Help on re-adjusting Equal-i-zer WD hitch

Hi, I recently purchase a used Sportsmen 16 feet trailer and the former owner let me his Equal-i-zer brand weight distribution hitch. It's the 600 TW / 6K GVWR model. The former owner use it to tow the TT on a 2008 Dodge Grand Caravan and I use it myself on a 2014 Dodge Grand Caravan so the adjustment are supposed to be identical. But the former owner told me than maybe the WD hitch may requiert a re-adjustment because the rear of his 2008 Caravan still sag more than front. But he didn't take care of re-adjustment yet because I decided to sold the trailer!

That's actually true, the rear on my van sag 50% more than front (and from increase a little bit) with the WD hitch install. That's surprising because the TW capacity of the Grand Caravan is 360 pounds without WD hitch (460 pounds with WD hitch) and my TT only weight 300 pounds tongue? I also feel like the rear end bounce a little too much when I roll over bumps on the road what make me thing the WD hitch doesn't make it job completely.

Unfortunately the former owner loose instruction manual and spare hardware coming with the Equal-i-zer hitch but I download the owner manual on manufacturer website but I'm still not sure how to re-adjust the WD hitch to transfer more load on front of the towing vehicle.

First of all I want to share some facts about the setup with you. First of all the Sportsmen is a very low profile TT and the ground clearance is VERY low. Secondly, the trailer hitch on the Grand Caravan is VERY low ground clearance too (in a sense it's a perfect match with the travel trailer... LOL), but for your info the former owner need to cut the Equal-i-zer shank from around 2 inch because the shank rub on pavement sometime! But it's not an issue because the ball height is actually good so no mater if the shank is cut, I don't need to move the ball height.

In the instruction manual of the Equal-i-zer hitch, in the troubleshooting section, when the weight transfert is not enough, they told do do two things :

1- Add more spacer washer until you reach maximum washer count. I just give a look and I saw 6 washers. Is that the maximum?? I don't know yet because it's not specified in the manual and I don't have any spares parts, so I can't know... but depending if 6 is the maximum or not, I'll find washer in any hardware store. But I just don't know how much washer is the maximum before STEP-2 (above).

2- Raise the L-Brakets from 1 hole adjustment on the trailer frame where the sway bars sit. I think I can do it because I'm not on the maximum height, but I'm afraid than this can be too much weight transfert thereafter? Should I need to remove some spare washer if I raise the L-Brakets height? I'm just confused at this point.

Your help will appreciate, thank you! I hope my english is not too poor and my explanations make sense! :-)

Thx!!
  • The maximum number of washers is the number that will fit on the pin going through the center of them. I believe that it will hold about 8.
    That is the best way to adjust the amount of WD to the front of the truck. The L brackets should be adjusted so that the bars ride flat on them and not on the leading edge. In other words, the bars should be about parallel to the tongue when resting on the L brackets.

    Also, once you get the thing adjusted correctly, make sure you tighten the angle set bolt on the bottom of the head so it does not allow the hitch head to pivot. It has a tendency to come loose and should be checked before every trip.

    I didn't take accurate measurement yet, but visually the front end is about the same (no sag at all), but rear is 50% lower than unloaded.

    When completely unloaded the Caravan front and rear are perfectly levelled BTW.


    Try to compare loaded without bars and loaded with bars. Measure to see if the rear gets lower when you remove the bars. If it does you know that at least some weight is getting transferred to the front. To get the perfect adjustment you will need to follow all the steps in the manual and measurements are a big part of it.

    What are the numbers for sag front and rear? Front should not sag at all. It should be higher or equal with or without the WD hitch.

    Front: In the manual's example front is 28" empty, 30" without WD and anything between 28-29" with WD is OK. Front still going up but not as much as without. This is how you know how much weight is transferred.

    Rear: 29" unloaded, 26" loaded and 28" loaded with WD. This number should be more than without WD but still less than unloaded. Rear end still sags; not as much.

    Can't help you on max washers. I also got mine used and I currently have 4 washers on it.
    Your camper hitch is 343# dry. It will be more than that with propane tanks full if they are in front.

    Mine is a 2011 and the TW was slightly lighter than new model. In the 2011 brochure and on the manufacturer label into my trailer's door the TW is also 304 pounds.

    In fact the rear end my Caravan don't sag that much, but it's definitely not levelled with the front. So I think I just need a little more adjustment, like fine tuning...

    Back of your truck should go down but less than without the equalizer. Something like midway between unloaded and loaded without the equalizer. Manual explains all the steps and the order in which to adjust things.


    Yes, but as I told I already read the manual from front to back and there's a little grey-zone about the maximum spacer washer count. They say to add more washer, but how many is the maximum? Since I don't have any spare washer (or any spare parts), I can't guess how many washer is the maximum before going to step 2 (raising L-Brakets)...
