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.



by:

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.



by:

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.



by:

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.



by:

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!!



by:

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!



by:

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.



by:

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.



by:

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!



by:

This has been the second hitch I’ve ordered that didn’t come with the hitch ball when it says it does. Not sure if the description is inaccurate or if something has happened in transit both times (both times the box came damaged with a hole in it) , but I was able to order the ball separately and I love the hitch which is why I give the product 5 stars. I just hope the company sees this and figures out a way to prevent this from happening in the future.



by:

I love the stability of the Equal-i-zer 4-point sway control system. 15,000 miles and my tow vehicle and travel trailer have an "excellent relationship".



by:

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

Donny

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.

Patrick B.

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.


by:

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.



by:

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.



by:

Heavy duty hitch, very good quality, easy set up. Did a lot of research, and I'm glad I chose this hitch. Thanks etrailer.com

Joe

1/25/2020

After using this hitch for a year now, Im still glad I chose it. Its a heavy duty hitch, and heavy to handle, but worth every penny. It makes towing our travel trailer a breeze.



by:

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.

by:

All good with this hitch! We have pulled in high cross wind without much noticeable sway. Our truck and the trailer are level. After I learned the trick of raising the tongue a little above horizontal, I can install and remove the arms without using the cheater bar. I had to adjust the hitch after I traded trucks but it was a simple thing and took very little time. We've had people stop to look at it because they were tired of using the hitches with chain adjustment. Couldn't be happier. The support from etrailer staff is great.



by:

Ordered Equalizer hitch assembly on line. Best price and free shipping. Weighed over 100lbs! Got to my house as stated in 3 days! I use them all time!



by:

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!



by:

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.



by:

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



by:

Hadn't had a chance to use on road yet, but look like a very high quality product. Installation was very easy! Only took a couple hours to get installed and adjustments made. Watching video on etrailer.com will help, but included instructions are also pretty easy to follow. Shipping was extremely fast! Ordered on a Wednesday and it was at my door in south Georgia by 1:00 pm on Friday.

Don H.

4/24/2018

Very pleased with this hitch system after 1 yr of use. Did have to make one change to it, but that was not due to product defect. Originally ordered it with a 2 shank and later purchased a truck with 2.5 receiver. Tried using an adapter sleeve, but did not like the excess play with the sleeve. Felt more sway when towing. Was also a hassle to get 3 sets of holes to line up for hitch pin! Purchased a new 2.5 shank and all is good again!!!



by:

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.



by:

I cannot rave enough about this set up. I tow about a 10K trailer (RV when fully loaded) with a Ford F150 (yes an F150... but it was built for towing heavy and in fact, is actually rated better than my F250 Super Duty to tow heavy).

But it is working hard, no doubt and with this hitch I really cannot tell the trailer is there. In my humble opinion, best on the market, even tows better than my goose neck did.

I have put the same set up on my 4 horse trailer and will do so for my car hauler soon.



by:

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.

  • How to Adjust Weight Distribution Hitch to Reduce Truck/Trailer Porpoising
    Weight distribution spring bar tension can be increased by tilting the head toward the trailer so that the ends of the spring bars are closer to the ground. Once connected to the lift brackets this increased angle translates into more tension, which shifts more trailer tongue weight (TW) forward onto the tow vehicle's front axle. This is usually the best fix for a porpoising travel trailer. I also recommend checking your trailer's actual fully-loaded TW, with all gear and supplies in place,...

  • Recommended Weight Distribution System for a 2019 Forest River Grey Wolf 29TE
    For a 2019 Forest River Grey Wolf 29TE, I recommend the 2019 Forest River Grey Wolf 29TE part # EQ37120ET which is largely considered to be one of the best weight distribution systems on the market. The reason that the Equal-i-zer is the best is because it has a four point sway control system that works extremely well and it is the only system with a forged head which means it is very durable. It also comes with everything that you need and it will not require any drilling into the frame.

  • Weight Distribution System for Audi Allroad
    Your trailer hitch receiver may or may not be rated for weight distribution. If you let me know your model year I can help with specifics. If your trailer hitch receiver is rated for weight distribution, normally the tongue weight is increased and you'd need to fall within those parameters. There should be a part number or even a specific tongue weight listed on your trailer hitch for use with weight distribution. If you just find the part number plug it into a search and see if you...

