correct system you will need to know the total tongue weight (TTW) of your towing setup which is composed...

  • Easy to Use Weight Distribution System for a First Timer and 5,200 Pound Trailer
    To choose a weight distribution system you will need to go by the total tongue weight of the set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that the weight of anything loaded behind the rear axle of the tow vehicle. A trailer weighing 5,200 pounds would have a tongue weight in the neighborhood of 520 to 780 pounds (10 to 15 percent of the gross trailer weight). There are several systems that will work with this range. But...

  • How to Choose Correct Equal-i-zer Weight Distribution System
    The ideal situation for selection of a weight distribution/sway control system is that your fully-loaded trailer's measured tongue weight (TW) falls right near the middle of its operating range. The weight of any cargo behind the rear axle of the tow vehicle, which will act just like trailer TW, should also be figured into the TW calculation. For a total effective TW of 1000-lbs you will want a system such as the Equal-i-zer 4-Point # EQ37120ET that works over a TW range of 800 to 1200-lbs. If...

  • Tight Turning Ability with Weight Distribution System Installed
    When using a weight distribution system you will have nearly the same turning ability as you would without a weight distribution system in most cases. The difference is only slight when using a system like the Equal-i-zer # EQ37120ET where other systems may have further restrictions. This system will have just a slightly wider base but you can still make U-turns as needed. Some systems do not allow backing, but those systems are only the ones with the friction bar and it is due to...
