Is there such a thing as too much drop?

Mine is a dead stock 4wd 2016 Ram 2500 cc/sb. I think it has a class 5 receiver, 2.5 inch. From top of receiver to the ground is 26". From the top of my level TT to the ground is 17". I have a new drop shank from Curt, the only one I found with enough drop to get me down to 17" to top of ball.

The WD hitch is an eazlift, the the new drop is 11.5 to the top of the hitch and 17.5 to the bottom. The top of the ball is at about 8" from the top of the shank, but when mounted into the sleeve and hitch it's only 16.5" from the ground. The sag caused by slop in adapters causes almost 2" of additional drop.

I bought a clamping system that uses two square "u" bolts and a big angle section to tighten all of the wiggle out but haven't used it to see if it works very well.

So, with that much drop, and with all of the front to rear, side to side stresses that will be applied during towing, can the excessive drop required to get to level cause undue stress on the receiver and its mounting system? It's currently a 6000# load from a6800 GVWR TT, but in a few years we'll upgrade to something bigger. I will most certainly consider tongue height of any prospective TT's while shopping should we go again with TT over 5er.

  • I had no sag on my first attempt with the old drop and new truck. Last I checked the tongue was right at 600 pounds. I'm going to try filling the fresh tank to get some more on the tongue because it's barely 10%. Might be okay with the new truck but it floated a lot last trip with the old 1500.

    Lord knows I don't have to worry about being overloaded.

    For all of the slop I found and bought this little dude. Supposed to prevent the wiggle but I haven't put it all together.

    I'm hoping to get it all together this weekend and go for a test tow and weighing. We have a nice little circle that take us out to I-40 for a few miles to a truck stop and then back toward home via old 2 lane state highway with big hills and some good curves. Should be a nice little shake down.

    I find the part in red concerning. For a 2" change in height that is a lot of play/slop. Those loose components will constantly be beating against each other while traveling.
  • My new Ram 2500HD was high in the rear but sagged a lot when hitched.
    And following Ram's WDH instructions (reducing front end lift buy 1/2) didn't raise the rear that much. I ended up raising my hitch head to the top shank setting to level the trailer.

    When I pull the trailer with a non-WDH, I actually need a 3.5" rise to level the trailer because of the rear-end sag.

    My trailer has a high tongue weight though; maybe 1250# and I'm using a 1400# Equal-I-Zer hitch.

    Guess yours is a lot less tongue weight?
  • Receiver doesn't care, it still carries the same vertical and towing load. What matters is the rating of the drop adapter, needs to be class IV (7500#) minimum.
