Video Transcript for Equal-i-zer Weight Distribution EQ90-02-4100 Review

Today, we're going to be taking a look at the Equalizer weight distribution shank. This is designed for use with Equalizer weight distribution systems. It will replace the shank that comes with Equalizer systems rated from 6,000 pounds to 14,000 pounds, and that's the gross towing weight, so that would also be 600 pounds to 1400 pounds tongue weight. This can be used in either the drop position or it can be flipped over, and used in the rise position, whatever one works best for your application. The unit's constructed of a nice solid, sturdy steel construction. You can see here that the shank's completely solid.

Really nice design. It's actually dipped for corrosion resistance. The product's made right here in the USA. It is designed for a 2 inch x 2 inch trailer hitch receiver. The pin holes on the unit will accept a standard 5/8 inch diameter pin that's designed to get it secured to the hitch. Hitch pins and clips or hitch locks, those are sold separately, so if you're in need of something like that, you can check out some options here at etrailer.com.

Again, when it comes to the maximum amount of tongue weight, this is rated anywhere from 600 pounds up to 1400 pounds, and with the gross towing weight, it's rated anywhere from 6,000 pounds up to 14,000 pounds. A few measurements to go over with you real quick. If we take a measurement of the overall length of the unit from very front to very back, that's going to give us a measurement of right at 12 inches. If we take a measurement from the center of this hitch pin hole to the center of the adjustment holes, that's going to give us a measurement of right on 8 inches. From the very front to the center of the hitch pin hole, it's going to measure 9 inches.

From the back of that bar to the center of the hitch pin hole, that's going to measure 7 inches. Now, when using this in the rise position, you're going to have a maximum rise of 7 inches. That's from the inside top edge of the receiver tube of your hitch to the top of the shank, to the top of the ball platform on the weight distribution head assembly. If you're using it in the drop position, it's going to give you a maximum drop of 3 inches doing those same measurements. It's going to feature six adjustment holes. The distance between each hole measuring on center, it's going to be the same for all of them, those are going to be separated on center by an inch and a quarter, and the last measurement I want to give you, is simply measuring from the center of the hitch pin hole to the brace right here, so the weld actually extends to this point here, so if we measure to the closest point of the weld, that's going to give us a measurement of about 3 1/2 inches.

To the actual brace, that's going to be about 4 1/4 of an inch. That's going to do it for today's look at the Equalizer weight distribution shank.

I placed an order for a shorter Equal-i-zer shank, a hitch lock, and some bar pins. Some of the pins were on back order so etrailer split the order shipment and I was able to install the new parts in time for our trip to the Olympic National Park. This is my fourth order with etrailer and each transaction has been great. They have great products and outstanding service. No time for a photo because we are departing for the park. Thank you Susan H. 543401


Comments

It has been about a year and approximately 4000 mile of towing with the Equal-i-zer hitch setup. The weight distribution and sway control have worked flawlessly and we have not noticed any problems with cross winds or passing 18 wheedlers. This is the third weight distribution hitch I have had and by fat the best.

Purchased this item because my rv dealer installed the wrong shank on my equalizer hitch. I haven't towed with it yet, but so did install the hitch to the shank. All good so far. Item arrived fast from etrailer and despite the item being fairly heavy it survived in the box. I'm using this shank on a 2012 f150 FX4 towing a 32 foot travel trailer. 430956

The first one they shipped was the wrong one. Called customer service on Wednesday had right one by Friday. Exchange/return was a minor inconvenience. I will give them great marks for their expedient handling as I needed it to set up hitch for weekend hunting excursion. Went from crossover to truck, thus the need for more drop. Went together with hitch head in about an hour and I was on my way. Thanks for the great service. 231281

Not sure what happened, but it collapsed during a vacation trip. Had to replace it with a solid shank which is much heavier, but did the job. Mobile technicial said he had never seen a hollow shank before. 634120


Comments

How heavy is the trailer you were pulling? This weight distributing shank is only rated for trailers with a 400 lb tongue weight/4000 lbs towing or less. If your trailer exceeded those specifications, the shank could indeed fail.

We went from a 1994 Chevrolet C1500 to a 2018 F150. The receiver hitch was 3” higher on the Ford. The shank we had would not give me enough drop and the F150 tailgate could not be opened without hitting the RV’s tongue jack. This shank solved both problems. Excellent! 583955

I purchased this to replace my 12” long hitch. This allowed me to keep my tailgate down and pull my camper. The hitch came in 2 days and took 10 min to swap the head from my Husky Weight Distribution Hitch. Still has the same 14,000lb rating as the 12” I took off. Of course my wife and kids were happy that we were able to take the golf cart for the first time with the camper. Great product! For reference, my truck is a 2015 Sierra 2500HD duramax pulling a 2018 Cruiser Embrace EL280 @ 6360lb dry. 628531

Toughest shanks on the planet that we have found for our customers come from etrailer and Equalizer (Progress Mfg). Don't let trying to save a few bucks put your rig at risk like the cast iron drawbar did in the photo below that was sent to me by a customer. If you buy the cheapest shanks, make sure you have good safety chains you will likely need them. Get the best from etrailer, Equalizer. 551524

