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.

Etrailer was the only firm that had this shank in stock that I needed in time to use my trailer for an event. They insured the order was processed and I got the product in 48 hours. It fit great and got me on the road. Courteous and quick service. 908835

Everything came in the package and the product came earlier than I expected. Installing it was fairly easy. However the only thing that proved difficult was Torquing the ball down on the hitch head which luckily [RV dealer] was good enough to do that for me. I am happy With the product and looking forward to using it. 765823

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

Review from a similar Repl WD Shank in Accessories and Parts


My husband wanted this 18" thingy so he could put down the back tailgate on the truck with the RV attached. He took the truck and the RV to our local RV place. For a couple of packs of soda and a big smile, they put this on for him. He could have done it with some effort. But, they had the tools and the time. He is now very happy. He says every time, everything he has bought from etrailer has been the exact product he has wanted. Never a problem. 738279

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

Review from a similar Repl WD Shank in Accessories and Parts


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

Review from a similar Repl WD Shank in Accessories and Parts


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.

Totally satisfied with price, shipping and quality. Solved my tailgate problem, while still maintaining the integrity of the Equalizer WDH system. The additional 6” allows me to drop the tailgate while still hooked to the trailer. Thanks for the prompt shipping 735122

  • 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.

    Yes, you can just replace the spring bars and head of your current system to change the weight rating. All you would need is the part # EQ90-01-1099 for a set of bars and # EQ90-02-1000 for the head that are rated lower at 1,000 lbs tongue weight.

  • Recommended Shank with More Drop for Equal-i-zer 6K Weight Distribution System
    In order to use the Equal-i-zer Weight Distribution System part # EQ37061ET you'll need to purchase the shank separately. For this, we have a few options depending on the rise/drop requirements. I recommend the Equal-i-zer Weight Dist Shank part # EQ90-02-4100 which has a 7" rise or 3" drop. I have attached a full list of options below, brand does not matter. The MaxxTow Adjustable-Height Ball Mount won't work as the dimensions are not correct and it's hollow.

  • 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. You will then want to park your trailer on level ground and measure from the ground to the bottom of the coupler. If the top of your receiver opening is taller (which is most likely the case) you will want to subtract the height of...

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.

  • How Much Does the 6,000 lb Equal-i-zer Weight Distribution System Weigh
    The 6,000 lb Equal-i-zer Weight Distribution (WD) System # EQ37060ET weighs about 10 lbs less than the 10,000 lb System # EQ37100ET. It has a shipping weight of 98 lbs so if you take away about 5 lbs for the shipping cartons that leaves you with about 94 lbs. If you are concerned about moving it around, the spring bars # EQ90-02-0699 weigh about 14 lbs each, the shank # EQ90-02-4100 weighs about 20 lbs, and the head unit # EQ90-02-1000 weighs about 21 lbs.

  • Choosing the Correct Rise for Weight Distribution Shank
    To choose the correct weight distributing shank, you will just need to determine the height of the top of your Expedition's hitch receiver as well as the height of the bottom of the trailer's coupler. 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....

  • How Much Does the Equal-i-zer Weight Distribution System # EQ37100ET Weigh
    The Equal-i-zer Weight Distribution System # EQ37100ET that you referenced has a shipping weight of 109 lbs so it is a little hefty like the majority of WD systems out there. If you take away a few pounds for the shipping materials you are left with about 105 lbs. The Spring Bar # EQ90-02-1099 weighs in at about 17 lbs so if you removed both that would be 34 lbs, making the leftover weight 69 lbs.

  • Will Curt Weight Distribution Shank Work in Place of Equal-i-zer Shank for 2 Inch Receiver

We do carry the Equal-i-zer shank you are looking for though if you would like to use that, the Equal-i-zer Weight Distribution Shank # EQ90-02-4100.

For the system head, you will use the Equal-i-zer Replacement Head # EQ90-02-1000.

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.

  • How To Measure Trailer Frame Rail To Confirm Fit Of Equal-i-zer Weight Distribution System
    The maximum frame height mentioned for the Equal-i-zer Weight Distribution w/ 4-Point Sway Control # EQ37061ET is the actual size of the trailer's frame rails and not the ground clearance. You will need to measure your trailer's frame as the Equal-i-zer will not be able to bolt to your trailer if it's frame rails are larger than 6" tall. I included a diagram showing the measurement mentioned. The Equal-i-zer Weight Dist Shank # EQ90-02-4300 will be great at ensuring that you have enough...
