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.

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. We have also found that the Powerbuilt 1-78 Inch Thin Walled Socket, part # ALL643216, works well with the Equal-i-zer system.

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.

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
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



by:

This hitch, after professional adjustment, tamed my trailer sway on our 27’ Coachman Freedom Express and leveled out our F150 as designed!
No white knuckle driving, highly recommend this hitch.
Easy mount and dismount of trailer on hitch and friction bars by following appropriate instructions.

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"



by:

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!



by:

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.

My wife and I installed the Equal-i-zer (10,000/1,000) without too much difficulty. The instructions are written in easy to understand steps. Measuring actual weight distribution was a long and iterative process, but was worth the effort to get a well balanced truck/trailer system. We started by loading our truck with the heavy stuff to closely match a typical camping trip. It took us several iterations of adjusting the bracket position and changing shank angle (changed from 6 washers to 4) to get distribution within specs. We also adjusted the hitch head height position on shank to level trailer. Our primary difficulty was loosening the socket bolts so sockets and spring bars could rotate. Instructions did not specify the 15/16" socket size needed to loosen bolts. We purchased the socket and used a 2' breaking bar which loosened bolts enough so bars could move to break the paint. We then tightened them back to specified >60ft-lb torque and greased as specified. It would be an improvement if manufacturer did this prior to shipping.

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



by:

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



by:

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...

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.



by:

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.

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



by:

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!



by:

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!



by:

This is my second Egualizer for a different truck. My original one is over 10 years old and works great on my SUV. Use it on my 28’ Airstream. Wouldn’t tow without it. E trailer is the way to go.



by:

Easy to install and use. Goof-proof. Significantly better sway control than the previous hitch I had. . . .but nearby big trucks are still noticeable. Glad I bought it.



by:

After owning the equalizer hitch for a year now I have zero complaints! Works like a charm pulling 10k lbs.

See what our Experts say about this Equal-i-zer Weight Distribution Hitch

  • 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...

  • Can Equalizer Frame Brackets Be Placed Only 25-1/2 Back From The Ball?
    While it may be possible to install the spring bars with the brackets at 25-1/2", this is going to have a negative effect on the performance of the Equalizer # EQ37100ET weight distribution hitch. The spring bars need to be allowed to flex, and positioning the brackets too close to the ball will not allow the bars to flex appropriately. We do not recommend installing the brackets outside of the specified range. It may not necessarily be unsafe, but you likely will not get the results you...

    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.

  • Correct Equal-i-zer Hitch for Flagstaff Micro Lite 21DS
    The Equal-i-zer Weight Distribution System w/ 4-Point Sway Control part # EQ37100ET is the perfect option for a Flagstaff Micro Lite 21DS so that is what I recommend. The trailer while fully loaded will still be well within the tongue and trailer weight range of the system and that is what makes it a perfect option. It sounds like you have already done quite a bit of research since you have found the best hitch. I am fully confident you will be happy with the Equal-i-zer and glad you choose...

  • How To Setup Weight Distribution Hitch On Vehicle With Factory Air Suspension
    When using a weight distribution hitch on a vehicle with factor air suspension like what your Tahoe has, it is ideal to disable the system and let the weight distribution hitch do the work. This may require pulling a fuse like you mentioned, but I recommend checking your owner's manual to see if there is another way to temporarily disable the system. If you are unable to disable the system you can setup the hitch after hooking up your trailer and letting the air suspension level the best...

  • 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...

  • Best West Distribution System for a Heartland NorthTrail 28RKDS
    The Blue Ox SwayPro Weight Distribution System is a good option and will work well to both reduce vehicle sag and prevent trailer sway. However, I recommend the Equal-i-zer Weight Distribution System which has four point sway control and will do a much better job of minimizing trailer sway in comparison to the Blue Ox system. In order to choose the correct system you will need to add the loaded ready to tow tongue weight of your trailer by any cargo stored behind the rear axle of the tow...

  • Can Air Bag Suspension be Used with Andersen Weight Distribution Systems
    When using air suspension enhancement with a weight distribution system like you mentioned you will want to first decide how much air you want to put in the bags and then set the weight distribution system up after that. This will give you the best overall towing experience. From then on out you'll need to use the same air pressure in the bags when towing and using the system. I'd start with air pressure that gets you about half-way to level and then use the WD system to finish the leveling...

  • 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. What we recommend doing when installing the weight distribution system is first hooking your trailer up to the Jeep (with it fully loaded) and letting the Jeep level itself.

  • Recommended Equal-I-Zer WD Hitch to Fit a 2017 Ford F-250 Super Duty
    When trying to decide on a proper weight distribution (WD) system for your towing rig, you will need to know the total tongue weight (TTW) of your set-up. The total tongue weight will be a fully loaded ready to tow trailer, plus any weight located behind the rear axle of your Ford F-250 . The best solution will be to use a system where your total tongue weight will fall in between the WD system's tongue weight range. I have attached an article that will explain how to find the TTW of your...

  • Anti-Rattle Device for Weight Distribution System
    There really should not be any movement if your Equal-i-zer hitch such as # EQ37100ET is properly set up so I recommend ensuring that you have both the properly rated system and one that has been installed correctly. There is not an immobilizer specifically designed for Equal-i-zer systems.

  • Weight Distribution Recommendation for 2020 Jayco 264BH
    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. 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. I looked up the GVWR of your 2020 Jayco 264BH and at most it would weigh 6,000 lbs so for a weight distribution system...

  • 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...

  • 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.
