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.

I have been using this EQ hitch towing my Bullet crossfire travel trailer with my F-150 for over a year now and it handles great. Tows smooth and without jerking or a rough ride. It took a few times to properly balance it and adjust it properly but what a major improvement from towing without it. I recommend this EQ hitch very much!!

Excellent! I have towed over 5000 miles in 2 years with this hitch now and it is still like new. What a great purchase.
MarkG - 01/24/2020

Was needing a weight distribution system for towing my 16' toy hauler and with Kats help from etrailer I couldn't be happier with this product. Trailer has a dry hitch weight of 950lb and 1100lb loaded. Set up took me an hour or so, but now I feel comfortable hooking and unhooking. Took it on a 100 mile trip a few weeks back in heavy rain with strong wind gust and handled great! Without it I didn't feel safe going 60mph on calm sunny day.

I purchased this hitch for a 9000lbs travel trailer with a 1001lbs tongue weight. If your debating between a less expensive round bar and this setup, spend the money. This hitch is by far a better, easier, and safer setup. I purchased this hitch to replace a Pro-series round bar with a friction sway control bar. The Equal-i-zer's 4 point sway control is big step up from a single point sway control system. The 1st drive felt secure and safe. Install was easy, but time consuming for a 1st time installer. But worth it in the end. Here's some pointers. 1. get the right tools, rent or barrow a the torque wrench to do the hitch ball 430ft/lbs, and shank bolts 320ft/lbs. The piece of mind that it's correct is worth it. 2. Plan for the afternoon, not a couple of hours. 1st setup is going to be close but your going to have to adjust it so plan on taking something apart. but setup is relatively easy, esp with the right tools. I had the trailer level the 1st go around to 2.5". So I had to move the head up one hole in the shank and then it was within 1". Distribution setup was still with in a proper setup, so I didn't have to make any further adjustments. As far as the coupling and uncoupling the hitch. Using the tongue jack to release the tension is easy to do and quick. Esp. with an electric jack. I never liked the round bar with chain setup on my previous hitch. High quality, easy install and setup, and seems to have great sway control.

Ordered the Equal-I-zer weight dist hitch as a reaplacement for original W/D anti-sway hitch trailer dealer sold me (was getting quite a bit of sway). Relatively easy to install, instructions were very easy to follow, getting a torque wrench (430 ft-lbs) for the ball had been my only concern. Weight distribution was right the first time, truck and trailer sit nice and level. The trailer tracked very well and there was no sway when being passed by large tractor-trailers. Less noise than I expected after reading reviews when researching hitches. Very happy with the hitch and the GREAT service from etrailer. Highly recommend.

I'm completely new to towing and the RV world. I searched high and low for a hitch that would make towing my 29 ft RV the least stressful as possible. I found this one but was still a little nervous about the whole experience. Once it arrived in so many pieces I did get overwhelmed, but the videos and booklet provided truly helped a complete amateur put it together without issue. And then once I drove with it, WOW! I honestly forgot I was towing a 29ft RV at times. I had no issues turning and no issues handling. The weight distribution really did work. I even drove it in torrential downpour and had no issues with sway at all. I am so impressed with this product and am so happy I found it. A true life saver for a beginner!!

- EQ37120ET

This hitch setup is worth every penny. Install was not painful and instructions were clear. After setup was finished I took her for a spin and I was amazed at the difference. The ride was smooth and no sway!!!! No more friction sway control for me!! I would recommend this to anyone who is in the market for a WD hitch.

- EQ37120ET

I installed this hitch on my 2007 Toyota Tundra. I use to have the chain style. Big difference when getting next to rigs. This hitch is a much tighter tow. Glad I upgraded.

- EQ37120ET

The Staff at etrailer made the purchase simple and very helpful in picking the right tow package product. Installation instructions were sent when the product arrived. Great product n company! Thank you so much Connie!

