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.
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.
Head Tilt Adjustment
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
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.
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.
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.

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.

I have been hesitant to review this product as I have had several issues with it....not necessarily the product itself, but my use and application. To start out, I should have used a different drop down hitch. The one that came with the unit does not allow the ball to sit low enough for the trailer to sit level once everything is set. Get the right amount of weight transfer and the nose of the trailer sits high which has a negative impact on towing. Less weight transfer for a level trailer means to more truck nose lift, dangerous sway, dangerous driving. The worst part is that if I had been aware and asked to change the hitch, it might have only cost me 10-20 dollars. Now I need to purchase a new hitch with a bigger drop, which will cost me around 150 bucks. I do believe that this will make a big difference. As I have gotten the setup closer to correct, it does seem to work well. I do however feel that the teflon plastic slide pads for the L brackets would be a worthwhile investment as it is noisy when making slow speed turns, which can be dis-concerting57823
