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.

Video Transcript for Equal-i-zer Weight Distribution - WD With Sway Control - EQ37100ET Review

Today we're gong to be taking a look at the Equal-i-zer Weight Distribution System with 4 Point Sway Control, this system is going to have tunnel weight rating of 600 pounds to 1,000 pounds and a maximum gross towing weight rate of 10,000 pounds. Now what this system does is it evenly distributes weight over the axles of your tow vehicle and your trailer which is going to offer better stability and better control. Ultimately a weight distribution system is going to create a more level ride for both the tow vehicle and the trailer. Now again, this one's going to have integrated 4 point sway control which is really going to help limit side to side movement of your trailer. We're going to have these brackets right here that are going to keep the spring bars in place for a rigid system that holds the trailer in line at all times. This unit does not use lift chains so that way the spring bars aren't able to move freely, they're going to be held in place and they're going to slide back and forth, which is going to create steel on steel friction. Down here we're going to have 2 points of sway control that are created by the steel on steel friction that occurs when the spring bars slide within these L-brackets that are mounted on the trailer tongue. The other 2 points of sway control are here at the head assembly, it's a really nice feature of the unit.

The downward pressure that is placed on the hitch ball by the trailer is combated by the upward pressure that is exerted by the spring bars that are mounted into these sockets right here. Those are going to be held in place with pins and clips, nice sturdy durable design there. The upward force that's placed on the spring bars on either side of the system creates the rotational friction that essentially forces your trailer in line at all times. With this system we're going to have direct friction that's applied to the spring bars. It's really going to help stop sway right away. No additional parts are needed, nothing that can be added on to increase it's all built in, it's integrated and it's going to provide an extremely durable functional sway control system.

That's a really nice design of the unit. Now the unique design of the unit makes this system compatible with surge type brake actuators. Another neat features of this system is that you can back your trailer up without having to remove or uninstall any components. These spring bars are going to flex appropriately over uneven terrain which is going to offer a really nice control to even ride without the bounce. It's also going to be very quiet. These brackets are no drill clamp on brackets that can be adjusted along your trailer frame to accommodate frame mounted accessories such as gas tanks, tool boxes or generators. Then when it comes to the head assembly the desired tilt is achieved by using a traditional washer design.

It's going to come with this spacer rivet and it's going to come with some washer right here so you can add or remove washers from the spacer rivet to tilt the head up or down. Underneath the head assembly there's going to be a slot right there for that spacer rivet to be installed. The unit's going to come with your detailed installation instructions and owners manual and it's going to help walk you through the appropriate tilt for your application. Then also underneath the head assembly or underneath the hitch ball there's going to be an angle set bolt, you'll need to tighten that down a little bit. That is included to make sure that the spacer rivet is in correct positioning when it comes to making sure you get the tilt you need for your application. The unit's made from a strong steel construction, it's dip steel.

