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.

Average Customer Rating:  4.8 out of 5 stars   (633 Customer Reviews)

Steel-on-steel friction works to prevent and correct trailer sway in this unique weight distribution system. Sway control brackets ensure that your trailer stays in line with your tow vehicle. 2-5/16" Hitch ball and adjustable shank included.


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.


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.


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

-- 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.

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.

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.
Tony - 09/06/2019


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.
Jeff - 01/17/2022


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!


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.


A little noisy but it works awesome and makes towing so much more comfortable. I have a custom trailer that is a little too tongue heavy. This hitch helped me get things leveled out and stable. The etrailer people were very helpful with recommendations for ways to mount the brackets on my trailer frame. No regrets here.


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.
Raymond L - 09/30/2019


Ordered this product for the built in sway control. My last hitch required another device to achieve this, but I didn't care for the additional work when backing up or on wet surfaces.

The order shipped quickly and arrived intact in 2 separate packages. The smaller of the two, contained the hitch shank and main body. It's heavy, so it was expected that the box would have a hole. The other larger package was sealed and intact. All parts were present.

Setup was straightforward, documentation excellent. Particularly the places to annotate measurements. The manual was small but effective. The ball mounting requires a thin walled 1 7/8 socket. I didn't buy this, my RV dealer torqued my setup for nothing.

Very satisfied with this hitch thus far. Will update when I have had a chance to put it through the motion.


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.


Just bought a new Travel Trailer, had been using a Reese Weight distribution set up with traditional sway bar. This system worked well but had the tractor trailers pushing me around and on windy days I had to reduce highway speeds dramatically. So, I chose to upgrade to the Equalizer for the new TT. I had the Professionals install it since it was raining but the videos and information on etrailer make me confident I could have done it with the correct tools. The Equalizer was fantastic on the 75 mile ride home in the rain with heavy Tractor Trailer traffic. Had little to no sway. Very pleased with my decision. This is a heavy duty system and is easy to hook up.

I ordered by calling etrailer because I had a question about shipping and delivery since I needed the new set up for delivery of my new TT. Lisa was more than helpful answering my questions and getting the hitch to me on time.

I strongly recommend The Equalizer and etrailer for your towing needs.


The Equalizer Wt Dist W Sway Con And Ball
Gtw, 1000 Tw. Was recommended for my application and works great. [Local retailer] in New York did the installation on my New 2017 Starcraft ultra light. The product has a clean look on the trailer. The Equalizer is a great product for tight turns and backing into parking slips. No need to remove sway controls, because its incorporated into the Patented Design. I've used other styles in the past but this is the product for me.
Thanks Etrailer for the on time shipping of the Equalizer.
Did you Equalize your trailer today!!


Product arrived on time and in good condition, I ended up having to purchase another shank with maximum 6" drop. The description I found of the standard shank on your web site stated Maximum drop: 3" from top of hitch receiver opening. I interpreted this to mean the shank at it's lowest setting would allow the top of the ball to be 3-inches from the receiver height. Actually at the lowest adjustment the top of the ball is approximately even with the top of the receiver. Just spent another $116.95 which I was not counting on. The standard shank that comes with the package is non-returnable by itself

Fits: 2" x 2" trailer hitch receivers
Tongue weight: 600 lbs - 1,400 lbs
Overall length: 12"
Maximum rise: 7" from top of hitch receiver opening
Maximum drop: 3" from top of hitch receiver opening
Incremental adjustment: 1-1/4"


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!
Mason - 07/02/2021


The E4 is worth its weight in gold. This hitch has completely changed our 1/2 ton’s ride quality


I was quoted it would cost $900 for a local camping shop to put on the weight distribution hitch. I looked into eTrailer and found one much cheaper. It was delivered quickly and with free shipping. Through talking with them via email and watching the instructional video, I easily installed it myself in a couple hours.
The electric jack was also purchased through eTrailer and installed in 20 minutes.


I ordered this to pull our camper, it came the very next day. It pulls the camper no problem doing 60mph. You do have to get a special socket for the ball, but asked my local RV dealer if they could tighten it for me and they did. I couldn't be happier with this system! You won't be sorry with this hitch system or the company!


