Video Transcript for Equal-i-zer Hitch Ball - Trailer Hitch Ball - EQ91-00-6120 Review

Today we're going to be taking a look at the 2-5/16-inch hitch bolt for Equal-i-zer weight distribution systems. This has been designed for use with the Equal-i-zer weight distribution systems. It's made from a high-grade chromoly steel construction. It's going to feature a nice strong durable design. It's going to have a rust-resistant double chrome plating. It does come with your lock washer and the nut so both of those components are included.

It's going to have your wrench flats here on the side which is going to allow for an easier installation. It exceeds SAE J684 testing and certification. The ball diameter is printed right there on top. That's going to say 2-5/16 of an inch. It's going to have a weight capacity that's also printed on there that says 12,000 pounds. The shank length, that's going to measure about 2-1/4 inches long and the shank diameter is going to measure 1-1/4 inches.

When you're ready to install it, this goes through the ball hole on the head assembly. Washer goes underneath and then you would install the nut and then you need to get it fully tightened down. You would need to get it torqued to the specifications listed by the manufacturer. That's going to do it for today's look at the 2-5/16 inch hitch bolt for Equal-i-zer weight distribution systems.

Big shiny (for now) ball.

on. Good stock and rapid delivery

Just fine. It’s a hitch ball. Cannot find the right words to review it. It is shiny and round and my rig has not fallen off so it must be great
Scott - 06/16/2022


Great ball. What can I say?


I ordered from here because they had them in stock and this kit came with everything I needed including the ball! Unfortunately when my packages came the ball was not there and when I called to inform them they without question shipped me the ball that should have came the first time. I have not installed the hitch yet but it’s very heavy and seems like it will do as expected and the costumer service was great!


This Equalizer hitch ball is solid as a rock! No issues at all.


Its a ball
you are reading a review of
a trailer ball
It preforms like a 2-5/16" trailer ball should
Doesn't fit a 2" coupler, push as hard as you want, even get your overweight friend to do that bounce thing that big people seem to have a knack at doing on all vehicle bumpers, wont fit. This is a good thing, because its the wrong size for a 2" coupler anyway, and its probably a safety hazard.
If you need to find a 2" ball, please email the people here at etrailer, they will hook you up faster than a felon on the run.


I bought an e-2 hitch for a travel trailer that weights 5900 lbs. dry and to be pulled with my GMC 1/2 ton pickup. It arrived three days sooner then I expected Which was nice. It took sometime to figure out exactly how to set it up, but the more you work with it the easier it becomes. I ended up dropping the L-bars to the lowest setting and used only 3 spacer washer in the hitch. At the final measurements the truck was the same level as without the trailer attached which is perfect. I took it out camping this weekend for a trial run. The trailer pulled perfectly and we had no problems. I ran into another camper who had the same exact hitch and loves his. I would highly recommend this hitch to anyone plus the fact it comes with about a $200 savings over the big name brands. Karen helped me with my order plus answered some questions for me during the installation process, Thanks Karen..


nice web site, easy to get around and find what I was looking for. I ordered a 9" drop for my Equalizer hitch and a correct size ball. They shipped as promised by etrailer. However the train had a derailment on it's way here. I sent an inquiry as to the where about of my package and they responded the next day with the train problem. I received an email and a phone call follow up from etrailer. I wasn't expecting this great customer service from them but was VERY PLEASED with the service. Got delayed a couple days NO PROBLEM for me. Looking thru the cataloge now for my next purchase.
Thank You etrailer


Had a great experience with Ordered all the parts I needed for my equalizer weight distribution hitch (needed a ball and thin walled socket). Saved about 2o bucks on the socket. Ordered on a Saturday morning and had all my stuff on my door in NC by Weds. Great customer service. Will be back.


This product worked great for me. It took a 1-7/8" three quarter drive socket and 3' extension handle with ratchet to tighten it because of the location it's in. Pulls a 7000lbs. trailer with no issues.


Purchased with a new weight distribution hitch. Very pleased with it how its holding up.


very easy transaction. etrailer makes it easy to get my money, quickly send ordered products exactly as described and provide good communication on status of order. I will certainly send more money their way when I need trailer products.


Works wonderful! More stable than a sway bar. Very happy with this purchase.