- EQ37120ET

This hitch has been great! No complaints and no regrets at all. It does a great job of anti-sway, which was my main reason for purchasing the Equalizer over other weight-distribution hitches. I did a bunch of research before purchasing this, and the majority of the reviews were very positive. This is also my sentiment in my experience of using it over the past year. You just need to make sure it is installed correctly and setup properly, otherwise your experience could be different. It's not difficult, just read the instructions and double check what you're doing. Once it's setup properly, you'll never have to touch it again.

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-concerting

You realize that the friction where the spring bar slides in the L bracket is responsible for the sway control right? Reducing the friction would reduce the sway control of the unit... I am interested to try this product. I think what you are saying about getting the right set up for your individual rig is the most important thing.
-- comment by: Donny - 02/01/2014

The nylon jackets may very well reduce the sway control ability of the unit. For some applications, the reduction is sway control is not problematic and sometimes the noise is just too much. It is up to the user as to what they need more, but the jackets are available for those that want to get rid of some of the noise.

We made a trip to the Pacific Northwest from Arkansas and I have to say, the hitch performed perfectly. Even in a high wind, which is common in Wyoming and the plain states there was no problem keeping a straight line going down the road. One time, when I wasn't paying attention and ran off onto the shoulder of the road, the trailer didn't sway at all but kept straight and allowed me to return to the road without incident. I would recommend this hitch to anyone pulling a trailer of any significant weight behind them. I have a 33 foot RV and pulling it with a 2015 Chevy Silverado 1500.

Its been over a year since I purchased my Equalizer hitch system and I am completely satisfied with it. Occasionally I have to spray some lubricant on the pivot points on the receiver end to keep the noise down but other than that It works as advertised and I would again rate it 5 stars.

The Equalizer Weight Distribution System w/4 point sway control is as good as advertised. The installation took me approx 2.5 hrs and it was not difficult, just took a little time to make fine tuning adjustments to get the performance from the system that I wanted. The Equalizer System has removed an estimated 95% of the sway issue that I was having while pulling a 29 ft travel trailer with a mid-size Chevrolet Colorado pickup. Looking forward to getting out on the road and giving it a thorough testing, but so far it meets my expectations.

This hitch was a great investment!! It has made a huge difference in how my trailer handles in the Texas winds. I used to get white knuckled every time that I set out on a trip with my previous chain hitch and seldom ever felt comfortable in pulling the trailer at speeds in excess of 45 mile per hour. Now I can move along at normal Dallas freeway speeds in comfort. This hitch was a welcomed addition to my RV experience.

Great product except for one thing. If you are going to sell this hitch either sell it with ball already attached or include the 1 7/8 thin wall socket with it. Could not find socket anywhere locally and finally had to dismantle Equilizer bar sockets which is no easy task , and then use regular socket that I already had, what a pain. Other than that great service and ultra fast shipping. I think I ordered it Tuesday night and had it Friday night. Great job. Will repost once all is installed and try it out.

Best hitch on the market for anti sway and load equizling. Quick hook up, love it!

Hitch works perfect. I first used it to pull my 24 ft car hauler with my Yukon XL and it worked flawlessly. I upgraded trucks to a 2500 Duramax and reset the hitch for it and all is perfect still. Great quiet hitch!

- EQ37120ET

12000 lbs. hitch was a great improvement over my previous bent bar hitch with chains. Trailer sway has decreased a lot. MY 35 foot trailer pulls straight except when it is windy. I am no longer bothered by passing vehicles. Was noisy until I added the nylon pads from equalizer. Much quite now.

