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.

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.


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

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.

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.


Comments
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.


Comments
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.

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.


Comments
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!

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.

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.

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.



- EQ37100ET

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.

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.

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"

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.

You won't be sorry with this hitch system or the company!

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.

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.

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.

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.

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...

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.


Comments
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

    Using an extension in your trailer hitch will reduce the capacity of the hitch by 50 percent. There are no extensions available that are designed to work with weight distribution. When choosing a weight distribution system for your F-150 towing a trailer is to find a system where the total tongue weight is near the middle of the range for the system. With your tongue weight at 400-lbs and you said an additional 400-lbs behind the rear axle you need a system that has 800-lbs near the middle...

  • Can 2019 Ford F-250 Sway Control Work with Equal-i-zer Hitch
    The factory integrated sway control will work great with the Equal-i-zer kit part # EQ37100ET that you referenced. Neither system would interfere or compete with the function of the other so it would be totally fine.

  • Weight Distribution System With Empty Trailer
    Weight distribution systems have a total tongue weight rating range. When you use weight distribution, you need to account for the loaded tongue weight of your trailer along with any cargo behind the rear axle of your towing vehicle. Ideally, you want to be in the middle of this range when loaded. When unloaded, it is ideal to fall within that range as well, but that isn't always possible. With a 24 foot enclosed trailer, you most likely will still have enough tongue weight to utilize...

  • Equal-i-Zer Weight Distribution System Recommendation for 8,000 lb Trailer
    I have a better solution for you, but with your relatively lighter tongue weight on your trailer you are probably going to have sway that you won't be able to fix until you get your tongue weight up to around 10 percent of your trailer's total weight. Moving cargo forward in the trailer will accomplish that. Once you do that you'd then want the Equal-I-Zer Kit part # EQ37100ET that you referenced. This has a tongue weight range of 600 to 1,000 lbs.

  • Equal-I-Zer Weight Distribution System Recommendation for Jayco JayFlight 212QBW SLX
    If we assume your trailer will be fully loaded at 6,000 lbs that means the tongue weight would be most likely between 600 and 900 lbs. Based on that the correct Equal-I-Zer system you'd want would be the part # EQ37100ET which has the tongue weight range of 600 lbs - 1,000 lbs and would be perfect for this.

  • Equal-I-Zer Recommendation for Flagstaff Micro Lite Trailer Dry Weight 4,500 lbs
    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. So when your trailer is loaded it...

  • Best Weight Distribution System with Sway Control for a 2000 Fleetwood Mallard M-29Y
    It would be hard for me to speak of the weight distribution system you have without knowing the brand, model, and capacity. However, a weight distribution system is only effective if it is properly rated for the trailer. The average tongue weight of a trailer is between 10 and 15% of the gross trailer weight (GTW). I looked up your 2000 Fleetwood Mallard M-29Y and it appears that if the trailer is loaded correctly, you should have a tongue weight between 500 and 750 lbs. You will also need...

  • Distance from Center of Pin Hole to Center of Ball Hole on Shank in Equal-I-Zer Weight Distribution
    On an Equal-I-zer weight distribution system such as # EQ37100ET the pin hole to ball hole measurement can vary slightly depending on the angle of the head. But generally it is approximately 13 inches center to center.

  • Should I Spread the Trailer Axles Out or Use a Weight Distribution System
    Generally speaking, you will want to load the trailer with 60% of the cargo in the front and 40% in the rear. I do not recommend spacing the axles out as they are in the location predetermined by the manufacturer to be best for the trailer. Instead, I recommend using a weight distribution system to help combat a trailer with a heavy tongue. In order to choose the correct weight distribution system you will need to find the total tongue weight of your towing setup which is the loaded ready...

  • Recommended Weight Distribution System For 2018 Toyota Sequoia Towing Apex Trailer By Coachman
    In my experience the fully loaded tongue weight (TW) can be as much as 10 to 15 percent of the gross trailer weight. This number includes both the loaded tongue weight of your trailer, along with any added cargo weight coming from behind the rear axle of the tow vehicle. Ideally, this number should fall somewhere near the middle of the operating range on the system you choose. Because of that we will want to make sure we select a system that is rated to handle between 600 to 900 lbs of...

  • Blue Ox or Equal-I-Zer Weight Distribution System for AirStream Trailer
    In general people much prefer the Equal-I-Zer weight distribution systems over the Blue Ox setups. Based on that I would recommend the part # EQ37100ET. Equal-I-Zer systems are typically considered to be the "Gold Standard" in weight distribution setups based on how well they work. Blue Ox systems are bad by any means but some have issues with the chain hanger setups.