It's going to very durable and corrosion resistant, it's got a really nice finish on it. It's going to last a long time and it's going to look great for a long time. Now the system's going to come with everything that you see here on the table, as well as the detailed installation instructions and owners manual that I mentioned earlier. It also comes with your 2-5/16 inch hitch bar rated for 10,000 pounds. It's got the lock washer underneath as well as the nut to get it fully installed. You will need to get that torque down to the specifications listed by the manufacturer. One of the things that I want to mention that will make that process easier is using a 1-7/8 inch thin walled socket. It is recommended for the hitch ball installation. We do carry that here at etrailer.com, it's sold separately you can find it with part number EQ70-00-4800. That's also going to come up, or excuse me it's going to come with this snap up lever. This is designed to ease installation by reducing the amount of lifting required by the trailer jack. When you're getting your arms in place on these brackets. You can see that the unique design of our brackets allow for the unit to fit a variety of trailer frame sizes. Again, the hitch ball on the unit is 2-5/16 of an inch. The adjustable shank is designed to go into a 2 inch by 2 inch trailer hitch receiver that's rated for use with the weight distribution system. The brackets are going to fit trailer frames with the height from 3 inches, that would be at the lowest setting right here all the way to 6 inches, so 3 inches, 4 inches, 5 inches and 6 inch tall trailer frames. I want to mention just the adjustable shank here. I don't have it fully installed just because I wanted to be able to take it out and show it to you. This is going to feature a 6 hole design, so that's the amount of adjustment holes that we right here on the upright bar of the shank. These holes are going to be separated on center by an inch and a quarter. The shank length, I took a measurement and I'll do it again for you, place it right here. We'll go over some measurements real quick with that. The overall length of the shank from very front to very back is going to be 12 inches. If we take a measurement from the center of the adjustment holes to the center of the hitch pin hole we're looking at 8 inches. From the front of the shank to the center of the hitch pin hole we're looking at a measurement of 9 inches. Then from the back of that upright bar to the center of the hitch pin hole we're looking at about 7 inches. Now if you're using this in the rise position you want to make sure you have enough clearance at the back of the vehicle with this support bar right here. It's a welded construction, nice solid steel design. I'm going to give you a measurement from the bottom of that base right there, that brace right here at the weld so at the base of the brace to the center of the hitch pin hole. We're looking at a clearance measurement of around 4 inches. Again, that's only going to come into play if you're using the adjustable shank in the rise position like this. Real quick just to go over the hardware that it comes with. Again, we talked about the snap up lever. It's going to come with this set right here. This is all to get the head assembly installed on that adjustable shank. Then you've got your spacer rivet with the washers and then you're also going to have a 5/8 inch diameter hitch pin and clip to get the adjustable shank installed in your trailer hitch. Now if you're using this in the rise position with the head assembly at the highest setting it's going to give you a maximum rise of 7 inches, that's measuring from the inside top edge of the receiver tube of your hitch or the top of the shank to the top of the ball platform. If you flip this over to the drop position and lower the head assembly at the lowest setting it's going to give you a maximum drop of 3 inches from the inside top edge of the receiver tube of your hitch to the top of the ball platform. These spring bars, again they're held in the head assembly with a pin and clip, very easy to get those installed as well as to remove them. These are going to measure 36 inches long and then they're going to give us a width measurement of 1 and 3/8 of an inch. They're a nice square design. The product is made right here in the USA and it's going to be covered with a limited lifetime warranty. That's going to do it for today's look at the Equal-I-zer Weight Distribution System with the 4 Point Sway Control.

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. 679579

I think this hitch saved our lives and probably others. This is my first "big" camper I've been towing trailers and pop ups for years. A 23' Grey Wolf Toyhauler with my 2011 Ford Expy as the TV out in front. I had been talking with more mature campers from work about the high prices of some of these WD hitches.... who wisely advised... don't go cheap on tires, brakes or hitches. I bit the bullet, took a little heat from the wife, cause I had it professionally installed too. (This thing is massive). I'll add pics next time I hookup. Plus rolling on $1200 of new Good Year AT's So me and my wife had just pulled out from Clabough's camp grounds after a week of great exploring, great weather and fun smoky Mtn motorcycle riding. We were heading north on 441, not to the highway yet. Probably not on the road more than 20 min or so driving through a small town. Maybe Severville Anyway, 4 lanes, maybe 40mph or 45mph. Following a car, and just talking. Then what seemed to be out of no where, I looked up to see the car was stopped at a red light right in front of us. When did that light turn red!! I had less than a second to react. I knew I couldn't stop. No one coming left or right at the intersection. No one to my right. It was tight, but I might be able to make it.... I swerved HARD right, then back with a HARD left... missing the car in front of us, and the sidewalk. We went sailing through the intersection totally unscathed... and THE CAMPER FOLLOWED ALONG PERFECTLY!! Silence. Neither of us said a word for what seemed like 5 minutes. I'm not even sure who spoke first. I recall someone saying like, did that just happen? And "we're not doing that again" So guys, it may seem like a lot of money, but I'd say it's pretty cheap. I'll just repeat what I was told... don't cheap out on tires, brake, or hitches. Happy camping. 422706

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. 426708

This is one slick setup. I got it tuned in perfectly on the second try. Instructions are very specific and very accurate. I found only one thing that could be better - the bolts that hold the ball mount to the receiver bar are too long, at least 1" too long. A standard socket won't fit over them to torque the nut - shorter bolts or a warning that a deep socket is needed would be nice. This seems like an anomaly, as everything else was a perfect fit. Good price, speedy delivery, as always. One caution, this thing is heavy! 283591