Keep in mind that the jackets or pads will decrease the effectiveness of the sway control to a degree because they limit some of the metal-on-metal friction which provides the sway control.
-- Etrailer Expert Mike L - 03/06/2019

- EQ37120ET

Biggest Pros: - Easy to install initially (though I did have to buy a special socket, 1 7/8, to hook up the ball, so this could be a con too. A wrench won't work) - It really does do a great job of stabilizing the trailer going do the road) Biggest Cons: - Weights around 100 lbs and has actually threw my back out trying to hook it up. - Hard to connect stabilizing bars, as well That said would not buy again or recommend, am currently looking for a better solution. The Doctor bills alone could cover a much more expensive unit. Not to mention the pain!!! Together these reasons are enough for me to NOT recommend! NOTE: I am a 38 year old man that exercises and lifts weights at least 5 days a week, usually 7; my life revolves around the gym. I say this only so you believe me - This thing is heavy and awkward.

Works great. We live in the mountain area of East Tennessee. I hit mountains no matter which way we travel. Been to Western New York to Central Florida. No problems.

- EQ37120ET

I received this hitch about a month ago and couldn't install right at first due to some issues I was having but I have finally got it installed and set up right. This is great! I will go on my maiden voyage Memorial weekend but I'm sure it is going to perform as expected. Excellent price that no one can touch. Instructions are easy to follow and detailed the way it should be. Time, was about as expected, so don't rush because you don't want to miss any steps.

Well I have owned this hitch for a year and it has worked flawlessly. In July we took our camper on a 2000 mile trip and we had no issues with the hitch at all. We were in all types of traffic through large and small cities, we didnt have any sway issues because the hitch, now broken in, works much better than I knew it would. I had installed the pads under the slide bars and use the grease to quieten it down when in all the turns I made during this trip. I dont believe there is a better hitch out there that can tame my 38 ft 9000lb Jayco than this Equalizer. Best money spent here. 11/7/17

The equalizer hitch has made towing my horse trailer much more secure. I hardly feel the trailer and it does not sway at all. My truck is now even, I didn't realize how the trailer impacted steering and with the new equalizer hitch, steering is better. I am a 60+ year old woman and I can set up the hitch and unhitch on my own. The instructional video is very helpful.

- EQ37120ET

Fantastic Hitch! etrailer had the best price by far, arrived within 4 days of placing the order in excellent condition with no shipping damage or missing parts. Mt RV Dealer did the original setup, but their installers apparently never watched a video on proper installation, as they took no before or after measurements of my truck wheel well height, never used a torque wrench, and placed the sway bracket assemblies at 27 inches from the ball when 32 inches (factory recommended distance) was easily available on the trailer. Many other install errors as well like incorrect number of spacer washers and incorrect L bracket mounting hole positions, all of which caused my 2016 Ford F-150 to squat while towing. Never assume the dealer service department knows what they are doing! Once home, I set the hitch up as instructed by Equal-i-zer without too much difficulty. This hitch now has my truck sitting level and tows like a dream with very little sway at all, and I tow a 35 foot travel trailer. Keep the hitch lubed as instructed, and use the optional sway bracket jackets and this hitch is fairly quiet. Well worth the money, no more white knuckles!!

- EQ37120ET

All good with this hitch! We have pulled in high cross wind without much noticeable sway. Our truck and the trailer are level. After I learned the trick of raising the tongue a little above horizontal, I can install and remove the arms without using the cheater bar. I had to adjust the hitch after I traded trucks but it was a simple thing and took very little time. We've had people stop to look at it because they were tired of using the hitches with chain adjustment. Couldn't be happier. The support from etrailer staff is great.

I recently replaced my weight distribution and sway bar that had the chains for distribution and the brake style anti-sway with the Equalizer 1200. I also had purchased a scale to weigh tongue wt. I wanted to wait until I had some good miles on it before I reviewed. I tow a 33 1/2 ft toy hauler with a RAM 1500 eco-diesel and am pretty much maxed out on what I can safely pull. After weighing my rig at a truck stop and then checking my tongue wt, I called etrailer and got excellent confirmation on which set up to use. The 1200 worked like a dream. My wife actually let go of the dash board and commented on how much smoother and controlled the ride is. If you have any doubts as to the ability of these set ups, put them to rest. I couldn't be more pleased. The sway is all but eliminated and the ride has improved dramatically. On another note, I also found the 1200 cheaper but without the ball. I submitted the link as directed to and I was expecting them to reply with, 'this isn't the same'. Instead, they added $22 to the price I submitted to include the ball and then gave me their guaranteed price match. To me, this speaks volumes for their honesty and integrity. This is not my first purchase through them and I will not hesitate to use them again.

