Weight Distribution Diagram

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.



Selecting a Weight Distribution System

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.


Features of the Equal-i-zer

Head Tilt Adjustment

Controlling head tilt with traditional washer method

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

Installation of 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.


Equal-i-zer Hitch 4-Point Sway Control

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.


Points within the Equal-i-zer system where upward and downward forces interact to create rotational friction

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.

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.




by:

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




by:

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.




by:

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




by:

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.




by:

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.




by:

Very happy with this product. Function as advertised along with no performance or maintenance issues.




by:

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.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch


Great hitch system. Easy directions to mount and set up for my truck (F150) and Grand Design Imagine travel trailer. Hook up at camp site is much easier compared to my chain and bar system. New set up handles sway and is very stable when trucks and cars pass.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch


etrailer was great. Great service and quick and easy. The actual hitch itself was easy to install despite not having the clearest instructions and then difficult to get the sway bar socket to swivel. A lot of grinding metal and leftover burrs in the sockets making them hard to move even when the socket bolts and bush were loosened and all moving parts greased. That part was not machines well. Rest was. I filed and wire wheeled it and got them to move but still very stiff. But it works now and rides well. An hour and half job though took four hours.


Comments
It is possible that the weight distribution system could be over your tongue weight. Ideally your total TW will fall in the middle of the systems operating range. This ensures the system is stiff enough to provide the weight shift to your front axle, but without being so stiff that it causes weird handling from the trailer. If your actual total TW is 1200-1300-lbs then a system rated for between 1000- and 1400-lbs would be perfect. There are a couple of other possibilities that could be causing the grinding, however, we would need some more information.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch


Product is fine but shipping is horrible. Items arrived in boxes that were falling apart. UPS had to tape a whole box and parts were falling out when it arrived. Haven’t had a chance to check to see if everything is even in the box. Not acceptable.

I will have Customer Service reach out to you.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch


Took the sway away for the most part. Would be better if you could order it without the drop ball hitch (part that slips into receiver) since I had to get a longer one anyway for my setup.

Review from a similar 4-Point Sway Control in Weight Distribution Hitch


I rate this product "good" to alert potential users to an issue I face during installation of this Equal-i-zer hitch.

As I purchased this hitch, a 2 and 15/16" ball with a 1.25" shank stud and its nut were included. That nut requires a special 1 and 7/8" thin walled socket that slips down into a cavity where the shank stud protrudes and the nut screws on. The instructions state that socket is available at Equal-i-zer dealers. Such a socket WAS NOT AVAILABLE at any automotive parts store, car dealership, nor agricultural supply hardware I contacted in the small California town I was in. The nearest Equalizer dealer to me was over 100 miles distant, and I had planned to leave the day I began installation of the hitch. The instructions also state that a shim can be used if a 2 and 15/16" ball with a 1" shank stud and nut are used. That is the ball I already had on my truck and I was fortunate to find a properly sized shim at an agricultural supply hardware that I cut to length and used in my installation. I still needed a large socket and extension to tighten the nut because the nut was deeply recessed in the cavity. The box end wrench I normally used on the nut was of no avail; however, an automotive repair shop had such a socket and loaned it to me to complete the installation of the hitch. IF you are going to undertake the installation of this hitch yourself, then be aware of the need for either the special Equal-i-zer specified socket for the ball included, OR a 1.25" to 1" shim and a deep well socket for the smaller 1" shank stud and nut such as I used. Contact customer service at Equal-i-zer if you have questions in this regard BEFORE you purchase.

Having alerted you to the installation issue I faced, I now rate the product itself as EXCELLENT in performing the job it is intended to do when towing. Once I had the hitch installed, the instructions for making adjustments so it will perform as intended are clear. Along with the hitch I purchased a Sherline trailer tongue scale and that is an accessory I highly recommend.

I was towing a 2-axle car trailer loaded with a vehicle for a total tow load of 5500 lbs.
Using the tongue scale I adjusted my load so 10% was on the tongue. I was towing cross-country from California to Michigan with a 2010 Tacoma 4 x 4 rated with a 6500 lb towing capacity. I towed at 55-60 mph and had one incident that required immediate, heavy braking and the truck and trailer stopped perfectly, as if the trailer had no been there. So keep in mind, my rating of GOOD was to draw your attention to the installation issue I faced. The PEFORMANCE of the hitch was EXCELLENT.

-- Etrailer Expert Victoria B - 10/08/2019
My Equal-i-zer hitch continues to perform as I had wanted and described in my review. It has an unstated safety benefit. I tow long distances without a load on my trailer. I keep the Equal-i-zer hitch fully installed but adjusted so there is only mild tension transferred forward. That keeps the receiver ball housing on the tongue of the trailer constantly pressed against the hitch ball. If for any reason the ball coupling lock should fail or have not been set, the trailer would remain coupled to the truck.
