The Equal-i-zer has a reputation as strong as its American-made steel. We love this hitch's solid build quality and that it helps to proactively stop trailer sway instead of just dampening it after it starts. Ball and shank included.

Pro Tip: Before you invest in a weight distribution hitch, make sure your cargo is evenly loaded in your trailer to keep the weight balanced. If you still have a hard time even after balancing your tongue weight, a weight distribution hitch should help.
Does it seem like no matter where you go, you meet someone who owns - and has vouched for - the Equal-i-zer weight distribution system? There's one really good reason for this: the Equal-i-zer's build quality is second to none. Many companies have tried to imitate it, and they just can't. Sure, they might preempt trailer sway just as the Equal-i-zer does. But for over 75 years, using American-made steel, the Equal-i-zer's unique design has kept haulers from white knuckling the steering wheel.
Let's talk about how it does that. Essentially, this system is built to hold your trailer in place both at the connection point and along the trailer's frame. Inside the system head, the trunnions are tightly pinched in place to create resistance. Because the trunnions are held in so tightly in the head, with the help of some torqued socket bolts, once the spring bars are installed, they won't be able to move side to side without a ton of resistance. At the other end of the bars, frame-mounted L-brackets provide a rigid surface that also helps prevent any unwanted movement. Just like the tension in the head, these brackets help hold your trailer in place. All of this tension throughout the system helps to create a rigid steel-on-steel setup that keeps your trailer in line and your ride level.
If a particularly strong wind gust crosses your path and your trailer starts to get off track despite the Equal-i-zer's firm hold, the steel-on-steel friction of the bars on their brackets will stop the bars from moving, and ultimately dampen any remaining trailer sway. Between the 2 friction points inside the system head and the 2 that you get at the L-brackets, the Equal-i-zer creates up to 3 times more side-to-side resistance than other weight distribution systems, or the equivalent of adding 8 friction sway bars. And because you won't need any of those add-on sway bars, you'll actually be able to use this system when towing in the rain or over gravel roads, and you can back up without having to disconnect a thing!
Because the steel-on-steel friction between the bars and brackets is noisy, don't be alarmed if you hear a lot of banging, creaking, and grinding. It's just the system working to correct sway in much the same way that locomotives keep multi-ton railcars from swaying. If the noise becomes too much of an issue for you, there are a few things you can do to address it. You could get some of Equal-i-zer's replaceable nylon sway bracket jackets (EQ95-01-5150). Or you could lubricate any friction points with their high-performance lubricant (EQ91-00-4250). But keep in mind that cutting down on noise isn't the only thing this will do. These quick fixes will limit the system's ability to prevent sway, too.
If you're determined to have a rock-solid towing setup without making any compromises, and you have to have an an American-made weight distribution hitch, and noise is kind of a deal-breaker for you, you may want to spring for the B&W Continuum or the Blue Ox SwayPro instead.
Once you've got the hitch ball torqued down, you'll have to adjust the tilt of the head to ensure proper leverage. To do this, simply slide washers onto the spacer rivet and insert it into the head assembly. Once the spacer is in place, tighten the shank bolts to secure the head to the shank. To check if your truck and trailer are level, you'll need to hook up and release your tongue jack. If you find that the rear of your truck is still sagging, add washers to increase leverage. If it looks like too much weight has been taken off your truck's rear axle and is sitting on your front axle, try removing a few washers.
While the washer-stacking method allows you to fine-tune the setup at the time of installation, it's going to require some patience. It can be time consuming because, if you don't get everything right the first time (which, you probably won't), you'll have to take the head unit apart to adjust the washers. You might have to raise or lower the L-brackets too to get the tension just right, and that's a bit of a pain also. Not to mention that you might have to repeat this process if your tongue weight changes or if you swap out your tow vehicle.
Pro Tip: For a step-by-step guide on how to fully install the Equal-i-zer, check out our videos at the top of this page. Our installers even have some advice to offer on measuring your vehicle's squat.
Your tongue weight is the first thing you need to know when figuring out which weight distribution system you need. Most people think that if they get the highest-rated system possible, it'll be smooth sailing. But actually, this will create a rigid ride and a bouncing trailer. On the other hand, if the system isn't strong enough, it won't be able to distribute the weight properly, making it virtually useless.
Once you know your trailer's tongue weight, add it to the weight of the cargo behind the rear axle of your tow vehicle. Then just choose a weight distribution system rated for that combined tongue weight.

