Is this right for you? Product Expert Lindsey S says:

Yes, if you:

  • Have a lightweight trailer with just 400 lbs of tongue weight that has a significant problem tracking behind your vehicle
  • Want an American-made system that lasts from an industry-leading brand
  • Have a lifted truck or a low-riding van and need a bigger drop or rise than you'd get with the standard shank that typically comes with these hitches

No, if you:

  • Hate noise - the steel on steel brackets can create a racket, especially during turns
  • Might be upgrading to a heavier trailer and would want to transfer your hitch to it
  • Don't have a big problem with trailer sway - you might just end up with a really rigid ride
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. Shank sold separately. 2" Hitch ball included. Lowest Prices for the best weight distribution hitch from Equal-i-zer.

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 (sold separately) 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.

I use this WD hitch with my '17 Tacoma pulling a 3200lb travel trailer. Once you have it configured properly, it works great. The trailer tracks straight and true at 65-70MPH, and if a big rig passes you things don't get squirrely. It does OK when making turns in reverse, but I prefer to take a moment once I've reached my spot to remove the sway bars to minimize squeaking. Well worth the money!


Much easier to install than previous sway bar/equalizer. Lighter, easier to handle.
Does the job well, as advertised.
Highlander pulling 20' R-Pod.

Great. Much easier to attach.
Alan F - 07/27/2020


Great product and easy installation, if you take your time.

I ordered this 400/4000 lb WD hitch to replace the same version that was the 600/6000 lb version. The 600 lb version was just overkill for my application ... and it was just WAY TOO HEAVY when installing and removing from the trailer/toad.

If your trailer is less than the 400/4000 lb ratings, then I would definitely recommend going with this hitch. It's just so much easier to store, install and remove.


Very effective!


Review from a similar 4-Point Sway Control in Weight Distribution Hitch

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.


Review from a similar 4-Point Sway Control in Weight Distribution 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.


Review from a similar 4-Point Sway Control in Weight Distribution Hitch

After studying reviews on weight distribution hitches for months, I chose the Equal-i-zer. This thing is designed and built like a tank! It has made pulling my trailer so much more stress free. The sway is now totally absent, where before, the least bit of wind or uneven road surface put me into a swaying frenzy. It took me a couple of tries to get it set up exactly how I wanted it, but now, I couldn’t be happier with the performance of it. One more thing, forget about sneaking into a campground, these hitches inherently creak and pop quite loudly, and you get some really weird looks at times. I just laugh and smile, knowing it’s doing it’s job back there as designed. If you follow the instructions to a T, you should have no problem setting one up, or have a professional do it for you. You will be very happy with the outcome.


Review from a similar 4-Point Sway Control in Weight Distribution Hitch

I borrowed a torque wrench to tighten the ball and shank bolts as mine only goes to 250 ft lbs. After tightening the ball onto the hitch, I installed the Equal-i-zer WDS in about an hour by myself. The directions are straight forward and easy to follow.

I did a short 40 mile pull on a fairly windy day afterwards and I am very satisfied with the anti sway ability of this system. Substantially better than the entry level hitch I bought years ago with my first camper. We are now on our fourth camper and having sold our fifth wheel we bought our third pull behind!!! I tried using my old entry level WDS with chains and a friction brake for anti sway and was nervous the entire 8 hour trip because of sway.

The Equal-I-zer WDS has settled my nerves and loosened my grip on the steering wheel! You can find cheaper WDS out there but you will get what you pay for. If you are experiencing a lot of sway with your current set up, it’s time to upgrade to Equal-I-ler!


Review from a similar 4-Point Sway Control in Weight Distribution Hitch

etrailer was great. Great service and quick and easy. The actual hitch itself was easy to install despite not having the clearest instructions and then difficult to get the sway bar socket to swivel. A lot of grinding metal and leftover burrs in the sockets making them hard to move even when the socket bolts and bush were loosened and all moving parts greased. That part was not machines well. Rest was. I filed and wire wheeled it and got them to move but still very stiff. But it works now and rides well. An hour and half job though took four hours.

It is possible that the weight distribution system could be over your tongue weight. Ideally your total TW will fall in the middle of the systems operating range. This ensures the system is stiff enough to provide the weight shift to your front axle, but without being so stiff that it causes weird handling from the trailer. If your actual total TW is 1200-1300-lbs then a system rated for between 1000- and 1400-lbs would be perfect. There are a couple of other possibilities that could be causing the grinding, however, we would need some more information.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch

Product is fine but shipping is horrible. Items arrived in boxes that were falling apart. UPS had to tape a whole box and parts were falling out when it arrived. Haven’t had a chance to check to see if everything is even in the box. Not acceptable.