From the first moment I called this was a wonderful experience. William B was the gentleman I got on the phone and he was very helpful and extremely knowledgeable about the product. He helped me order the right size hitch and it arrived in three days. I installed the hitch and while yes it’s noisy as other reviews say it is the best hitch I could’ve purchased. I own a 2014 Chevy Silverado 1500 and am pulling a 20’ enclosed V nose trailer. I can do 70 with no problem or any seaway whatsoever. Thanks again Will.


etrailer promptly sent my equalizer weight distribution hitch to me and even price match it with a competitor with a refund.
I like the unit a lot


This product is very heavy duty and has done well with the camper we use.


Helps with sway but don't expect it to take it all away.


I towed a 37" Grand Design from Brainerd Mn to Kansas City using my 2008 single cab F-250 without any problems.

Worked great

We still have it and it’s been working great. If I need anything else, I will definitely let you know. I had a very tight timeline and you guys made sure I received it before picking up the new trailer. Thanks again
Anthony - 08/21/2018


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 a Weight Distribution System Required for a Trailer Over 20 Foot Long with a Nissan Armada
    I looked in the owner's manual for a 2017 Nissan Armada which should be the same for a 2016+ and it did not have any restrictions for towing a trailer over 20' long. The only restrictions I had seen in regards to what the trailer must have is in regards to brakes and weight. If the trailer is over 3,500 lb then it must have a braking system. It is also recommend that a weight distribution system be used if the trailer is over 5,000 lbs. With that being said I cannot say I have heard of...

  • Can Weight Distribution be Used on Vehicle with Air Suspension Enhancement
    You can use weight distribution with air suspension enhancement. The trick is to inflate the bags first to the desired PSI and then go through the setup process of the weight distribution system. The two systems can work great together but typically if you have WD you aren't going to need additional suspension enhancement.

  • Will Weight Distribution Prevent Trailer Sway at Speeds Near 50 MPH
    Ideally the loaded tongue weight of the trailer (which includes weight of all cargo behind the rear axle of tow vehicle) falls right into the middle of the weight distribution's range. That said, the type of persistent sway you mentioned having is not going to be fixed by a WD system. You most likely have not enough tongue weight relative to the total weight of the trailer (you need 10 to 15 percent) or your trailer has worn out suspension components which you would need to check for and...

  • Can Equal-i-Zer # EQ37100ET be Used on Trailer with 600 lb Tongue Weight
    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. 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. The part # EQ37100ET that you referenced...

  • Do I Need to Adjust Weight Distribution System After Installing Air Springs
    If the truck is still the same distance from the ground after the air spring installation as it was before the air spring installation then you may not need to adjust the equalizer hitch as long as the truck is level with the trailer. The point of the adjustable weight distribution shank is to keep the truck level with the trailer frame.

    Yes, if the trunnion bars of your Equal-i-zer Weight Distribution System # EQ37100ET have swung off the rear brackets your weight distribution system will not operate as designed and reduce trailer sway. To correct, you can start adding washers until all 8 washers are used before going to adjust the L bracket. The trunnion bars do not need to be parallel exactly with your trailer.

  • Determining If 2017 Dodge Durango Can Tow 5,600 Pound Trailer with Passengers and Cargo
    I took a look at the online version of your 2017 Dodge Durango's owner's manual and for the 5.7L engine with AWD it lists a maximum trailer weight of 7,200 pounds and a GCWR (Gross Combined Weight Rating) of 13,100 pounds. This GCWR basically means that when towing a 5,600 pound trailer your Dodge Durango can't weight more than 7,500 pounds.

  • Does the Weight of Weight Distribution System Count as Tongue Weight
    That's a really good question. We've asked our weight distribution system manufacturers this before and they all state that the weight of the WD system does not count as additional tongue weight. Basically it becomes a part of the hitch/frame of the vehicle so although these kits are heavy they do not "add" to the tongue weight figure.

  • Why Would One Spring Bar Be More Difficult to Connect than Other on Weight Distribution
    Assuming you are using the exact same adjustment for both sides of the trailer if one of the bars is easier or harder to install than the other that would most likely imply that one side of the trailer weighs more than the other or the trailer isn't sitting level left to right. I would recommend measuring from the top of the fender to the ground on either side of the trailer and compare the measurements to see if they are the same if not that would explain why one bar is easier to connect...

