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.

Steel-on-steel friction works to prevent and correct trailer sway in this unique weight distribution system. Sway control brackets ensure that your trailer stays in line with your tow vehicle. 2-5/16" Hitch ball and 2-1/2" shank included.


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!


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.


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.


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


I’ve been pleased and would highly recommend etrailer.


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.


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


Delivered earlier than expected. Your price was very good.


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.


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.


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


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.

  • Weight Distribution and Sway Control for Travel Trailer with 1,600 lb Tongue Weight
    The best option for weight distribution with sway control for a trailer that has a 1,600 lb tongue weight would be the Equal-i-zer part # EQ64FR which has what many consider to be the best sway control and weight distribution.

  • Which is Better Weight Distribution Shank Position Slightly Nose High or Slightly Nose Low
    If you have to pick between slightly nose high or slightly nose low I'd recommend the lower option as nose high setups typically are more likely to sway since it lowers tongue weight. Now that said sometimes with a slightly higher setup using unloaded measurements you end up closer to level when the weight of trailer is on the vehicle suspension due to suspension compression so you might try both just to be sure.

  • Recommended Weight Distribution System for a Jayco Eagle HT 284bhok
    What you really want to do when choosing a weight distribution system is try to get as choose to the middle of the systems capacity as possible. The typical tongue weight of a trailer will be anywhere from 10% to 15% of the total weight of the trailer. With that being said, I do suggest going with the Equal-i-zer # EQ64FR. This will have the minimum tongue weight of 1,200 pounds and the maximum tongue weight of 1,600 pounds. I should not that with the minimum tongue weight being 1,200...

  • Can Equal-i-zer 12K Weight Distribution System Be Upgraded to 16K
    The highest rated Equal-i-zer Weight Distribution System is part # EQ64FR which is rated for 1,600 lbs of tongue weight. Unfortunately, you can't upgrade from another system to this capacity as the capacity comes from the head and not just the spring bars. Therefore, for your new trailer you will need to purchase an entire new system but you should still be able to sell your old one to offset some of the costs. I can't recommend using an underrated system as that would be unsafe and void...

  • Weight Distribution Recommendation for Reflection 315RLTS Travel Trailer
    A weigh distribution system is going to be a really good idea based on the weight and size of the camper you plan to tow. You have a heavier duty truck so typically sway won't be too bad but the WD system will do an excellent job preventing sway from heavy winds or passing semis but what it also helps with is braking and handling since it puts more weight up on the front axle of the tow vehicle. Based on the dry tongue weight you mentioned the Equal-i-zer kit part # EQ64FR would be a...

  • Alternative to Anderson Weight Distribution System 3394
    I do have an option for you but we don't carry the Anderson Weight Distribution System 3394. That said, we do have a better option in the Equal-i-zer Weight Distribution System part # EQ64FR which is considered to be the best option on the market by most. It has weight distribution properties and four point sway control for maximum stability. It's not the lightest or most quietest system out there but it preforms better and is backed by a lifetime warranty. Like the Anderson, it has a 16K...

  • Recommended Weight Distribution Hitch with Sway Control for Trailer with 1,300 lb Hitch Weight
    The Equal-i-zer Weight Distribution System part # EQ64FR is what I recommend for any trailer between the 1,200 lb - 1,600 lb tongue weight range. It has a 2-1/2" shank so you don't need to worry about extra slop with an adapter and it has some of the best sway control properties on the market being a true four point system. It's also backed by a lifetime warranty and made here in the USA. Please note, this system is a bit more expensive than some of the others out there but you'd be hard...

  • Weight Rating of Hitch Ball for 16K Equal-i-zer Weight Distribution System w/ 4-Point Sway Control
    The hitch ball for the 16K Equal-i-zer Weight Distribution System w/ 4-Point Sway Control # EQ64FR can actually be found as part # EQ54FR and is rated for 16,000 lbs just like the weight distribution system. This same hitch ball is likely used for some of the lower-rated systems from Equal-i-zer as well. Basically if the system comes with a 2-5/16" hitch ball and isn't rated for more than 16K it likely has this hitch ball. Attached are some review videos for you to check out.

  • Recommended Weight Distribution Hitch For A Forest River XLR Boost
    Tongue weight is typically 10-15 percent of your trailer weight. So with your trailer weighing 13465 pounds the tongue weight could be anywhere between 1346 pounds to 2019.75 pounds. To determine your trailer's tongue weight I would recommend finding a commercial truck scale, weigh the vehicle only with the trailer attached, and then subtract from this the weight of the vehicle only without the trailer attached. If you have to much weight exerted on the hitch ball, the force could overload...

  • Which is Better Weight Distribution System Reese Strait Line or Equal-i-zer
    The Equal-i-zer weight distribution systems and the Reese Strait Line systems are widely considered to be the best two systems you can get. The sway control of the Strait Line setup is better than the Equal-i-zer, but the Equal-i-zer weight distribution has yet to be improved upon so it has the edge. So if you are wanting the best WD the Equal-i-zer is the way to go but if you want the best sway control the Strait Line is the way to go. Since you haven't had issues with sway I'd go with...

  • Recommended Weight Distribution Hitch for 2020 KZ Sportsman LE 333 KBKLE & 2019 Chevy Silverado 3500
    Choosing a weight distribution hitch should be done using the tongue weight of your trailrer; it looks like the 2020 KZ Sportsman LE 333 KBKLE has a dry tongue weight of 1280-lbs, which would likely be around 1400-lbs when loaded. You will want that weight to fall towards the middle of the range of the weight distribution hitch you use. It also looks like the 2019 Chevy Silverado 3500HD comes with a factory 2-1/2" hitch, so you'll want a weight distribution system that fits directly into...