I will have Customer Service reach out to you.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch

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.

A whole year has gone by, and Im still extremely satisfied with my equalizer hitch. I hear the squeaks when I make my turns, I know people talk about this hitch being slightly noisy, but every time I hear it I smile. I know its back there, doing its thing, and it does it extremely well. I would buy this hitch again in a New York minute. I am very pleased. Did I say Im VERY pleased? Lol. Its that good.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch

The system works great once you can figure out the instructions. I feel the weight distribution is quite right but the system definitely keeps the trailer from swerving every time a larger truck passes me or if need to pass a larger truck.


Review from a similar 4-Point Sway Control in Weight Distribution Hitch

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.

The thin walled socket needed to install the hitch ball is available as a Related Item here at etrailer. Equal-i-zer offers such a socket as part # EQ70-00-4800
Thin Walled Socket for Equal-i-zer Hitches
. We have also found that the Powerbuilt 1-78 Inch Thin Walled Socket, part # ALL643216
1-7/8" 12pt Thin Walled Socket - 3/4" Drive - Chromium-Vanadium Steel
, works well with the Equal-i-zer system.
-- Etrailer Expert Victoria B - 10/08/2019
My Equal-i-zer hitch continues to perform as I had wanted and described in my review. It has an unstated safety benefit. I tow long distances without a load on my trailer. I keep the Equal-i-zer hitch fully installed but adjusted so there is only mild tension transferred forward. That keeps the receiver ball housing on the tongue of the trailer constantly pressed against the hitch ball. If for any reason the ball coupling lock should fail or have not been set, the trailer would remain coupled to the truck.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch

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 am pulling a 34 foot travel trailer that weighs 7,280lbs. I am very comfortable and feel secure while towing with the equalizer hitch system. There is absolutely no sway even when tractor trailer pass by. I have used other sway control products and systems where I encountered sway and white knuckle rides. I highly recommend the Equalizer 4 point sway control system to anybody thinking about a new or replacing a current system.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch

Took the sway away for the most part. Would be better if you could order it without the drop ball hitch (part that slips into receiver) since I had to get a longer one anyway for my setup.


Review from a similar 4-Point Sway Control in Weight Distribution Hitch

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.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch

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.

After a year of use I can say that the Equalizer has lived up to its promise. It is extremely helpful when hauling autos around in our enclosed trailer. We consider it just part of the normal hauling equipment now.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch

pulling a 24 ft. car hauler with 4 sleds across South Dakota. The hitch made a noticeable difference. Usually pulled with a 3/4 but was using a 1/2 ton last time. I'd estimate it was 75% better in reducing the cross wind effect and the effect of going under overpasses and passing trucks. probably maybe even better if i had been using 3/4 ton as in the past.

Great. It is a game changer especially in a cross wind. Takes a bunch of stress out if driving.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch

The hitch is working great. Our previous hitch could not transfer enough weight to the front of our tow vehicle. After a few minor adjustments our trailer is now towing great!

The usual great service from etrailer. Second of these hitches I’ve mounted and they’re great.


Review from a similar 4-Point Sway Control in Weight Distribution Hitch

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.


Review from a similar 4-Point Sway Control in Weight Distribution Hitch

Fantastic piece of gear. Super heavy-duty. Made my truck and trailer ride so much smoother, brought the back end of my 3/4 ton truck back up to level, and completely eliminated the the swaying I would get from time to time with my dump trailer. Instruction manual that came with the kit was very detailed and well-written. One minor complaint: it would be nice if the ball came mounted to the hitch assembly because most of us don’t have a torque wrench that goes to 430 feet pounds. Beyond that, an excellent investment.


Review from a similar 4-Point Sway Control in Weight Distribution Hitch

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.


Review from a similar 4-Point Sway Control in Weight Distribution Hitch

I towed my camper over 250 miles with the equalizer hitch. Set up and install was very easy. Very little to no sway at all with passing semi trucks.

Purchased last year year best sway control Ive owned. Easy hook up and disconnected from camper. Highly recommend.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch

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.

  • Is a Thin Walled Socket Required when Installing Hitch Ball in Equal-i-zer WD # EQ37041ET
    Although a thin walled socket, like part # EQ70-00-4800, is not required to install the hitch ball on the Equal-i-zer Weight Distribution # EQ37041ET, it will make the job easier. Typically the torque specs for installing a hitch ball are pretty high so it benefits to have a sockect that easily fits inside the spring arm mounting points. the torque rating you will need to use will be attached to the hitch ball.

