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.

  • Weight Distribution and Sway Control Recommendation 2018 Jayco Eagle 322RLOK
    The best weight distribution/sway control systems are the Equal-i-zers like the part # EQ64FR you mentioned but the trick is picking out a kit that the trailer's loaded tongue weight falls right into the middle of. This system has a tongue weight range of 1,200 - 1,600 lbs. I looked up your 2018 Jayco Eagle 322RLOK and based on the dry weight, dry tongue weight, and GVWR this would be a great option rated perfectly. For a hitch ball you'd then want the part # C40008 and the socket part...

  • 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...

    Hitch rattle/noise is pretty annoying. We have products like the Hitch Immobilizer part # BX88225 which you can use to eliminate all of that noise. This uses a couple U-bolts to pull the shank of the ball mount tight against the hitch tube to get rid of the movement. This specific model fits 2-1/2 inch hitch sizes like you have as well.

  • 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...

  • What Weight Range Weight Distribution for Trailer with 1,400 lbs Tongue Weight
    If you have a tongue weight of 1,400 lbs a weight distribution with a higher tongue weight range would be ideal. Especially when you consider that the weight of any cargo behind the rear axle of the tow vehicle gets added as additional tongue weight. So a higher rated system like the Equal-i-zer part # EQ64FR would be your best option as it has a tongue weight range of 1,200-1,600 lbs. You'll also need a thin-walled socket to install the ball # C40008 too with the # ALL643216.

  • Recommended Weight Distribution System for 13,500 Toy Hauler
    If your tongue weight is between 1500 and 2000 lbs (which it should be, given the 13.5K weight of your toy hauler), the Blue Ox # BXW2000 would be perfect for you. The system includes a shank that would provide up to 2 inches of drop, and combines weight distribution with sway control which is really needed for a long towable like your toy hauler.

In that case, I can highly recommend the Equal-i-zer # EQ37121ET which is specifically designed for trailers with a tongue weight between 800 and 1200 lbs (make sure you include cargo stowed in the truck bed behind the rear axle as tongue weight). The system includes the 2-5/16 inch...

For a 2 inch shank with a a 16,000 lb towing/1,600 lb tongue weight capacity, what you will need is the Reese Weight Distribution Shank # RP54998.

    Adding air bags won't remove tongue weight or stress from the weight distribution system, and since there are no bars rated for nearly 1,500 lbs of tongue weight from Fastway, it does mean you need to upgrade to a more robust weight distribution system.

  • 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.

  • Weight Distribution System for a Toy Hauler with a Tongue Weight of 1600 LBs
    For your 2021 Outdoors RV Trail Series 29TRX, there is something to keep in mind. With a tongue weight of 1600 pounds, we only have one Equal-i-zer Weight Distribution System that can handle that amount of weight. It's part # EQ64FR. The problem with this system is that 1600 pounds is the highest that it can handle. If your tongue weight goes up for whatever reason (how the toy hauler is loaded can affect this), the Equal-i-zer will become ineffective. Also, this system fits a 2-1/2"...
