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 (sold separately) 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.

Hello neighbors and friends, Steven here again with etrailer.com. Today we're talking weight distribution and specifically our Equal-i-zer Weight Distribution System. It's a four point sway control with no shank and no ball included, and it's rated at 6,000 pounds towing capacity and a max of 600 pounds tongue weight. So folks, why weight distribution What is weight distribution Well, pretty simply in a nutshell, weight distribution, just like the name sounds, evenly distributes weight over your axles of the tow vehicle and the vehicle, camper, tow or whatever you're towing behind it and gets it back up to level. So a lot of times if you're squatting in the rear, you're taking pressure off the front tires, your headlights are pointing up in the sky, not a safe scenario. Weight distribution will help get you back level, put weight back on the front tires, keep those headlights down, pointing safe.
Now that being said, there are many different options out there. You've got some with lift chains, those kind of things, extra bars on the top for the sway control part, all that. This brand, this unit does not require any of that. It's no drilling, it's simple clamp on brackets that can be adjusted along the length of the frame between 27 to 32 inches from the center of that ball back on the side. Now these brackets that come with it, keep the spring bars in place and give you a nice rigid system and it's gonna hold the trailer in line and again, there's no liftings or anything needed.
It's gonna be a steel on steel friction design. It's gonna minimize the sway that's caused by winds, curvy roads, certain maneuvers and driving, that kind of stuff. Now the unique design here makes this system compatible with surge type brake actuators as well. So these spring bars, the very heavy duty, they're 36' long, 1-1/4" by 1-1/4" square thick tubing, or not tubing rather, it's solid and they're gonna flex appropriately over the uneven terrain, give you a nice controlled even ride without the balance and all that kind of stuff. They are made of a chromoly steel for much, much superior dexterity and spring, everything's been dipped, powder coated, and it's gonna give you a nice corrosion resistant finish.
So you've got everything set up. Your lift brackets are mounted to the trailer frame, which again, you can have a max of six inches of trailer frame height. Just keep that in mind. You put the bar in, you put the tool under the bar and the lift tool here, the top point here goes into the square hole. You push the bar up and over into place and then you put this L retainer pin right on top of it.
Push the clip down and you're on your way. So there's that bracket system close up. That square tube steel bar is gonna be in between there. Again, that simply lifts up and comes out whenever you're not using it and it goes down. These are replacement parts as well. I recommend you buying a couple. A lot of people, unfortunately, just forget 'em or lose 'em sometimes if they sit 'em on a bumper and forget about 'em. So keep that in mind. Now one thing to point out also is where that bar sits on that L bracket and under the bar and around the bar where it's, you know, moving when you're turning corners, over time, it's probably gonna wear down that coating. That's perfectly normal, it's okay. Again, it's a metal on metal, steel on steel friction system. So you want friction. Now coming over to the head unit here again, the shank is sold separately. You can pick that out here at etrailer.com. Maybe you have a lifted truck or vehicle and you need a super big drop or maybe you need a certain size. That's why this particular one does not come with the shank. The way you get the right one you need for your specific setup, the top bolt here can go in and out. As you can see it's an oval hole there or oblong hole, this head can tilt up or down. That's why that oblong hole lets you do that. And then you got a stack of washers and what I call a head pin here, it's smooth, smooth on that side. There's a hole in the back of the head unit. You put the number of washers that you need for your specific application. You put that in the hole. Then once you put your shank in here and tighten everything down the right angle, it's squeezing that together and holding that into place at the right angle. So again, check the manufacturer instructions when you're installing your system and setting it up the first time. That'll let you know what you need to do there. The square retainer part here, the spring bar slides into that. It's got a standard pin and clip that retains it. There's the one on that side over there in place. So that's how that works. The ball again is sold separately. There's three sizes out there, 1-7/8", 2" and 2-5/16" balls. And you need a 1-1/4" diameter shank that's no longer than 2-3/8" long to fit in here correctly. So folks, gone over a lot of different things here. A lot of information, made in the US, limited lifetime warranty. Again, this is the Equal-i-zer Four Point Sway Control with no shank rated at 6,000 pounds. I'm Steven, thanks for your time, thanks for watching. Stay safe while you're towing.