Lindy was very helpful verifying the correct model for my new 19 ft TT. The hitch arrived in 2 boxes - very heavy! This hitch is built like it belongs on a tank - glad I purchased the hitchgrip carrying tool. All of the parts are heavy duty and well finished. The etrailer installation video on YouTube is very helpful to better demonstrate the installation manual instructions. My dealer installed the ball since they had the thin-wall socket. Everything installed easily and fit well. Need to load up the new TT and make final adjustments if necessary. 493532

I have a new 2012 F150 Ford XLT which does NOT pull my trailer as well as my old truck. I was not comfortable with the amount of sway and could not go over 50mph. On Sunday night after returning I purchased the Equal-i-zer. On Thursday it arrived and we literally had to look at the instruction book once. After 30 minutes the installation was completed and no extra parts... I merged onto the highway to test the equipment. I reached a cruising speed of 70mph and had absolutely NO SWAY. The fact that I now have a piece of mind knowing that the Equal-i-zer is less than that of a life when you are towing without the proper equipment. Other products may be available but research was extensive before I purchased the Equal-i-zer. The shear strength is visible and the product is very well made. The fasteners are heavy, the hitch is heavy, and the stabilizer bars are heavy. This is a 5 star product and every trailer owner should own the Equal-i-zer. The best thing about all of this is it was a product that was sold without a gimick and does the job well. Hat's off to you!! Scott S. 47603

I have bought a F150 2013. having simular issues do you know the weight of your trailer I have apx. 5500 lb trailer tongue weight about 550 to 600 lbs
-- comment by: mark b - 11/24/2013


The 550-600 tongue weight falls into an in-between area with Equal-i-zer weight distribution systems. The 6K system is built for 400-600 pounds tongue weight, and you are at the end of that range so it may not be a good choice particularly if you have any gear in the tow vehicle rear of the axle. Remember any weight behind the axle counts towards your tongue weight. The next step up is the 10K system featured on this page with a recommended tongue weight range of 400-1000 pounds. Now this would work, but it may be a bit overkill. The extra tension of these bars when paired with a 600 pound tongue weight may ride a bit stiff. If you are not particular to the Equal-i-zer systems, you may want to check out the Fastway 8K system, part FA92-00-0800. It may be a bit closer of a match to your trailer.

Great weight distribution system! Easy to install and adjust. I've used it for over a year now and find it quick and easy to use. However, I quickly lost the black 'persuasion bar' so paint yours red for better visibility when you set it down (although you'll rarely need it). 488981

Hitch has performed great after a year. Quality is good, 4-pt sway control is noticeably helpful, but only if you have the hitch setup correctly. I had the RV dealer set this up for me, and the first 300 miles of towing a 7,000 lb trailer with my F150 was rather uncomfortable. Once at my home, I spent a good 30 minutes dialing in the hitch, and now it works great. It IS squeaky in turns. We use white lithium grease (at the front of the hitch, not the rear L brackets that need the friction) and it helps, but it still is a little embarrassing pulling out of the gas station as it creaks and we get "the stares." If I could buy it again I definitely would, despite the turn squeaks because it is easy to connect and disconnect, it provides decent sway control, and the price is attractive. If you are on the fence about the 10,000lb unit or the 12,500lb, I wish I would have bought the higher unit for my 7,000lb load. Because I am nearer to the limit of WD for the 10,000lb unit, it requires lots of the included washers to angle the hitch head to the proper geometry for the load. The hitch head angle then makes disconnecting my trailer somewhat tricky if I am at an unlevel campsite. The head will snag the trailer ball and I'll have to rock the trailer back and forth to get it to disconnect. I think the 12,500lb unit's stiffer arms and thereby better geometry would release better... YMMV 600852

Worth every cent. We bought a 2008 26' Sun Valley Road Runner two weeks ago and immediately took it on a trip to the N. Georgia mountains behind our 2006 Silverado 1500HD. Very scary up and back with a serious sway problem that kept me from going over 50 mph. Upon returning I researched heavily on how to "prevent" sway and not just "reduce" it. Your website was extremely helpful in explaining the differences in all the products available. The product reviews were very favorable for the Equal-i-zer four point system so it made my decision an easy one. Within two days of ordering, it arrived and I just installed it today. It was very easy to set up. I took it out for a run on the interstate and WOW what a difference! I could run along at 65-70 mph with absolutely no sway and very little bounce. This is the first time I had to buy a weight distribution system and if I ever have to do it again I will certainly go back through etrailer.com. The Equal-i-zer is a great product. 281160

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. 517401

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.

