Distribution Hitch Preload

I am wondering how much tension (preload) I can put on the weight distribution hitch "springs". Mine use chains attached to the spring or trunion bar and tension is applied by pulling up on the chains.
How much can the hitch typically take?
I have along lever tool to set the chains in place and can put the tension on, but at what point do I risk breaking something (springs, hitch cradle etc)?
To get the truck to sit at normal height takes a lot of spring tension. I typically have the tongue jack raising everything when I do the WD bars, but still is a lot of force.
I understand the hitch, so don't need instruction on how it works, just not sure how much it can handle.
Also, when I go through road dips the tension greatly increases, so needs to be considered?

Mine is similar to the Curt
  • The short answer is A LOT! Honestly without running the hitch through an analysis software on a computer your not really going to get an answer. You could probably have your hitch as tight as it will go and not break anything. At that point, you may have the rear wheels of your truck off the ground. I know it's not the answer you want, but unless you are way way out of adjustment, or have the wrong hitch for the weight of the trailer, you really have nothing to worry about.
  • That does not help any, I dont have information on the hitch, and would not be able to weigh anything related to spring tension. Some general knowledge on the subject will go a long way in the field…

    Also, something that might help is how much tension do others put on theirs. How hard do you have to work the tool to pre-load the bars?
    is it a one hand operation, or is it so much tension that if you let go the tool could break your leg in half?…
  • Most have a weight rating. Need to get the rating needed for the tongue weight.
