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

Yes, if you:

  • Have a trailer with 600 lbs – 1,000 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

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 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.

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.

Picked up my new trailer, traveled through rush hour traffic in heavy rain and wind. Trailer didn't budge an inch, pulled with ease and confidence. Phone Staff was extremely helpful with getting the right product for my needs and it was shipped out immediately putting me on schedule. Excited to hit the road. Thanks etrailer!!

- EQ37101ET

Great hitch. Fast and easy to use. Etrailer.com has super fast shipping.

- EQ37101ET

unit packaged great. Used the on-line instructions and once I found all my tools, it was relatively easy to do.

- EQ37101ET

This hitch works great! Just got back from my first 300 mile round trip pulling a 25' travel trailer and I had no issues at speeds above 55mph. The hitch really helps lock the trailer with the tow vehicle and helps prevent sway! Set up was pretty simple, there were great instructions provided.

- EQ37101ET

I have been highly satisfied with this hitch. we have been using this for a year now and have several trips with using this. I pull with a Ram 1500 and this hitch made night and day difference in the stability of pulling my 35 foot bumper pull camper. i would highly recommend this hitch to anyone.

Works well

Figured out on Saturday what type of anti-sway hitch I needed to order, receive and install by Wednesday night. Tried another site, they couldn't meet the deadline, turned to google and discovered etrailer. Called at 1 PM on Saturday and talked to Steve Z, he got the order placed, and promised to check the status and follow up with me on Sunday. Everything was delivered on Tuesday and that night the hitch was installed, a day ahead of schedule. I don't expect to have a high need for towing / trailering, but when I do I'll be checking and calling etrailer first. On a scale of 1 to 10 their customer service is a 15.

This is my second equalizer wdh. My new truck requires a 2 1/2 inch receiver and my old truck had a 2 inch receiver. Great reliable product. The experience with etrailer.com was top notch. I highly recommend the equalizer hitch and trailer.com

Have a Suburban pulling a trailer with Mustang the product works exactly as states, very easy installation and absolute high-quality. Would recommend it with highest of recommendations and has made a significant difference in the balance of the car. Plus the staff was very helpful with some points of installation.

- EQ37101ET

Excellent buying experience, great web site and customer service. I have used the equalizer hitch before and am replaceing my round bar hitch which was marginally adequate for a 33ft. trailer.

- EQ37101ET

Just received the hitch very heavy duty easy instructions. Bought it for to tow my 30 foot travel trailer. It should do a great job towing and controlling sway.

- EQ37101ET

Had a Fastway e2 liked it and did a fair job, sure was easy to hook up. After research and RV being at 30 feet, ordered the e4 and it made a difference you can feel. etrailer is a place you can buy with confidence and you always know where your order is during transit . Perfect and I recommend the E4 and etrailer.

All I can add is it works and I want pull an every without it. Now that it is broken in it is quieter too.

Drastically improved towing our Airstream with 2017 F250 than just on the ball. Matched with 2 1/2 receiver 6" shank. Easy to install, but need bigger tools than in standard toolbox. Definitely would recommend.

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

World of difference, my wife's truck is our tow pig (2500 yukon) and the nose barely rises even with 750+ lbs on the tongue (~1/2"-3/4"), but you can feel a huge difference with/without WD and sway control. Steering is significantly more positive and responsive due to more weight on the front axle and the trailer handles the wind much better. Excellent product that is easy to install WITH THE EXCEPTION OF THE BALL. I recommend going to an RV place to get the ball put on the head (and I am a VERY handy guy) if you don't already have a massive torque wrench and the random thinwall socket. Not worth the hassle.

A year into ownership, this thing is even better than I originally thought. I will never consider towing heavy of towing largewind affected trailers without this setup. This hitch makes what is a terrifying experience even at 45mph towing our 32+foot travel trailer in heavy winds trust me, Ive tried with a regular hitch setup into a stress-free experience up to 65mph in the same conditions. Awesome piece of kit no true tow rig should be without!

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

Great product. I use it with my '21 Tundra Crewmax SR5 Sport and a 34' Keystone Bullet 290BHS RV. However, there is one major hang up. You have to get your own 3/4 drive 430-foot pound torque wrench and 1-7/8 thin walled socket in order to install and tighten the hitch ball. I had to rent that torque wrench which is about 4' long. Neither Home Depot or Lowe's had it. But Lowe's had the socket. The hitch ball should come pre-tightened to save the customer all this hassle and run around. Be aware of this issue.

  • Is Gen-Y Torsion Weight Distribution Shank Compatible With Equal-i-zer Weight Distribution System?
    I believe you were asking about the Gen-Y Torsion Weight Distribution Shank # 325-GH-1302 because there is not a Gen-Y hitch that fits your 2018 Ram 2500. If so, the answer is yes, you can absolutely use that shank with an Equal-i-zer weight distribution system such as the Equal-i-zer # EQ37101ET. You will need to find the best weight distribution system for your Rockwood 2507S. In order to choose the best system you will first need to know your total tongue weight (TTW), which is the...

