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

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.

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!

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.

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.

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.

- EQ37100ET

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.

Ordered this product for the built in sway control. My last hitch required another device to achieve this, but I didn't care for the additional work when backing up or on wet surfaces. The order shipped quickly and arrived intact in 2 separate packages. The smaller of the two, contained the hitch shank and main body. It's heavy, so it was expected that the box would have a hole. The other larger package was sealed and intact. All parts were present. Setup was straightforward, documentation excellent. Particularly the places to annotate measurements. The manual was small but effective. The ball mounting requires a thin walled 1 7/8 socket. I didn't buy this, my RV dealer torqued my setup for nothing. Very satisfied with this hitch thus far. Will update when I have had a chance to put it through the motion.

The 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

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.

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.

- 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.

- EQ37100ET

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"

- EQ37100ET

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!

- EQ37100ET

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.

- EQ37100ET

I don’t write many reviews but this seems to be a pretty good product. Instructions are not bad but you must tailor to your particular tow vehicle and trailer. My weight distribution works fine. Finding someone with 3/4” drive torque wrench is not easy, but I got it done.

I have traveled about 5000 miles since installation with no problems. My son recently bought the same weight distribution hitch I have for his travel trailer and has had no problems.

First time trailer owner and took it out about 20 times this year during the "rona" since everyone was remote and California has great weather. Great system, easy to hook up, and an absolute for anyone running a trailer over a few thousand pounds

- EQ37100ET

Thank you Jesus for the Equalizer! It works great. The sway control is fantastic. Just be sure to take your time setting it up and getting all your measurements correct. Follow the instructions.

It’s been holding up very well. I apply some grease to the friction points occasionally and make sure the bolts are tight. I also take it off the truck when I am not towing the camper. No point in leaving out in the weather if I’m not using it. That’s the only maintenance I do to it.

This hitch is much more solid than the one I had. The installation was easy, including making fine adjustments. The feel of the trailer after the installation was firm with no bounce. I am very pleased.

- EQ37100ET

I have been searching high and low for this highly suggested hitch! I found it on etrailer and had a 10/10 experienced through the entire process! I will be ordering through them again as I bookmarked the website to be sure to remember!

Its been a year and we have been happy with the hitch system! Before the equalizer, we were white knuckling with the old style load levelers with our f350. Now we can drive with ease
Erin - 06/13/2020

- EQ37100ET

It's an excellent product. Almost eliminates all sway and balances the load on my truck. A little noisy, but If you keep it properly lubed it's not a bother. Haven't seen any that I like better. The torsion bars control but up and down where I would imagine a drop chain can only control one way. Con: There are a pain to hook up. You have to install bars, lift the back of your truck with your trailer jack, install the bars and then drop it back down. Around town , I don't install the bars. I did add the sway bracket jackets to reduce the noise some.

- EQ37100ET

I know the product is excellent and I followed the instructions on setting it up. I haven't taken a trip with the setup yet but I think it is going to work out just fine. I was worried when I saw the box that the hitch and shaft came in because parts were falling out of the box and I thought I might be missing something. Luckily everything was there. Not sure what UPS was doing to beat up the box so badly but it was a mess.

Works really good.
JAN J - 05/06/2020

- EQ37100ET

The good: It was easy to install. It works as stated. My 8000lb trailer rides very well with this hitch. I tow very close to my max capacity, but the hitch keeps the “rig” reasonably stable in wind and when being passed. The bad: The hitch is too heavy for the box is was shipped in and it arrived just as it was about to fall apart. There was considerable surface damage and scratches on some parts. The “wear in” on the hitch is extreme. After one use the hitch head wear surfaces were pitted and sharp. I used grease per the manual , but the surfaces were not flat to start. The head is difficult to handle with these dangerous sharp edges. Last, after 2 months, the brackets have rusted to the point where they need to be repainted. To summarize, the hitch works well, but I do not see this lasting many years. I missed the less expensive E2 hitch I used previously.

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.

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

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

  • Recommended Weight Distribution for Trailer With 1600 lbs of Tongue Weight
    Whew. That's one heavy trailer! As long as the trailer tongue weight won't exceed 1600 lbs, the # EQ64FR 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...

  • Weight Distribution Hitch With Sway for a 2021 Jayco Jay Flight SLX 267BHS Travel Trailer
    For your 2021 Jayco Jay Flight SLX 267BHS I recommend using the Equal-i-zer Weight Distribution System # EQ37100ET. This hitch offers weight distribution and sway control with no need to remove parts when backing up. You Jayco has 695lbs of tongue weight dry and when loaded you will probably see that number get closer to 900lbs. The Equal-i-zer is rated for up to 1,000lbs of tongue weight. If you are installing this hitch yourself you will need a 1-7/8" 12pt Thin Walled Socket # ALL643216...