- EQ37120ET

Hitch does very good job of weight distribution and sway control. Other than getting grease on you it is easy to use and hook up. My wife has it mastered and she generally avoids mechanical stuff. Only reason for 4 vs 5 star is the messiness of the grease. You need to keep ball, hitch plate and arm supports lightly greased. Make sure to not bump into it or you will be cleaning.

- EQ37120ET

I cannot rave enough about this set up. I tow about a 10K trailer (RV when fully loaded) with a Ford F150 (yes an F150... but it was built for towing heavy and in fact, is actually rated better than my F250 Super Duty to tow heavy). But it is working hard, no doubt and with this hitch I really cannot tell the trailer is there. In my humble opinion, best on the market, even tows better than my goose neck did. I have put the same set up on my 4 horse trailer and will do so for my car hauler soon.

- EQ37120ET

Product was easy to install, following instructions that came with. Video's online also helpful. It was recommended to use thin wall 1 7/8" socket to tighten the hitch ball nut, but was able to get a impact socket into the space. The trick is to turn the square weight distribution receiver's out to the side. ( ie...perpendicular to the hitch receiver. ) They come from factory at a 45 degree angle, turn them out to 90 degree's. Then the socket fits in to tighten the nut. Great videos online from product on how to make sure your weight distribution is correct once installed on tow vehicle and trailer.

    To determine if the drop of Equalizer's standard shank is sufficient for your tow vehicle and trailer combination, you need to measure from the ground to bottom of the coupler. Then do the same from the ground to the top of the receiver on your Ram 2500. If your hitch height is greater than your coupler by more than 3 inches, a larger shank is needed.

  • Best Weight Distribution System for a 10,000 lb Travel Trailer
    For starters, if the gross combined weight rating (GCWR) is 16,200 lbs and the gross vehicle weight rating (GVWR) is 7,000 lbs then your towing capacity is 9,200 lbs, not 10,800 lbs. The correct GCWR and GVWR figures will be found on the driver's door jamb. However, the towing capacity of the vehicle only needs to be rated for the gross trailer weight (GTW). Regardless, if the trailer has a hitch weight of 1,000 lbs I recommend using the Equal-i-zer Weight Distribution System part #...

  • How to Choose Correct Equal-i-zer Weight Distribution System
    The ideal situation for selection of a weight distribution/sway control system is that your fully-loaded trailer's measured tongue weight (TW) falls right near the middle of its operating range. The weight of any cargo behind the rear axle of the tow vehicle, which will act just like trailer TW, should also be figured into the TW calculation. For a total effective TW of 1000-lbs you will want a system such as the Equal-i-zer 4-Point # EQ37120ET that works over a TW range of 800 to 1200-lbs. If...

  • Comparing Reese Steadi-Flex Weight Distribution with Equal-I-zer Weight Distribution
    The Reese Steadi-Flex weight distribution systems, including # RP66560, are relatively new so that accounts for the lack of customer reviews on them. I have experienced this system first hand though and it works quite well and is very easy to use; especially for someone like you who has experience using weight distribution systems. It and the Equal-I-zer systems work in much the same way. The Equal-I-zer systems have more metal on metal contact that does require a lot of adjustment and...

  • Can a Weight Distribution System Be Used on a Motorhome with Airbags
    Yes, you can use a weight distribution system on your motorhome while towing a trailer. Since you have airbags, you will want to couple the trailer and then let the airbags adjust. Once the airbags adjust, you can then set the spring bars on the weight distribution system to take the remaining sag out of the equation. In order to select the correct weight distribution system you will need to determine your total tongue weight (TTW) which is the loaded ready to tow tongue weight of the...