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" 564621

Honestly a great purchase. Read a ton of reviews before buying. Had the traditional style weight distribution hitch with sway bar attachment before, and I'll definitely say that I have no intentions of going back! The sway control is absolutely great. Hauled a 30' travel trailer from Atlanta, GA to upstate New York and back with absolutely no sway issues whatsoever. If set up correctly, it should do the trick. I will say, however, that it can be slightly loud at low speeds, but is just something to get used to. Would recommend this hitch to anyone. Worth the investment. 338779

The hitch works great. Distributes load and no sway. I have a Dodge Diesel pretty good weight to balance against 7500# trailer so trailer isn't going to push around anyway. I like ability to back in to spaces not having to drop load from hitch. I use the plastic inserts (which should be included not extra, MHO) and hitch does not make noise. It takes serious focus on instructions to setup hitch. I had to reduce amount of load pushed to front of truck because it caused loss of traction. The torque on fasteners was beyond my tooling capabilities so set hitch, tighten as much as possible then took to Les Schwab who accomplished the finish torques. I would buy it again. 329832

Hitch has functioned flawlessly over the last year. No sway on hiway. Im about to move hitch to new tow vehicle and readjust. The new truck is much lighter than original tow vehicle. The hitch will hopefully provide the stability between lighter tow vehicle and same trailer. We shall see

After many hours of reading reviews and research on this weight distributing hitch I am very impressed with the quality of this hitch and the fact that is American made in the USA. I have a new 34' 2016 Tracer travel trailer which I will be using this hitch with. I have been using a easylift spring bar hitch with the brake pad type sway control. Never was that satisified with it. This equalizer is a very impressive hitch. The staff a e-trailer was very helpful in suggesting and recommending this hitch. I talked to a different sales person on 3 different calls and they all gave me great information. E-trailer has one of the most informative advertising and videos on the internet.They met a price match of another offer with no beating around the bush. I would highly recommend them and plan to use them in the future.Order was shipped on Friday and I received it the following Wednesday.Thank you E-trailer and staff... 235462

I am very pleased with the hitch and its operation. I dont miss the old chain style hook up.This is so much easier to connect to more important is its performance while towing. I highly recommend this hitch.

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. 525174

after searching multiple websites for the Equalizer 10,000lb gtw/ 1000 lb tw weight distribution and 4 point sway control hitch, E-Trailer had the best deal for the this hitch. Not only the best deal but the best price and free shipping as well. In addition E-Trailer also offered a great price pledge, if you find an equal product cheaper they will price match. When I found a cheaper unit and emailed E-Trailer they matched the cheaper price and I saved another $xx.the hitch was also shipped quickly and I received it 3 days later. Their customer service was great. they were informative, polite and quick with all parts of the transaction, including the price match refund. great, price, great service, I would recommend them and will shop with them again. 319704

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. 486062

The Hitch its self is awesome I just docked it a star because of cheap hardware. The sway is minimal the truck rides great and level and with the pads for the L-brackets noise is minimal. Like many vendors their hardware is not up to the task. I had the washers on the 3/4 bolts that hold the Head to the shank literally disintegrate(they cracked in so many places it was like a spider web). Luckily they held till I got home then I got some Military spec washers and they seem to be doing fine. 429312

The Equalizer Wt Dist W Sway Con And Ball 10k 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!! etrailer.com 352111

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. 562089

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.

