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!!
  • Here's the first try on readjusting my Equal-i-zer WD hitch. I add one more washer, but as I told my washer are slightly thicker than the factory washers, not twice thicker, but I would says 1.5x thicker. So the count is now 5 factory washers + 1 thicker washer.

    IMO the rear end is still sag a little bit and front raise a little bit. But I don't know if I can adjust it better than that...

    What is your opinion? Is this adjustment good enough or you would try an additional washer on the WD hitch shank?

  • Those bars are there for safety. You have to forget about how it looks and follow the instructions.
    It is fine that the front raises and the rear is lower.
    The problem is that is the front raises MORE with the bars than without you are removing weight from the front and this will create problems with steering in emergency situations.
    I don't think there is any way to lower the rear MORE with the bars than without but if you did it could cause problems with the payload carrying capacity of the rear axle.
    Find a level ground; where you are now seems fine. Remove the bars but keep everything else and measure. Then put the bars on an measure again.
    If you can still easily put on and remove the bars without raising the jack they are probably not doing much.
    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.
  • I'm late to this thread, but it looks to me that your L brackets on the trailer tongue are low. Bars should be closer to parallel. That may be enough to shift more weight to the front axel.
  • Well I did this test before, but I did not look at the front height, but I know that if I remove the bars, the rear sag almost flush to fenders! So the bars really do the trick I would say.

    I'm gonna try to measure it tonight if the weather clear out. I had to hurry because the place where I took the pictures is perfect for measuring and it's closed by monday and tuesdays nights, but tomorrow it gonna be opened by the night!! :-)

    I where pretty sure they are almost parallel, but now you are telling this, I'm not sure anymore. Maybe it's a matter of perspective? Here's a zoom in on the hitch...

    But maybe I consider the bars are parallel with the A-Frame of the trailer, not really parallel to the towing vehicle in that case...

    Definitely sounds good. Now you just have to confirm that you are not transferring too much to the front. Probably not but it's a quick measure and then you know for sure.
  • Agreed, it was perspective. Bars look good and parallel to trailer tongue/A frame in this photo.

    As long as the bars are riding on the flat part of the L-Bracket, you should be good to go. What you don't want is the bars riding on an edge of the L-Bracket as this will reduce the friction control.
  • It looks like your bars are parallel, so I would go ahead and add another washer to the head. That should put you where you need to be. Then go out for a drive and see how it feels.
    Good luck