  • Upgraded Shank To Use Equal-i-zer Weight Distribution System On a 2017 Chevy Silverado 2500
    I have exactly what you need for your Equal-i-zer Weight Distribution System part # EQ37120ET, the Equal-i-zer Weight Distribution Shank part # EQ90-02-4700. This shank has the same rise/drop as the one that came with the above system but has the larger 2-1/2" shank that will fit securely inside the receiver tube opening on your 2017 Chevy Silverado 2500. The receiver tube opening on your 2017 Chevy Silverado 2500 is 2-1/2", not 2-3/4". This will reduce rattle and play tenfold when compared...

  • Recommended Weight Distribution Hitch with Sway Control for 2006 Eclipse Attitude Toy Hauler
    When choosing a weight distribution hitch, you want to choose based off of the loaded tongue weight of your trailer; I wasn't able to find any definitive specs on this specific model but most of the trailers I found in the Attitude line had tongue weights of around 1000-lbs. You will want that tongue weight to fall towards the middle of the range of the weight distribution system that you choose. With all of that considered I recommend using something like the Equal-i-zer Weight Distribution...

  • Is a WD System Needed to Tow a Trailer with a 2012 Ford F-250 Diesel
    A WD system is recommended when the trailer weighs more than half of the weight of the tow vehicle. If this is the case for your trailer and your 2012 Ford F-250 then I do recommend using a WD system as it will distribute the Tongue Weight (TW) of your trailer among all of the axles. This will give you a level towing setup that results in better ride quality and control. Should you need a WD system you will want to choose one that has a Tongue Weight (TW) range that the Total Tongue...

  • Weight Distribution System for a 2012 Ford F-150 and 7,800 Pound Travel Trailer
    The 10,000 pound capacity system, # EQ37120ET, would be the better choice. The reason is how weight distribution systems should be chosen. You would not go by gross trailer weight capacity (unless it was not rated high enough) but instead go by the total tongue weight. Total tongue weight is calculated by taking the tongue weight of the trailer when loaded and ready to tow and adding to that the weight of anything loaded behind the rear axle of the tow vehicle. If your trailer is loaded...

  • Comparing Equal-i-zer and Curt TruTrack Weight Distribution Systems
    Between the two kits you mentioned the Equal-i-zer part # EQ37120ET is the best choice. This is the highest quality option out there for a weight distribution system and is what Curt tried to emulate with their TruTrack part # C17501. The Curt kit is relatively newer and while not a bad system by any means does not have the decades long tried and true reliability that the Equal-i-zer kits have. It will perform the best and last the longest. Plus it comes with the 2-5/16 inch ball you want...

    I'd be happy to help you find the best weight distribution system for your 2016 Toyota Tacoma to haul your 2015 Skyline Dart 214BH travel trailer. In order to choose the best weight distribution system you will need to know your total tongue weight (TTW), which is the tongue weight of your fully loaded and ready to go Skyline plus the weight of any cargo behind the rear axle of your '16 Tacoma. The tongue weight is typically between 10% and 15% of your trailer's GVWR but you'll want to...

  • Best Weight Distribution Hitch for 7500 Pound Jayco 27BH Travel Trailer
    Your Jayco 27BH has a dry weight of 6015 pounds, 1485 pounds of cargo capacity, for a maximum total weight of 7500 pounds. Tongue weight should be between 750 to 1125 pounds. I think the best weight distribution hitch for your rig is the Equal-I-Zer # EQ37120ET hitch rated for up to 1200 pounds of tongue weight and 12,000 pounds towing. It does not use chains and the 4-point sway control is very good. Additionally, set up and take down is fast and you have no limits on backing up. I...

  • Weight Distribution for Dump Trailer with 8 Inch Tall I-Beam Frame
    I do have a great option for you but a Reese system is not going to be the best choice in this case. You will need to box the trailer frame where the weight distribution brackets will go by having steel plates welded on. What you can use is an Equal-I-zer system, # EQ37120ET as an example, and then add 2 outer link plates, # EQ90-02-5378, sold in quantities of 1, and 2 inner link plates, # EQ90-02-5208, also sold in quantities of 1. That would allow you to use the system on an 8 inch...