  • Weight Distribution Towing Rockwood 2104S with a 2006 Toyota 4Runner
    Weight distribution systems are rated with a tongue weight range that you want your setup to land in the middle of. Because your Rockwood RV loaded weight will be between 6,000 and 7,000 pounds it's likely the tongue weight will be between 600 and 1050 pounds. A trailer's tounge weight should be 10 to 15 percent of its total weight. You will need to choose a system based on the loaded tongue weight. . In addition to the trailer's tongue weight you need to factor in the amount of weight...

  • Weight Distribution or Timbren Recommendation for a 2003 Chevy Silverado 1500
    For eliminating sag on a truck that is towing a trailer the best solution is to use a weight distribution system and not use suspension enhancement. A WD system will level the tow vehicle but since it does so by redistributing some of the tongue weight up to the front axle of the tow vehicle it also greatly improves braking and handling. The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow....

  • Recommended Weight Distribution Hitch for Gulfstream Vista Cruiser
    We have the perfect weight distribution system for you, but in order to ensure you get the correctly rated system, you will need 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 Toyota Sequoia. The ideal system would be one in which your TTW falls somewhere in the middle of the weight distribution system's tongue weight capacity. For your Gulfstream 23 Vista Cruiser...

  • Does Weight of Weight Distribution System Need to be Factored as Additional Tongue Weight
    This is a really good question. So our weight distribution manufacturers have explained it to us like this. The weight distribution system essentially becomes a part of the vehicle's hitch so it's weight does not get factored in as additional tongue weight. Typically when a WD system is being used and there is quite a bit of bounce the issue is that the system is rated too high for the trailer's tongue weight. Or the system isn't setup properly. I'd verify the loaded tongue weight of...

  • Best Weight Distribution System for a 19 Foot Long Airstream Trailer
    The weight distribution system I recommend for your Airstream is the Equal-i-zer Weight Distribution part # EQ37101ET which is rated for a total tongue weight of 600 lbs - 1,000 lbs. This will give you room to add more weight to your Airstream or tow a heavy trailer if the need arises. Also, the tongue weight range for a weight distribution system includes both the loaded ready to tow tongue weight of the trailer and any cargo stored behind the rear axle of the tow vehicle. The Equal-i-zer...

  • Does the Equal-i-zer Weight Distribution System # EQ37101ET Include the L-Pin w/Clips EQ95-01-9430?
    I was able to go out to the warehouse and check the # EQ37101ET weight distributions for you and I found that they all have the new snap pin like the image of the # EQ95-01-9430 you referenced. The shank that offers a larger drop for the Equal-i-zer system that is compatible with a 2 inch trailer hitch is the # EQ90-02-4400. I have linked it to this page for you to check out. It has a gross trailer weight of 14,000lbs, a tongue weight of 600lbs to 1,400lbs, and an overall length of...

  • Does Ball Come Mounted on Equal-I-Zer Weight Distribution and is it Better than Reese or Husky
    The Equal-i-zer Weight Distribution system # EQ37101ET does not come with the 2-5/16 inch ball already installed in the head. It is fairly easy to do though but you will need a thin-walled socket # EQ70-00-4800 to make it easier. We can do it here only if the system is also installed here. A shank is not included with this system. I have included a link to the compatible shanks for you. As far as what is the best weight distribution system it is really a matter of opinion. I would say...

  • Weight of Equal-i-zer Weight Distribution System
    The head unit of the Equal-i-zer Weight Distribution System # EQ37101ET weighs a little over 20 lbs while the pair of spring bars weigh about 35 lb (total, not each). This system does not come with a shank so depending on the rise or drop you need you can use Equal-i-zer Weight Distribution Shank - 12" Long - 8" Rise, 4" Drop # EQ90-02-4200 or Equal-i-zer Weight Dist Shank - 12" Long - 7" Rise, 3" Drop # EQ90-02-4100. I've added links to video reviews of the Equal-i-zer system for...

  • Which Trailer Specs Determine The Correct Weight Distribution System?
    Weight distribution systems are rated by total tongue weight which is the tongue weight of your fully loaded and ready to tow trailer plus the weight of any cargo stored behind the rear axle of your tow vehicle. The hitch weight of 456lbs mentioned is the unloaded hitch weight, and would not be correct to determine a weight distribution system. The easiest way to get an accurate tongue weight rating is with a tongue weight scale like the # e99044, but there are other methods outlined...

  • Hauling a Travel Trailer with my 2015 King Ranch Expedition with Heavy Duty Towing Package
    Your weights look really good here. You can load your travel trailer up to it's GVWR of 7640 lbs. and your Expedition can haul up 15,200 - 15,300 lbs. So there is no issue with overloading your Ford. If you don't have one already you want a brake controller and the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 is my favorite it always works great and is very easy to use. Along with the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers part # 22292 to have a safe...

  • Best Way To Reduce Rear End Sag With a 2019 Ram 1500 Classic Pulling a Toy Hauler Trailer
    The best option for reducing rear end sag on your 2019 Ram 1500, would be to use a weight distribution hitch. The weight distribution hitch will allow you to transfer weight across your Ram to maintain a level ride height. This ensures that you do not have the light steering feel or diminished braking. I recommend the Equal-i-zer Weight Distribution # EQ37101ET with a Equal-i-zer Weight Dist Shank # EQ90-02-4400. The drop shank will allow for up to 9" of drop from the top of the receiver...