Working like a charm. Been on three trip so far. Wind, rain, drought roads. Pretty stable hitch!

  • Current Weight Distribution System Rides Rough
    If you are having a rough ride but the suspension setup on the tow vehicle acceptable when not under, then yes I suspect you have a WDS that is not best matched your situation. Please review the help articles I have linked. I suggest you try the Fastway e2 Weight # FA92-00-0800. This is for 500-800 lb. tongue weight and one the better rated WDS from customers. You will need a 2" Hitch Ball for this, I suggest # EQ91-00-6080. This is a 2" ball with a 1-1/4" diameter shank that 2-1/4"...

  • Recommended Weight Distribution System For 2016 Ford F-150 Supercrew
    The best way to determine which weight distribution system to get is to know the total tongue weight. This would be the tongue weight of your ready-to-tow fully-loaded trailer added to the weight of any cargo placed behind the rear axle of your truck. If you are towing a trailer weighing 5,500-lbs the tongue weight should be somewhere between 550 and 825 lbs. Add 200 lbs of cargo and you are around 1025-lbs of tongue weight. I would recommend the Fastway e2 Weight Distribution System,...

  • Recommended Weight Distribution System for a 2020 Lance 2375 Travel Trailer
    The use of a weight distribution system is indeed recommended for your 2020 Lance 2375 Travel Trailer because its weight is more than half of that of your 2018 Ram 2500. I am not saying that it would be impossible for you to tow your trailer without one but the difference between towing with one and without one would be a night and day difference. Most people do not realize what affects rear end sag has on the vehicle's braking and stability. The added sway control protection is also a...

  • Can Older Model Eaz Lift Weight Distribution System be Upgraded with Higher Rated Bars
    Although we do not carry Eaz Lift products, I did speak with someone there and she informed that the new weight distribution bars will not fit with older model weight distribution hitches because on the newer design the head of the bars are a little bigger and the locking slot is a bit lower. If you want to upgrade your weight distribution system without spending too much, I recommend the Fastway e2 # FA92-00-1200. This system has a tongue weight capacity of 1200 lbs and you would just...

  • Clamp-On Style 1,200 lb Weight Distribution System
    The Replacement Frame Bracket Kit 32333 won't allow you to convert your chain-style Husky system to the clamp-on style Centerline system. So if you want a weight distribution hitch with integrated sway control which is a clamp-on style, it would require a new system. The best option for a 1,200 lb system is the Fastway e2 Weight Distribution with 2-Point Sway Control # FA92-00-1200. I really like the Fastway for its superior sway control, which is created by friction at two points on the...

  • Weight Distribution Hitch Recommendation for 8,600 lb Travel Trailer
    For a travel trailer with an 8,600 lb GVWR, your loaded total tongue weight will be somewhere in the 1,000 lb range, and that's the number we'll use to get the right weight distribution system. The ideal system would be one in which your total tongue weight falls somewhere in the middle of the weight distribution system's tongue weight capacity. The system I highly recommend for your travel trailer is the Fastway e2 Weight Distribution with 2-Point Sway Control # FA92-00-1200. The Fastway...

  • Recommended Anti-Sway Weight Distribution Hitch for Trailer With 1,100 lb Tongue Weight
    For your trailer with a 1,100 lb total tongue weight, the weight distribution hitch I highly recommend is the Fastway e2 Weight Distribution with 2-Point Sway Control # FA92-00-1200. The two points of sway control on the e2 are at the brackets, and the friction is what creates the outstanding sway control of this system. It is also really easy to set up compared to systems that use chains, and is easily the best value among weight distribution hitches, with a unique combination of relative...

  • Which Weight Distribution Hitch for Featherlite 2 Horse Trailer
    Which weight distribution hitch you'll need will depend on the specs of the trailer- the GVWR and the tongue weight of the trailer. From what I was able to find it looks like a typical 2 horse Featherlite trailer will weigh around 8000-lbs fully loaded. I recommend using a weight distribution hitch like the Fastway e2 Weight Distribution w/ 2-Point Sway Control - Trunnion - 12,000 lbs GTW, 1,200 lbs TW # FA92-00-1200, which has a tongue weight range of 800-lbs to 1200-lbs, so it will work...