  • Can a 2008 Toyota Highlander Safely Tow a Dutchmen Kodiak 235
    Since your 2008 Toyota Highlander has a 5,000 lb trailer towing weight capacity you should be okay towing your Dutchmen Kodiak 235. If you were going to have the water tanks filled then that would be a problem. Using a Weight Distribution (WD) system and making sure you stay at least 80 lbs away from the weight capacity of your Highlander is a great idea as well. I do recommend making sure that you get the correct WD system for your towing application though. You want to make sure your...

  • How are Equalizer Weight Distribution Systems Adjusted
    The Equalizer Weight Distribution system part # EQ37100ET that came with your camper is one of the nicest systems on the market. It can be adjusted to level your SUV and would be a much better solution than suspension enhancement. The goal with an Equalizer weight distribution system is to get the distance from the ground to the wheel well half way back to the unloaded height when compared to the height of the vehicle with trailer connected. So if the distance was 30 inches unloaded and...

  • Equalizer or Curt Weight Distribution System Recommendation for Tongue Weight of 800 lbs Loaded
    Hands down the Equalizer setup would be what I recommend. The Curt TruTrack will work but we have seen a couple situations where the L-brackets of the kit ended up bending and because of that I wouldn't want to recommend them for you since I would hate for that to happen to you or anybody else. The Equalizer Kit part # EQ37100ET that you referenced would be exactly what I would recommend for you. It also comes with a hitch ball already so it would be all you need.

  • What Should Ball Height Be When Using Weight Distribution System
    You want to tow your trailer with the towing system as level as possible. You can count on up to about 1-1/2 inches of squat when you hook the trailer up so you can adjust your ball height so that it is about an inch or so to compensate for the squat when the trailer is connected.

  • Recommended Weight Distribution System for 2014 Chevrolet Tahoe and Winnebago Micro Minnie 2106DS
    My favorite weight distribution system is the Equal-I-zer Weight Distribution System with 4-Point Sway Control, like # EQ37100ET. Equal-I-zer has been in the weight distribution industry for many years and has a great reputation. I really like their weight distribution (WD) system because it will bolt around your trailer frame, rather than requiring you to drill into the frame and because the system is simpler to hitch up than a system with chains and cams. This system uses steel on steel...

  • Do Any Parts of Equal-I-zer Weight Distribution System Need to Be Removed from Trailer to Back Up
    The Equal-I-zer Weight Distribution System # EQ37100ET that you referenced can remain installed on the trailer while you back your trailer up. Ideally, with the system installed you will not need to make sharp turns while backing. I recommend removing the spring bars if you need to back your trailer into a tight space. Creating a sharp angle while backing with the weight distribution system hooked up will put unnecessary stress on the spring bar arms. Removing the spring bars while you...

  • Troubleshooting Installation of Equal-i-zer 10K Weight Distribution System EQ37100ET
    Thank you for your purchase of the Equal-i-zer 10K Weight Distribution System # EQ37100ET. My contact at Equal-i-zer said that when the head unit is powder-coated the bar sockets are already in place, so it is quite possible that they could stick due to the powder coat acting a bit like glue. What you can do is loosen the nuts that hold the sockets; these are torqued at the factory to 100-ft-lbs to allow them to wear in well during the first few trips. Loosening these to 65-ft-lbs (but...

  • Recommendations to Remedy Slight Sway with Equal-i-zer Weight Distribution System Installed
    If you are still experiencing some sway when using your Equal-i-zer Weight Distribution System such as the # EQ37100ET, there are a couple of things you can adjust on your setup to try and improve these conditions. First, lingering sway issues can be an indication of there not being enough weight distribution with the hitch. To remedy this, you will follow the "under-adjustment" guidelines in the installation manual. You will need to add more weight distribution force to the hitch by...

  • What is the Correct Weight Distribution System for a 6,500 lb Loaded Trailer?
    The short answer to your question is that yes, the Equal-i-zer, # EQ37100ET, would be a very good choice for you. The most important factor in determining which weight distribution system you should use is tongue weight, which should be 10-15 percent of your gross trailer weight (GTW) plus the weight of whatever cargo you have sitting behind the rear axle of your 2010 Chevy Suburban. For example, if your Jayco is loaded to max weight at 6,500 lbs, with a tongue weight of 650 lbs, and you...

  • Choosing the Correct Weight Distribution System
    Before purchasing a weight distribution system you'll want to make sure the trailer hitch receiver on your 1969 Buick Electra is rated for weight distribution. If it is then you'll need to find the trailer's loaded and ready to tow tongue weight to choose the correct system. Once you have the trailer's loaded tongue weight, add it to the amount of weight you add behind the Electra's rear axle. Then choose an appropriately rated system. For example, the Equal-I-zer # EQ37100ET is rated...
