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.

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.Well made, heavy duty, easy to assemble, and install. Only one issue, the sockets that the sway bars go into are virtually immovable. I had to loosen the bolts and beat on them with a rubber mallet to get them to move (they are supposed to move freely). I contacted the manufacturer directly via their customer service, and was informed that there is a 4 trip break-in period and that “eventually” the sockets will move easier. This disclaimer should be noted in the advertisement for this hitch.
I'm sure it's a good hitch. However the description as well as etrailer chat support told me the hitch ball would come installed and torqued on the shank but that is not true. Now I have to find and pay someone to torque this ball to 450ft lbs or I have to buy more tools.

The hitch works amazing but still was annoying the product description is not accurate. It’s still the best hitch you can get.

E trailer had the product and was very quick on the delivery to my home. This 1600 lb Equal-I-zer hitch is well made and I expect it will perform well with towing our 36’ travel trailer. Setting it up was straight forward and I look to taking it out on the road.

The 1600lb Equal-i-zer carries the hitch weigh much better. Feels secure and quiet.
Excellent quality and straight forward installation. Only issue was obtaining the required torque with standard equipment. It’s heavy but does the job.

Still pleased. Have towed using it well over 10,000 miles without a problem. The bars are heavy but rugged keeping me in shape. Lost a retaining clip somewhere in Canada on a trip but purchased 2 new ones so I’d have a spare just in case it happens again. Highly recommend this product.
I have yet to install my hitch ,however shipping was exceptionally quick. All items for the hitch were in excellent condition.
thanks

Had a 10k equalizer WDS for 8k Jayco, worked well cross country. Needed heavier WDS for new travel trailer, so went with Equalizer again. Should treat us well on trip to Disney World.
The experience of ordering this hitch from Etrailer.com was great! Very helpful and professional people. I have had the Equalizer hitch previously. I upgraded to a HD truck and needed a new receiver size, as well as going with a higher load capacity of 16k lbs. These are great weight distribution hitches in every way.
This is Amazing! Works really well! Gotta grease it a lot at all the moving parts before you roll with it. If you don’t it makes horrible noises. That’s my only issue with it. And if you could get more tongue weight too! That would be Awesome! But can’t have your cake and eat it too! Thanks
It's works great. Have a 38' trailer with a dry tongue weight of 1,000 lb. Add battery propane and all the stuff in the trailer. I needed a heavy duty hitch with a two and a half inch shake. My old distribution hitch wasn't cutting it. I would get front end Rock like we were in a boat going over wake. The equalizer hitch eliminated the bounce and I have zero sway issues

Oh my goodness! I will have our customer service team reach out to you about this right away!
Works better than I expected
Product is great. The box it came in needs to be heavier cardboard, it was busted open. I hope everything is there and nothing fell out.
This W/D hitch is a monster. Well built heavy duty in every way. I can not wait to use it.
Terrific customer service, quick and easy transaction. Hitch arrived as expected without any issues. Easy to follow instructions and setup.
The unit is amazing. The shipping of the product is not the best. It gets a little scratch up when it gets sent out. Some thing happen with other products I purchased.

Still loving the product.
The Equilizer hitch installation instructions were easy to follow and the unit was easy to install. The only thing that I think would be better is if the hitch ball was installed at the factory or the specialty socket needed was priced more reasonably. I don’t have a store near me that can install the hitch ball. I was very happy with the service I received from Jamie S. To help expedite my order. She went out of her way to make sure my order was shipped out and she followed up letting me know when it shipped.
Great product easy to install works gre at
I've only towed with it twice but it seems like it is exactly what I needed. It was on backorder when I brought my new toy hauler home with an old, fairly lame hitch. Fortunately it was a short distance but the sway was quite unnerving.
The toy hauler tows way better with this hitch. If I have the sidexside inside the hauler I still get a little sway under some conditions.
The hitch is working great. Our previous hitch could not transfer enough weight to the front of our tow vehicle. After a few minor adjustments our trailer is now towing great!
Ordered replacecnt hitch after discovering my existing hitch had a bent shaft. They were very efficient by shipping hitch that day and delivery on the second day. Great customer service
All the products that I have ordered have been delivered promptly and met my expectations. Everyone I’ve spoken to at etrailer for assistance have been very helpful and knowledgeable.
I’ve been pleased and would highly recommend etrailer.