  • Is Anything Else Needed to Install the Equal-i-zer Weight Distribution System # EQ37041ET
    The only thing you will need to add to the Equal-i-zer Weight Distribution System # EQ37041ET you referenced is an adjustable shank. For this, I recommend the Equal-i-zer Weight Distribution Shank # EQ90-02-4100, which will give you up to a 7 inch rise or a 3 inch drop. For this same system that includes the shank, you can use # EQ37040ET. I have attached a short video demonstration on this system that you can also check out.

  • What Weight Distribution Hitch with Anti-Sway do You Recommend for My 4x7 Foot Trailer?
    With your small 4x7 trailer, a small weight distribution hitch with anti-sway can help level your setup.

This model is a steel-on-steel friction control model that is compatible with tongue weights up to 400 pounds and gross towing weights of 4,000 pounds. If you need to remove the 2" ball that comes...

  • Availability of Equal-i-zer Weight Distribution Compatible with 2-1/2 Inch Receiver

  • Difference Between 2-Point and 4-Point Sway Control on Weight Distribution Systems
    The Equil-i-zer Weight Distribution with 4-Point Sway Control, like # EQ37041ET, differs from the Fastway e2 Weight Distribution with 2-Point Sway Control # FA92-00-0450, because it does utilize 2 more points of steel-on-steel friction at the head of the system. The 4-point system uses a tight connection with the trunnion bars at the head, in a way sandwiching the bar and utilizing that friction to keep it from moving as freely. The Fastway e2 2-point system has a slight gap between the...

  • Longer Shank for use With Fastway Weight Distribution System
    There are some solutions available to you, but we do not carry 18 inch shanks designed for use with Fastway weight distribution systems. Since Equal-i-zer makes a pair of shanks that are 18 inches and have tongue weight capacities between 600 lbs and 1,400 lbs your best option would be to get an Equal-i-zer weight distribution system and shank. For example, Equal-i-zer system # EQ37061ET has a GTW of 6,000 lbs and a total tongue weight capacity of 600 lbs, while # EQ37041ET has a GTW of...

  • Recommended Weight Distribution System for Towing a Motorcycle with a Lightweight Trailer
    I have some solutions for you, but I cannot recommend drilling out holes in a weight distribution system. If you are trying to get parts to match up it is always better to purchase something that was made to fit rather than cutting and drilling to fit your needs. The danger with modifying things at home, especially when they deal with towing, is that it can change the weight capacities and could cause your equipment to not work properly. Since there are no weight distribution shanks that...

  • Recommendation For Weight Distribution For R-Pod 171
    When selecting a weight distribution system for your R-Pod 171, the key factor is the tongue weight (TW) of your towing setup. This means the total load of your trailer with all the gear and supplies included. You will also need to add any weight from behind your tow vehicle's rear axle to determine total tongue weight. TW is 10% to 15% of the total weight of your fully loaded trailer. For example: a trailer fully loaded at 3,500-lbs would have a TW of 350-lbs to 525-lbs. Ideally,...

  • Weight Distribution and Sway Control for a 2009 Jeep Liberty and 2,100 Pound Trailer
    Weight distribution with sway control will absolutely help with the sway issue that you are having. 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 that weighs 2,100 pounds would, by itself, have a tongue weight of around 210 to 315 pounds. You...

  • Weight Distribution System for Pop-Up Camper Trailer with 200-Lbs Tongue Weight
    Weight distribution/sway control systems such as the Husky Centerline # HT32218 work over a range of trailer tongue weight (TW). This particular system is suitable for loaded trailer TW of 800- to 1200-lbs, making it ideal for a towing setup with 1000-lbs of total TW. Note the weight of any cargo behind the tow vehicle's rear axle also counts as TW, something like a generator or a big loaded cooler. Be sure to account for any such cargo weight; add it to the measured trailer TW which...

  • Weight Distribution and Rear Suspension Helper Spring Use in 2008 Chrysler Town and Country
    In general, a properly selected and installed weight distribution system like the Reese Strait-Line # RP66082 will do more to improve the overall towing quality of a trailer than a set of rear air bags in the tow vehicle. The WD system actually shifts trailer weight to the vehicle's front axle to restore traction (for better steering and braking) while an air bag kit will essentially just prevent rear-end sag by stiffening the suspension. The results of these two different strategies, a...