Perfect fit and function and easy to install. The ordering process was very simple and the item arrived in perfect condition and within about three days of ordering. The thin wall socket issue was solved simply by going to Harbor Freight and picking up a 3/4” drive SAE socket set that went up to a 2” socket for less than the price of the socket alone and it came with the ratchet necessary to tighten it. My tent camper and tow vehicle are perfectly level. Haven’t taken it out on a trip yet but I know it will ride much better than before as the front end was at least 3” higher than the back prior to putting on Equilizer Weight Distribution System. Thanks for carrying suck a great product.
My forst equalizer hitch is a winner. Way easier to use than my friend's version with the chains ... Easy setup and works great on my 4,000 lb. camper. Almost completely eliminated sway from passing trucks, etc. Can back up without unhooking which is great.
Installed myself and spent a lot of time adjusting the torsion and test driving. Very pleased with the firmness and stability of the 4000 lb. trailer. There are periods when I hear some squeaking in back, but retightening all the hitch bolts seems to alleviate most of the noise.
Spoke with a knowledgable gal at etrailer.com and she convinced me this is the best hitch to use. I ordered it on Sunday evening, it arrived on Tuesday and was in perfect condition. Hitch took 3 hours to install. A $12.00 (regular wall thickness) 1-7/8 was needed from [on-line retailer]. Hitch works very well. So glad I didn’t buy a cheap hitch. This one does everything well. Highly recommend etrailer.com, EQ37060ET Hitch and 3/4 Drive 12 pt. Socket with (3/4 to 1/2 adapter) socket. I will continue to do business with etrailer.com.
I just drove from VT to PA to SC to MD to CT and back to VT, close to 3K miles and this weight distribution/sway control worked great ( I think it did, my first sway bar). Not sure on the effectiveness of the weight distribution as I was pulling with 2018 Jeep G.C. and that SUV does not sag under 500 lbs tongue weight. You can feel that you are pulling a trailer when a semi passes you going over 80 miles an hour, or when you get hit with a side wind on a bridge, but all other conditions are fine (e.g. passing semi truck or normal side wind). Easy to back up into any place. On advice to everybody, keep it lubricated, if you don't, enjoy screeching noise with every turn :). Happy towing.
Excellent! This has been a great product for me. As a first time travel trailer owner I was concerned with the safety of towing a trailer and concerned with controlling swaying of the trailer and tow vehicle. I had towed a rental trailer once and got a good scare when it started swaying when I tried to pass a transport truck. I set this up using the provided instructions and all worked great. Tow vehicle is level and no swaying in traffic or in very windy conditions. I even had to change tow vehicles in the middle of an extended trip and the conversion to the new vehicle was very easy even though I was "on the road". I just followed the instructions again and all worked very well.
I highly recommend this unit.