I needed the extra length of this hitch shank to get my trailer hitch ball out from under the spare tire on my Jeep JK Wrangler Unlimited Rubicon. It works absolutely perfectly and is built extremely strong. I am using with an Equal-i-zer hitch system, but would be suitable for most other weight distributing hitch configurations if the centering between the adjustment holes is correct for your ball mount. 529658

Allows me to tow a travel trailer with my tailgate down (2011 Ram). I did not notice any difference in feel when towing compared to my previously shorter shank. There is no issue with the travel trailer hitting the tailgate- the length is perfect. This is much safer than using a hitch extender. The bolt pattern mated to my existing Husky brand hitch head. 386597

My order (107131659) arrived, but after test-fitting the extended shank onto my vehicle, I only have 6" of clearance on level ground. This will definitely not suffice, given the slope of my driveway. I'm hoping to get some help. What I'm ultimately trying to do is get my tow vehicle & camper trailer's Equal-i-zer hitch set up correct so that the trailer couple and the vehicle hitch ball are relatively level with one another before the hitch is connected (as per Equal-i-zer's instructions). Unfortunately, this requires that I either lower the hitch (which, as I found, results in too low of clearance at the shank), or raise the trailer. Do you have any suggestions? What about an "axle swap," where the under-slung springs are moved to the top of the trailer's axles? Thank you for your assistance and any recommendations you may have. 575939


Comments

Depending on the diameter of your axle tube, it might be possible to swap the leaf springs from the underside to the top of the axle. This will gain you about the diameter of the axle as a gain in height. For a 2-38 inch diameter axle, use part K71-384-00 or for a 3 inch diameter axle, use K71-385-00.

Not much to you can say about a shank. However, the service was great. I had ordered a different (to short) shank from Amazon and it took a week to arrive and wasn't packed or wrapped with anything. The paint was chipped and the edges banged up so much it wouldn't go into the receiver with out filling the edges. etrailer had it delivered in 2 days and the custom packing was so so good I didn't think the box UPS deliver was the shank. Great job etrailer! You'll be the first place I now look for accessories for my truck and trailer. 223907

Functionally the hitch is fine. The finish on it was very bad, it looks like they got the hitch from a scratch and dent sale and sprayed on some cheap paint. The hitch was supposed to be dipped but you could see the chipped paint underneath and smell the paint they put on it. I hope it will not rust out right away. 388918

I did not realize that I would need a longer shank when we switched tow vehicles, but the Nissan Armada receiver is actually higher than my GMC 2500HD. So much so that the 3" drop I was using didn't work. Fortunately eTrailer had this in stock and got it too me in 2 days (I had it expedited). It looks and works exactly like the Equalizer shank I had originally, but with a longer drop. 414359

I have a 2500 gmc sierra short bed and travel trailer. We purchased a golf cart and wanted to take the cart with us as when camping sites allow golf carts. Since my bed is 78" long I have to take the front cover of the cart off ( ezgo rxv) and I have to remove the tailgate because there is not enough room to lower it because of my trailer's electric Jack stand. My original equalizer weight distribution shaft is 12" so this gives me an extra 6" so I can leave my tailgate on and down. I no longer need to take the front cover off of the cart and the rear wheels are completely on the truck. Thanks George 451315

I'm now able to open the tailgate of my truck with the trailer attached. Side effects of using the longer shank are; power cable almost too short and original safety chains were too short and had to be replaced. But, the goal to be able to open the tailgate with the trailer attached was accomplished. 396883

  • How to Determine What Rise/Drop That is Needed for Weight Distribution System
  • To determine how much of a Rise or Drop you would need so that your towing setup is level you will need to compare some measurements. Start off my parking your 2017 GMC on level ground and then measuring from the ground to the top of the receiver opening.

  • Is Anything Else Needed to Install the Equal-i-zer Weight Distribution System # EQ37041ET
  • The only thing you will need to add to the Equal-i-zer Weight Distribution System # EQ37041ET you referenced is an adjustable shank. For this, I recommend the Equal-i-zer Weight Distribution Shank # EQ90-02-4100, which will give you up to a 7 inch rise or a 3 inch drop. For this same system that includes the shank, you can use # EQ37040ET. I have attached a short video demonstration on this system that you can also check out.

  • Equal-I-zer Weight Distribution Shank that has More than 3 Inches of Drop
  • There are other shanks you can use that offer more drop so you can tow the trailer level. For example shank # EQ90-02-4400 offers up to 9 inches of drop. To determine the amount of drop you will need there are a couple of measurements to take. First, level the trailer and measure from the ground to the bottom of the coupler. On the truck measure from the ground to the top of the receiver opening. The difference will be the amount of drop you will need.

The difference between these two measurements will be the rise (or drop) that is needed. You did mention the height of your trailer hitch receiver at 20 inches in your question. For the most accurate measurement, I recommend also measuring the height of your trailer tongue when it is level....

  • Weight of Equal-i-zer Weight Distribution System
  • The head unit of the Equal-i-zer Weight Distribution System # EQ37101ET weighs a little over 20 lbs while the pair of spring bars weigh about 35 lb (total, not each). This system does not come with a shank so depending on the rise or drop you need you can use Equal-i-zer Weight Distribution Shank - 12" Long - 8" Rise, 4" Drop # EQ90-02-4200 or Equal-i-zer Weight Dist Shank - 12" Long - 7" Rise, 3" Drop # EQ90-02-4100.