We bought a new Northwood Nash 26N trailer in West Texas and towed it 112 miles to our home on a very windy day. I was very uncomfortable during the drive, and decided right then we would research the solution before going out to see "whatever". We did extensive research on weight distribution and sway control. We also researched our specific tow vehicle and trailer requirements regarding towing and trailer control while doing so. Based on our initial research, we began researching specific products. We did much of this on the web reading recommendations, reviews and a myriad of other sources. In my opinion etrailer has one of the very best websites for researching anything related to tow vehicle and trailer solutions and products. Research indicated that the best solution for our situation was a weight distribution system that incorporated a 4-sway control in the same package. Knowing our approximate tongue weight and towing GCWR numbers, we selected the Equal-i-zer EQ37100ET. The install took one day for me to do alone except for help torquing the 2 5/16" ball nut, which is to be torqued to 430 ft-lbs. Equilalizer literature suggests you go to a local dealer to have it done "for a reasonable fee" if you cannot do it yourself. They also suggest it be checked before every trip. To me that is a crock. As a Marine tanker in the RVN days, I know a thing or two about long bars and torque. The tag on the ball said "thread should protrude from the nut when properly installed". With my 110 lb wife holding an 18" adjustable wrench and my 150 lb frame standing off about 8-10 feet with bar in hand we accomplished "thread protrusion" dictate. I did buy the recommended "thin wall" socket to fit up into the head. I have a "thick wall" socket and it may have worked, but the thin wall ensures a good snug fit onto the nut. You have to have a person holding the socket on the breaker bar up on the nut, or support it in some way as I did to prevent it from dropping down. I used a 3/4" drive breaker bar with the thin wall socket and the torquing went well. I would think most DIY folks would find the thin wall socket to be of good use. That was the most difficult part of the entire install. For the most part the install is straight forward. However, I am methodical and read instructions many times as the install progresses. So Day 1 ended well. Day 2 was spent on the set-up and adjustments required to maximize the effectiveness of the system. This is not a quick process, nor should it be. Getting the set-up precise is paramount to getting the system to work properly. I did an initial set-up without having either the truck or the trailer loaded for "today's travel" and we were over adjusted. For me, I was just trying to get "a feel" for the process. We were over adjusted and on Day 3 I removed one shim and did it all again. This time we were within 1/16" over adjusted. Good enough for now. Went to the truck stop and got our weights; combined truck/trailer, truck, and calculated trailer. To get to the truck stop we used I-20 for about 7 miles and return, again on a very windy day. What a difference from the initial run in from West Texas. Oh yes, there were a few sways experienced as we traveled through construction constricted areas but everything felt and was "in control". In summary, this is not a product that will be useful if you just want to hook it up and go. Frequent attention to detail is and will be required. But as with all things, if you put in the work you will reap the rewards. I highly recommend this product if it is the solution to your tag along trailer weight distribution and sway control issues. 732986

Product was shipped fast! It arrived in 2 boxes, some tearing of boxes, but all items were accounted for. The manual that came from the manufacturer was very helpful, and easy to understand. I did call the toll free number of the manufacturer to get a clarification on an item in the installation book, they were very helpful. . Final test on the installed product will come the week after Christmas, more review after then 728354

  • Excessive Trailer Sway While Towing with Late Model Ford F-150 Using Sway Control

  • Weight Distribution Hitch for 2018 Coleman 263 BH Tandem Axle Travel Trailer GVWR 7600-lbs
    The specs I found for the 2018 Dutchmen Coleman Lantern 263BH tandem axle travel trailer indicate a dry weight of 5871-lbs and a payload capacity of 1729-lbs. Added together these become the GVWR for the trailer, the gross vehicle weight rating, the most it can weigh when fully loaded and ready for the road. In this case that GVWR is 7600-lbs. The rule of thumb is that a trailer must have tongue weight (TW) of 10 to 15-percent of the trailer's gross weight. I would suggest to try to...

    Whew. That's one heavy trailer! As long as the trailer tongue weight won't exceed 1600 lbs, the # EQ90-00-1600 Equal-i-zer Weight Distribution System would be ideal. This particular system is meant to be used in a Class V hitch with a 2-1/2 inch by 2-1/2 inch receiver. This is the highest rated system Equal-i-zer offers. If your trailer's tongue weight will exceed 1600 lbs, the next step up is the Reese # RP66075 Strait-Line, good for up to 1700 lbs of tongue weight. The sway control component...