    Yes, the hitch ball part # EQ91-00-6120 that you referenced will fit the Equal-i-zer weight distribution head part # EQ90-02-1000 that you also referenced. You'll need a thin walled socket like part # ALL643216 to install the ball though due to restricted clearances.

  • Weight Distribution/Sway Control Recommendation for 4000lb GVWR RPod 180 Travel Trailer
    Fastway offers the # FA92-00-0600 e2 weight distribution/sway control system that would be ideal for the roughly 4000 lb GVWR of your Forest River Rpod 180. This system is designed for trailers with fully loaded tongue weighs ranging from 250-600 lbs, which is right in line with what the fully loaded tongue weight of your small travel trailer would be. For a 2 inch hitch ball, use # EQ91-00-6080 or # EQ91-00-6120 for a 2-5/16 inch ball. To install the hitch ball, you'll need a 1-7/8 inch...

  • Best Weight Distribution System for 2012 F150 4x4 Supercrew Ecoboost
    In regards to your 2012 F-150 4x4, I recommend a weight distribution system. Weight distribution systems are recommended if the vehicle is pulling a trailer that weighs more than 50% of the tow vehicle. The systems improve braking and handling while increasing the towing capacity of some trailer hitches. I took in consideration your tongue weight and gross trailer weight to pick out an appropriate system for you. Also because of the cargo that your're carrying, I factored in sway control...

  • Comparing 12,000LB Fastway e2 & Equal-i-zer Weight Distribution Hitch For 2022 Palomino Puma 28BHSS
    The Fastway e2 Weight Distribution # FA92-00-1200 is going to be the little brother to the Equal-i-zer Weight Distribution System # EQ37120ET. The main differences between these 2 hithes is the Fastway is designed as an entry level hitch for the person who is unsure of how much they tow. It relies on the 2 points of sway resistance where the bars ride on the frame brackets and comes with a 10-year warranty. The Equal-i-zer is designed to be the last hitch you need to buy and includes a...

  • Best Fastway Weight Distribution System for a Total Tongue Weight of 900+ Lbs
    In order to choose the correct weight distribution system, you will need to find the total tongue weight (TTW) of your towing setup by adding the tongue weight (TW) of both your loaded ready to tow trailer and any cargo stored behind the rear axle of the tow vehicle. An easy way to find this would involve using a tongue weight scale like the etrailer Trailer Tongue Weight Scale part # e99044. When choosing a weight distribution system, you will want your TTW to fall in the middle of the...

    The most important thing you need o know when choosing a weight distribution hitch is the total tongue weight. This is the tongue weight of your fully-loaded-ready-to-tow trailer added to the weight of any cargo you place behind the rear axle. The tongue weight of a trailer is typically 10 to 15 percent of the trailer so for a dry weight of 6780-lbs it could range from 678-lbs to 1017-lbs.

    To determine the correct Fastway weight distribution system for your setup you need to find your total tongue weight. You need to determine your trailer's loaded, and ready to tow tongue weight and combine it with the amount of weight you have behind the rear axle of your 2013 Ram 1500. You want your total tongue weight to fall somewhere within the range of the system you choose. From my research your trailer has a GVWR of 7,635 pounds.

The Trunnion # FA92-00-1200 is rated for a tongue weight of 800-1,200lbs and with your Silver Lake having a dry tongue weight of 775lbs before they add the battery and propane you will need the heavier rated hitch, by the time you add your additional gear.

As you are already at 900lbs before loading any gear I would recommend the Fastway e2 Weight Distribution w/ 2-Point Sway Control # FA92-00-1200.

With your trailer having a dry tongue weight of 738lbs it will quickly increase when they fill the propane tanks with 40lbs of propane and add a 50lb Battery # BRW34FR to the front of the trailer.

  • How to Select the Correct Weight Distribution Hitch Depending on Trailer Weight
    That's an excellent question, and the short answer is that you should wait until you have a trailer before getting a weight distribution hitch, as knowing its GVWR and loaded tongue weight is important to get best overall system. The reason is, if you get a system that doesn't have the needed capacity, it won't be effective, and a system that is rated too highly will give you a stiff and possibly bouncy ride. So in order to choose the best weight distribution system you will first need...
