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.

Today, were gonna install the Equal-i-zer Sway Control Hitch part number EQ90-00-1200.First thing Im gonna do for our install is go ahead and attach your hitch bolt to the head assembly. And check your instructions for your shank distance. Were gonna install our hitch ball, lock washer and nut, go ahead and tighten it down. To install the hitch ball, what you gotta do is actually take the sockets where our spring bars go into and spread them apart. That way, you can get your socket inside. If you dont do that, its gonna be impossible to get the socket in there.
Then Ill go ahead and snug the bolt down and torque it down as specified in the instructions.Well go ahead and install the shank into our receiver hitch and install the hitch pin. Alright, next thing you wanna do is go ahead and go to your trailer and make sure its on level ground. I have the trailer sitting in level as best as possible and we wanna measure from the top of the coupler down to the ground. So its like 20 inches. So, when we set our head assembly onto our shank, we wanna measure that as close as possible.Ok, and before we install our head assembly, we need to place this washer assembly right here in that hole and that controls the tilt of the head.
Now, depending on the vehicle youre working with, it depends on how many washers youre using. More washers will tilt back the ball toward the trailer. Less washers will bring the ball close to the tow pin. Were gonna start off with five and try our initial judgment from there and see how it works.If were sure of our measurement, well go ahead and install the rest of our hardware. Use flat washers, lock washers and nut.
Alright, well go ahead and tilt our assembly up and theres a screw on the bottom that we need to adjust to take up the slack right here.Alright, well go ahead and turn our attention to the trailer. Once again, well install our frame brackets. We have one installed already right here. To give you a reference, the measurement were gonna use is from the center of the hitch ball is gonna be 32 inches to the center of our bracket. Now, if you have objects on your ton of the trailer that covers up that spot, you can move it in and out as needed and see the instructions for that distance.Our bracket consists three pieces of hardware.
Our first bracket with the short oval on one side is gonna get two of the short hex bolts just like that. Were gonna take our long bolt, well flip it over and put our long bolt through here, set that on the trailer, lock washer and nut. And then back to the other side and put our bolt as close as possible to the bottom of the frame. Were gonna take our bracket and for our initial setup, were gonna put it right in the middle. We may have to adjust it up or down. Well just try it out first and well install our two nylon lock nuts.Once were sure of our placement of our bracket, these two bolts here, were gonna tighten down and torque down as specified in the instructions.Alright, well go ahead and install our spring bar with the sticker facing out. This cutout will hit the bolt on the inside here. Well slide it into place then our pin then our clip. Were done with the driver side, lets go ahead to the passenger side and repeat the same process.With our spring bars installed, lets go ahead and back the truck onto the trailer and connect up. Okay, now what well do is go ahead and lock the coupler up to the ball and well go ahead and pick up the truck and trailer with the jack so it makes it easier to install the spring bar to the frame brackets.Alright, now were gonna take our spring bars and slide them onto the top part of our frame bracket. And put a pin that helps retain it in place and a clip on the bottom. With driver side down, well do the same thing on the passenger side. Go ahead and double-check our dimensions. From the center of our pin here to the outside edge, the absolute minimum should be three inches and were at 3 . Looks like were in good shape, lets go ahead and lower our truck and trailer and see how it sits.Alright, lets start our initial setup. Well go ahead and raise the truck and trailer once more to take the tension off the spring bars, get them out of the way and well adjust the frame brackets. Since we raised it up, we kinda lost some room to the side of the bar end but the kit does come with a tool that help you do that. You just need to last it a little bit over just like so.Alright, our driver side is done, repeat the same process over the passenger side. Alright, well go ahead and lower it one more time and check out our measurements with our truck and trailer.To increase our force to pick up our tongue load, we can go ahead and add one more washer to the head assembly and tilt it back more, try it again. If that doesnt work, well go ahead and raise our bracket one more hole up.Once were satisfied with our adjustment, well go ahead and torque down the last of our bolts.And thatll finish our install for part number EQ900-00-1200.