  • Recommended Weight Distribution System For A 9000 lb Trailer
    In order to determine the best weight distribution system for your towing setup, you will need to calculate the total tongue weight of your loaded ready to tow trailer and any cargo stored behind the rear axle of the tow vehicle. To do this, I suggest you consider the Sherline Trailer Tongue Weight part # 5780.

    When trying to decide on a proper weight distribution (WD) system for your towing rig, you will need to know the total tongue weight (TTW) of your set-up. The total tongue weight will be a fully loaded ready to tow trailer, plus any weight located behind the rear axle of your tow vehicle. You want to use a system where your total tongue weight will fall in between the WD system's tongue weight range. I have attached an article that will explain how to find the TTW of your towing rig.

  • Recommended Weight Distribution System with Sway Control for 6,500 Pound Loaded Trailer
    When choosing the right weight distribution system, the most important factor to consider is the total tongue weight of your setup. The total tongue weight is the loaded tongue weight of your trailer along with any added weight behind the rear axle of your tow vehicle. Typically the tongue weight will be around 10-15% of the trailer's total weight. So we can estimate the loaded tongue weight of your trailer to be around 650-975 pounds. If we add an estimated 200 pounds that will be coming...

  • Does Weight Distribution Hitch Stop Persistent Trailer Sway
    Weight distribution systems can help greatly with sway from passing semi trucks and high winds, but if you are getting a persistent sway all the time on the highway the issue is actually the loading of your trailer. You need to move the weight of your cargo further forward in the trailer so that you can get it to be around 10-15 percent of the total trailer weight. That's the only way really to prevent persistent sway. Also make sure your trailer is sitting as level as possible. The...

  • How to Gain Clearance for Turns Using Equal-i-zer Weight Distribution System
    I verified with Equal-I-zer that adding some washers to raise the hitch ball of your weight distribution system # EQ37120ET is perfectly fine. A few things to keep in mind: If you use a different hitch ball make sure the threads do not hang below the cavity of the hitch head. Also, make sure the top of the hitch ball isn't more than 1 inch higher than the coupler, and finally make sure you torque the ball down to spec.

  • Correct Equal-i-zer Weight Distribution System for 2020 Rockwood Ultra Lite 2608BS
    With a predicted loaded trailer weight of around 7,600 pounds (which would give you a loaded tongue weight like you mentioned of around 912 pounds) I highly recommend the higher-rated Equal-i-zer Weight Distribution System # EQ37120ET. This system has a tongue weight capacity range of 800 to 1,200 pounds, so even if you were to end up on the lower range of your estimate, it's still going to fall comfortably within the range of this system for ideal operation. With the above information...

    If you want to go with one system the best option will be the 1,200 lb tongue weight kit # EQ37120ET. It would be better to have more tongue weight capacity than needed than not enough when needed. The ride might be a little more stiff when loaded lighter but you can compensate for that by lowering the spring bar tension.

    The best weight distribution system we offer is the Equal-i-zer Weight Distribution System part # EQ37120ET which is rated for up to 1,200 lbs of tongue weight. The reason that the Equal-i-zer is the best is because it has the best sway control on the market and it is the only system with a forged head which means it is very durable. It also comes with everything that you need and it will not require any drilling into the frame. The shank can be flipped to give you the 3" rise you need....

    We sell more Reese dual-cam (Strait-Line) weight distribution systems than Equal-I-zer systems. But we have also carried Reese products since etrailer began and haven't had Equal-I-zer as long. The thing about Equal-I-zer is that they have brand recognition. People know who and what Equal-I-zer is which is why they are so popular. Their systems do work but like any friction type of sway control system they make a lot of noise and components can wear out faster than non-friction systems....