  • Does Length Matter When Towing with a Short Wheelbase Vehicle
    The biggest factor to consider when towing a long trailer with a short wheel base tow vehicle is trailer sway. There is no standard ratio for wheelbase to trailer length, but the general rule is a longer trailer and a shorter wheelbase will increase the severity of trailer sway. For your towing setup, I strongly recommend considering a weight distribution system with integrated sway control like the Equal-I-zer systems because they will be your best solution for fighting trailer sway....

  • How To Upgrade an Equal-i-zer 1,000 Lb Weight Distribution System to 1,200 Lbs
    In order to upgrade your Equal-i-zer 1,000 Lb Weight Distribution System part # EQ37100ET to the Equal-i-zer 1,200 Lb Weight Distribution System part # EQ37120ET you will need both the Replacement Head for Equal-i-zer Weight Distribution Systems part # EQ90-02-1200 and the Replacement Spring Bars for Equal-i-zer Weight Distribution Systems part # EQ90-01-1299. The heads are different which is why you just can't swap out the spring bars. The lower rated 600-1,000 lb systems all use the same...

  • How to Determine Which Weight Distribution System Will Be Needed for Towing a Travel Trailer
    When trying to decide on a proper weight distribution (WD) system for your towing rig, you will need to know the total tongue weight (TTW) of your set-up. The total tongue weight will be a fully loaded ready to tow trailer, plus any weight located behind the rear axle of your tow vehicle. You want to use a system where your total tongue weight will fall in between the WD system's tongue weight range. I have attached an article that will explain how to find the TTW of your towing rig. Once...

  • Recommended Weight Distribution Hitch for a 13,200 Pound Toy Hauler
    From the weight you listed, I think the Eqaul-i-zer # EQ64FR may be a bit over rated for your trailer. What you really want to do is shoot for as close to the middle of the systems capacity as possible. So with that being said, I recommend going with the Curt TruTrack # C17501. This will have a minimum tongue weight of 1,000 pounds and a maximum tongue weight of 1,500 pounds, putting you in a better place. As to the noise. All weight distribution systems are going to make a "grinding"...

  • Upgraded Shank To Use Equal-i-zer Weight Distribution System On a 2017 Chevy Silverado 2500
    I have exactly what you need for your Equal-i-zer Weight Distribution System part # EQ37120ET, the Equal-i-zer Weight Distribution Shank part # EQ90-02-4700. This shank has the same rise/drop as the one that came with the above system but has the larger 2-1/2" shank that will fit securely inside the receiver tube opening on your 2017 Chevy Silverado 2500. The receiver tube opening on your 2017 Chevy Silverado 2500 is 2-1/2", not 2-3/4". This will reduce rattle and play tenfold when compared...

  • Equalizer Weight Distribution System Recommendation for Trailer with 1,100 lbs Tongue Weight
    Ideally you want your loaded tongue weight to fall right in the middle of the tongue weight range for the weight distribution system. The 1,200 lb tongue weight Equalizer system part # EQ37120ET that you referenced has a range of 800- 1,200 lbs so you'd be higher than ideal if your tongue weight is 1,100 lbs. The part # EQ37140ET would be better if that's the case as it has a range of 1,000 lbs to 1,400 lbs tongue weight.

  • Selecting Correct Weight Distribution Shank for Equal-i-zer System on New Travel Trailer
    The adjustable shank that is included with the Equal-i-zer Weight Distribution System # EQ37120ET that you referenced features an 8 inch length from the center of the hitch pin hole to the center of the adjustment holes. It can be adjusted to a maximum rise of 7 inches or a maximum drop of 3 inches.

  • Deciding Between the Blue Ox SwayPro and Equal-i-zer for a 7,500 Lb Trailer
    If the estimated weight of your trailer is 7,500 lbs then that means the tongue weight will likely be between 750 lbs and 1,125 lbs. If you take into consideration the weight of any cargo behind the rear axle of the tow vehicle which you should, that puts you slightly over the Blue Ox SwayPro Weight Distribution System part # BXW1000. That said, the Blue Ox SwayPro Weight Distribution System part # BXW1500 would be rated a bit too high as well which is why I recommend the Equal-i-zer Weight...

  • 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...

  • How to Select the Right Weight Distribution System for Trailer With 7,753 lb GVWR
    To start, the way you choose the best weight distribution system is to know your total tongue weight (TTW), which is the tongue weight of your fully loaded and ready to go trailer plus the weight of any cargo behind the rear axle of your 2004 Durango. The tongue weight is typically between 10% and 15% of your trailer's GVWR but you'll want to verify it by using a scale such as the etrailer # e99044 or by using one of the methods outlined in the help article on determining tongue weight...