  • Excessive Trailer Sway While Towing with Late Model Ford F-150 Using Sway Control
    I do have some things that you can adjust on the Equal-i-zer Weight Distribution System but I will say this is a common compliant with the late model Ford F-150's. The weight distribution system could very well be setup properly as well as the trailer loaded correctly but yet still have sway. I can't say exactly what causes this but I can say this is not uncommon and we hear this compliant quite often. I have heard some people that have the factory airbags have had success with turning...

  • Does Reese Weight Distribution Shank Fit Equal-i-zer Weight Distribution
    It sure does; weight distribution shanks are by and large universal, so long as they have the correct bolt hole diameter of 3/4" and spacing of 1-1/4", which the Reese shank you asked about does: - Reese Weight Distribution Shank for 2" Hitches # RP69FR Because it has the correct dimensions, it will absolutely work with your Equal-i-zer weight distribution hitch.

  • Fighting Sway From Wind With Light Weight Enclosed Cargo Trailer
    It seems like you've got a pretty good grasp on this! I will make one slight change or clarification to you- approximately 10-15% of the total loaded weight of the trailer is what you want as your tongue weight. It won't actually change the 60% that you want forward of the axle, and it's something that you'll likely want to purchase a tongue weight scale to make sure that you're not under/overloaded at the tongue. For this, I recommend using a ball mount scale like the Weigh Safe # WSUN-1...

  • Selecting Weight Distribution System 2015 Jayco 26RKS Travel Trailer
    Weight distribution/sway control systems like the Equal-i-zer 4-Point # EQ37100ET are not specific to a brand or model of trailer but selecting the right one is important for getting the most benefits they can provide in your towing setup. If you like you can click on the linked video which explains lots about WD systems. The key is knowing your fully-loaded trailer's actual tongue weight (TW) since that is what matters most. The ideal situation is that your total TW (which includes...

  • 2020 F-150 & Equal-i-zer Weight Distribution System w/ 4-Point Sway Control
    For what you have described I suggest the Equal-i-zer Weight Distribution System w/ 4-Point Sway Control # EQ37100ET. This is for a trailer tongue weight from 600 lbs to 1,000 lbs. If you have an estimated loaded trailer weight at 7,500 lbs. then I think you may be underestimating your tongue weight. A TW is generally speaking 10-15% of properly loaded trailer. This hitch has steel-on-steel friction to prevent and correct trailer sway in this unique weight distribution system. Sway control...

  • Missing Rivet From Equal-i-zer Weight Distribution System
    I spoke to the manufacturer of your Equal-i-zer Weight Distribution System # EQ37100ET. They said if you do not have the Spacer Rivet # EQ95-01-9450 that you would be able to use a bolt as a temporary replacement. You will want to be sure to check the tension on the Angle Set Bolt # EQ90-03-9700 frequently(every 100 miles) to ensure that it is tight and doesn't allow the hitch head to move as this could cause damage to the head.

  • Shank for Bigger Drop With Weight Distribution Hitch for 2 Inch Receiver
    Yes, you will need to set it up all over again for the different height of your new truck, just like you did initially. You can find out how to do this in the instruction manual of whichever hitch you currently have, like the Equal-i-zer Weight Distribution System with 4-Point Sway Control # EQ37100ET.

  • Does Weight Distribution System for 2008 Ford Explorer Increase Towing Capacity
    The GCWR is the total allowable weight of your fully loaded 2008 Ford Explorer and travel trailer so the hitch weight (tongue weight) would not factor into that. If you looked in your owner's manual and are sure that your GCWR is 15,000 lbs, that would be the total weight that your loaded vehicle and trailer could weigh; additionally, tongue weight does not factor into payload capacity, and a weight distribution system does not factor into the tongue weight. What you need to do is make...

  • Weight Distribution System That has Sway Control and is Quieter than Equalizer
    The Equalizer systems use friction in the head and bars to create the sway reduction. The problem is that friction can resonate and create some interesting noises. This system is known for working well but also for making noise. Other option that is similar and some argue is better is the Strait Line systems like the # RP66083. These don't mak the same noises but do sometimes make a loud pop around corners.