Great product. Sway and bounce are eliminated.
I can't speak on the hitch itself because I was never able to use it, but I hear great things. However, I want to save someone else the hassle here, so if your camper trailer has a propane or battery platform on the top side of the V hitch/tongue - you may need to do some serious modifications to put the brackets in the correct position. Check the manual and measure before you order!
What can I say...the first time my wife pulled our trailer there was a wreck ahead of us. The tractor trailer next to us was smoking his tires while my wife had to lock up the brakes and our trailer stayed straight behind us.
This unit has made towing a breeze and my wife has no problems getting behind the wheel.
The Equalizer has been a great hitch. I needed the sway control more than the weight distribution in windy Kansas, and this hitch virtually eliminated sway. The weight distribution does alleviate bouncing and makes me feel completely in control of the trailer. I bought the pads to control noise, and I’m glad I did. No complaints.
The only downside is that the hitch is heavy and bulky. I’ve yet to find a simple and clean place to store it.
We purchased a 19 foot RV travel trailer last year, and even though this may be considered a smaller trailer, it was considerably bigger and heavier than the pop up trailers we have used for the last 20 years, so a new venture for us.
I knew I wanted a weight distribution and sway control hitch, but was not sure which to buy. So, I posted the question on this site, and this hitch was the one recommendation by this site's representative.
The quality of the hitch and hardware is excellent, and the instructions for installation and adjustment were very clear and easy to understand.
So far, we have pulled the trailer on several trips from East Tennessee to central WV.
On the long stretches of freeway driving, often with heavy traffic, and on the steep grades, and curves going over the mountains, I was very pleased with the performance of this hitch. The hitch provides excellent sway control, and with proper adjustment there are absolutely no steering or handling issues with the tow vehicle.
The guys on this site know their stuff!
Would have been 5star.
The hitch it well built and strong. I was told by the E-Trailer operator that it came with a 2in ball already installed. Come to find out it doesn’t. This is frustrating now our trip is going to be postponed or canceled. Apparently you need a special sockoand short thread 2in ball. Bummer

I really couldn't figure out how this device was going to help with towing our 19' RV. From an engineering standpoint I'm still baffled. The RV center applied it to our new Coachmen Apex Nano so I don't have the experience of installing it myself. They made it seem simple. The only "special" tool they used was a high-torque air gun to secure the ball. I was seriously concerned that the weight of the RV (3,500 Lbs.) would try to control my Dodge Ram ProMaster 2500 van. While the van could certainly use more towing power, I was blown away at how smoothly it towed the RV. I expected very little and was pleasantly surprised by the performance of this system. The first year I put 600 miles on our RV and was never once disappointed or regretful of my purchase. It's really nice that reversing the vehicle has no adverse effect. Some stabilizers won't allow you to reverse. The cost of the unit was a little shocking at first and you may ask yourself where all the money is with just a few heavy metal pieces. The money is in the magic of the performance. Spend the extra dollars on the best, it's worth the peace of mind while towing.
Hauling 21 ft. travel trailer. Big difference in how it tows with this hitch as opposed to hauling without an equalizer hitch. Highly recommend this hitch, none better. I have hauled around 4000 miles, mostly mountain roads in the west, with some good winds and my trailer is rock solid with this hitch. Do not tow without a equalizer hitch and if you want the best, get this one. Excellent customer service from e-trailer on this and everything I order from them. About to order rear stabilizer coupler and pins to fix electric stabilizer from them.
The Equalizer weight distribution system works very well. Sway and bounce are eliminated. Unfortunately, the unit does not come with the plastic sway bracket jackets (Item # EQ95-01-5150) so add those when ordering. The recommended grease (part # 91-00-4250) is also not included but any quality bearing grease will suffice. The plastic jackets eliminate a lot of the noise usually heard when turning, while also protecting the bars and brackets from wear & tear. The installation instructions are well written. Someone with average knowledge of tools should have no problem installing this unit by themselves. Locating a 1 7/8" thin wall socket and a torque wrench capable of 430 lbs to install the ball to the hitch head is the only real challenge. I ended up buying a large 3/4" socket set from Harbor Frieght. I used the long breaker bar from the set and a long pipe to get the ball nut tight, then my friendly local truck repair shop adjusted the torque to the proper specs using their obscenely expensive Snap-On brand monster torque wrench. It only cost me a round of coffee. After initial set up, attaching and removing the unit between truck and trailer is quick and easy. I recommend this item.
Entire order went very well except that I put the wrong address on my credit card information. Donna, from customer service, called and got everything cleared up and my order was shipped within hours. I havent used the hitch yet but it was all in excellent condition.