  • Best Equal-i-zer Weight Distribution System for a 2015 Skyline Koala Super Lite 26SS
    I would have to agree that the Equal-i-zer Weight Distribution System part # EQ37100ET would be the best system for your 2015 Skyline Koala Super Lite 26SS. You made a great choice for a weight distribution system as well. In order to make sure this system is correct you will need to load the trailer like you would when ready to tow and weigh the tongue. Once you know the tongue weight of the trailer you can then add the weight of any cargo stored behind the rear axle of your tow vehicle...

  • Is Equal-i-Zer Weight Distribution System Sway Control Better than EAZ Weight Distribution
    The 4 point sway control of the Equal-i-Zer Weight Distribution systems like the part # EQ37100ET is superior to the sway control of an EAZ kit like you have. It would be much more effective handling the sway caused by a passing vehicle. Going to this kit will give you additional sway prevention. I'd also try moving as much cargo weight forward as possible in your trailer as that's typically the best way to prevent sway.

  • Information for Understanding Towing Capacities of 2016 Ford F-150
    Towing capacities are a combination of several factors including but not limited to: hitch capacity, frame strength, braking power, suspension capacity, cooling system capacity etc. Ford states that your tongue weight capacity is 1,150 lbs and the total trailer weight capacity is 11,500 lb (which is a lot for a 1/2 ton truck) then you have to stay under both numbers. If the trailer weighs 10,000 lbs but the tongue weight capacity is 1,300 lbs you should not tow that trailer. The hitches...

  • Can Weight Distribution System be Used on Jeep Cherokee with GC Air Suspension System
    A weight distribution system like the Equal-i-zer # EQ37100ET can indeed be used on your Jeep Cherokee that features the air suspension auto-leveling system.

  • Recommended Weight Distribution System for 2019 GMC Yukon Denali and 800 Pound Total Tongue Weight
    You've done your research! For your towing setup that has a total tongue weight of around 800 pounds I highly recommend the Equal-i-zer Weight Distribution System # EQ37100ET. Your total tongue weight falls right in the middle of its 600 to 1,000 pound tongue weight capacity range and the Equal-i-zer systems are considered by many to be the best on the market because of their superior 4-Point Sway Control. It uses two points of pressure within the hitch itself and two friction points where...

  • Could 1,000 lb Tongue Weight Equalizer System be Used on 5k Trailer
    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. 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. Tongue weight is typically 10-15...

    Yes, if you use a weight distribution system that is rated too high for the tongue weight of a trailer the ride quality will be incredibly stiff and harsh.

  • Will a Weight Distribution System Fix Sway that Occurs at 50 MPH
    Sway at the speed you listed will not be fixed by a weight distribution system. You either have a trailer that is not sitting perfectly level or you the trailer doesn't have enough tongue weight. You need the tongue weight of the trailer to be 10-15 percent of the total weight of the trailer. In most cases if you just move as much weight to the front of the trailer as possible that will solve the problem as well. The Equalizer weight distribution system part # EQ37100ET would be an excellent...

  • Is the Equal-i-zer Weight Distribution System EQ37100ET Too Stiff for a Tongue Weight of 615 lbs
    When looking for a Weight Distribution (WD) system you will first need to figure out the Tongue Weight (TW) of your fully loaded and ready-to-go trailer. You will then take that and add the weight of any cargo behind the rear axle of your tow vehicle. Once you have that total, you will then need to make sure that the WD system that you pick out has a range where your total falls inside of. Normally your trailer TW should be between 10-15 percent of the weight of your trailer. Since you...

  • Where are the 4 Points of Sway Control in Equalizer Weight Distribution Systems
    A system with 4-point sway control such as Equal-I-zer hitch # EQ37100ET has the 2-point as mention above in the L-brackets and then also sway control where the spring bars mount in the head. In both cases the sway control is resisting movement side to side (sway) and in most cases can only be overcome by the force applied to the system from the vehicle making a turn (which is why you are still able to turn with the trailer).