  • Recommended Weight Distribution with the Ford Anti Sway System
    The sway control system on your 2020 Ford Expedition is designed to help after the sway event starts. With that said I highly recommend going with a weight distribution system that helps to keep it from ever happening like one similar to the Equal-i-zer Weight Distribution System w/ 4-Point Sway Control part # EQ37100ET which is by far my favorite. When choosing a system you want one that has the tongue weight rating that is equal to the tongue weight plus anything behind the rear axle....

  • 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...

The install instructions are linked for you; please refer to page 9 to see the part concerning hitch ball installation.

  • Weight Distribution System Recommendation for 7,500 lb Travel Trailer
    The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow. This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached a help article on determining tongue weight for you to check out as well. You will want the loaded tongue weight of your setup to fall right in the middle of the tongue weight range of the system you use. If your trailer was loaded to it's...

  • Using Surge or Electric Brakes with A Weight Distribution Hitch
    The main difference between weight distribution that are compatible with surge brakes and systems that are not is the design of the the spring bars. The Equal-i-zer Weight Distribution System # EQ37100ET has straight spring bars that are designed to move back and forth in the frame clamps. These bars allow enough movement in the hitch to correctly activate a surge brake coupler. Typically, the chain and cam design weight distribution systems, like the Reese Strait-Line System # RP66084,...

    Sam, both the Blue Ox SwayPro part # BXW1000 and Equal-i-zer Weight Distribution System w/ 4-Point Sway Control part # EQ37100ET are great options. The Equal-i-zer Weight Distribution System w/ 4-Point Sway Control can be loud like you mentioned because of it's friction sway control however it is going to provide a much better towing experience than the Blue Ox because of it's 4 point friction contact. The 4 point friction sway control helps to keep the trailer in line to combat sway. The...

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

  • Fit Of Equal-i-zer Weight Distribution System On Aluminum-Frame V-Nose ATC Trailer
    Yes. The Equal-i-zer Weight Distribution System w/ 4-Point Sway Control - 10,000 lbs GTW, 1,000 lbs TW # EQ37100ET requires the sway control brackets be positioned between 27-32 inches back from center of coupler, so with your 29 inch measurement it will fit as long as the frame height is 6 inches or less. It is recommended to use the Thin Walled Socket for Equal-i-zer Hitches # EQ70-00-4800 to install the included hitch ball on this system.

  • 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...

    The Equal-i-zer Weight Distribution System part # EQ37100ET and Blue Ox SwayPro Weight Distribution System part # BXW1000 are both great options. However, in regards to combating trailer sway the edge has to go to the Equal-i-zer because it has true 4-Point sway control whereas Blue Ox really only has a 2-Point sway control system. The additional two points of contact means the system will be able to do a much better job of combating trailer sway. I have attached a photo for you that points...

  • Can AirLift Air Suspension System and Weight Distribution Be Used Together
    You can indeed use both an air suspension and weight distribution in tandem. We advise folks to air the bags to the desired level, then set up the weight distribution system according to the instructions. Not everybody agrees, some will state the other way around, but we've always recommended to do the bags first. An AirLift Load Lifter 5000 system like part number # AL57385 would work well for you. A compressor system, part # AL25592 is also available. A compressor system will allow...

  • Need Shank Like What Is Included With Equal-i-zer Weight Distribution Systems
    The shank that typically is included with an Equal-i-zer weight distribution system, if you purchase it with one is part # EQ90-02-4100 which will offer up to a 7 inch rise or a 3 inch drop. Since you have a 1-1/2 inch height difference between the trailer coupler and receiver height, the # EQ90-02-4100 would absolutely the the correct weight distributing shank for your needs.

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

  • Is it Possible to Use Too High Rated of a Weight Distribution System
    Yes, if you use a weight distribution system that is rated too high for the tongue weight of a trailer the ride quality will be incredibly stiff and harsh. You want to ideally pick a system that has a tongue weight range where your tongue weight falls right in the middle. The Equalizer Kit part # EQ37100ET has a tongue weight range of 600-1,000 lbs and would be ideal for you.

  • Comparing Equal-i-zer and Blue Ox Weight Distribution Systems With Sway Control
    Right off the bat the Equal-i-zer # EQ37100ET has an advantage because it has a larger Tongue Weight (TW) range of 600 lbs - 1,000 lbs as opposed to the 750 lbs - 1,000 lbs TW range of the Blue Ox # BXW1000. The flip side of that is if you get a heavier or lighter trailer then you would need to change out the whole Equal-i-zer Weight Distribution (WD) system whereas the Blue Ox systems use the same head so you would just need to swap out the bars. This is much more cost-effective than purchasing...

  • 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.