Installation went well and we have been towing our rv since with no problems at all. I have had no sway at all with the hitch.
One of the most important parts of this system is the Ball, so the customer should be asked for their Ball size and that should be what they send with the system, or they should specify you need to purchase the correct ball size with the system. Instead, they sent a 2" ball which I missed in the description of what comes with it, that's my fault. Now I have to search around for the correct Ball to fit my trailer and the system, and I'm stuck with a worthless 2" ball with a large shank that doesn't fit 90% of all ball shanks. I emailed Trailer about this and their reply was it comes with a 2" ball... not helpful.

If you need a slightly bigger size ball mount, you can change out the two inch ball for the two and five sixteenths ball mount part # EQ91-00-6100. To swap them out, you would need part # ALL643216.
Ever since we purchased this Weight distribution system, we have been on 7 trips with our travel trailer. Every trip the system far exceeded our expectation. The built quality is amazing and by the looks of it, it will last a lifetime if taken care off properly. We would recommend this system to anyone planning to tow their travel trailer and wants the peace of mind that a gust of wind or fast-moving tractor trailer is NOT going to have you take evasive maneuvers.

An year later and 18 trips in, the Equalizer weight distribution system is as good as it was on day one. You dont always get to see/feel it working but the confidence we have taking our trailer on highways knowing that this system is doing exactly what it should grows with every trip. The system is definitely worth considering for anyone who tows anything that is more than 2000 pounds in weight.
The new hitch allowed us to get our camper almost exactly level. It barely feels like we have something hooked to the truck. We get no wind pushing us around when trucks pass us on the interstate. It was easy to attach to our camper. Your shipment came in exactly when you said it would. Thank you very much for your good service and for the good hitch.

I have loved your hitches since 1995. We pulled a camper for 10 years without one and basically started avoiding the interstate highways because of what happened when trucks passed us. The guy at the place we stored our camper had a used Equilizer that we bought and used for 12 years. We got a new tow vehicle with a higher hitch and the old Equilizer was welded and could not be adjusted. Thats when we bought the new one. I watch people at the campgrounds wrestling with other hitches and I just calmly hook mine up and go. I hardly feel the camper behind us. You have a great product and I will use it till I cant camp any more.
I have been using my Equalizer weight distribution hitch for a year now. It truly is the best hitch I have ever used. Towing through high winds in eastern Oregon, Idaho and Wyoming our trailer (a 21 foot Escape) tracked perfect with no sway what-so-ever. Also there was one occasion that I had to make a very sudden stop to avoid a deer running in front of me. The trailer was rock solid, with no sway. Thank you Equalizer. It took a little time to set up the system properly, but, with a little help from a few friends it was easy. I found it important to have a local tire shop assist in torquing everything to the recommended specs. Great product and lots of good support from eTrailer.

The Equalizer hitch continues to work great. During our many camping trips throughout British Columbia, Montana and the Oregon Coast the hitch has kept our trailer in-line and we have had no swaying issues in some very heavy weather. Great product and well worth the money!
I towed my trailer out West in July. No problems on windy roads thanks to your product!
All products are great and as expected. One box was damaged in shipment due to the heavy nature of the parts. A smaller part fell out through a hole in box. George at etrailer got me a replacement part quickly with no issues.

Provides excellent sway control and load distribution for my camping trailer.
It was also easy to install and setup.
Love It Put over 5000 miles towing not one bit of trouble
4000 LB 21 RBS Livin Lite Pulled by 2015 Toyota Tacoma
Excellent product. This is my 2nd Equalizer hitch. First one was a 10,000lb I used on my 29ft Keystone Camper that was around 8500lbs loaded towing with an 04 F250. I now have a 6,000lb I am using on my 6x12 V-nose around 3500lbs with a 600lb tounge weight towing with a 2016 Tacoma. These hitches make a world of difference when towing & are pretty easy to setup. Especially after doing it once lol.
