The whole truck and trailer will disintegrate before a 3/4" shackle comes apart! Breaking strength somewhere close to 20tons X 2 shackles.
Look at the other parts of the trailer chain/ attachment system. Guessing it's not 3/4" cable and 1/2" plate connections.
Those shackles couldn't be more overkill. They'll work fine.
Isn't that the truth LOL. You have to love these forums, complicating the uncomplicated since 1852. People may want to take a good look at how those chains are connected on the trailer end. Most I have seen simply have a short piece of 5/16 rod slipped through the end link on both chains, and then it's welded at each end to the underside of each main A frame member. That's usually done by some nose pickin meathead who was hired at Lippert the day prior, and whose previous experience with metal was opening Coors Light cans.
These will also get the job done in the OP's situation if a shackle is not handy in a higher indicated weight capacity than shown. Or a combination of both which I had to do on my 2015 GMC.
Now let the debate begin on how the world will come to an end, a catastrophe will happen, someone will sue, it's in violation of the Interstate Commerce act, so on and so forth etc.
