My trailer chains hooks are not large enough for the hitch on the Super Duty. I ordered these but they are slightly too big to fit. Any ideas?

I purchased these for my truck. It's a popular option.

Following. I bought
these these
from Amazon but they do not work. The eyelet end is too tall to fit up inside the receiver cavity and the bolt won't align.

Do they fit if you remove the plastic protector?

That’s a big clevis! Stop by your local John Deere dealer. He’ll have some smaller ones so you can see if they fit before you buy them. Probably cheaper too! I got lucky and all three of my trailers have hooks that fit so don’t have any first hand knowledge!

I replaced the safety hooks on my trailer with these:

I just put bigger hooks on my chains...I stopped by a trailer dealer and he let me try some different sizes to find out what would fit.

A 5/8" shackle is what you want, and is what I use.

YES!
The 3/4 were a hair to large. Had to visit 2 TSC stores to buy. One was out of stock.
Some day will paint black, for now they have the mini-pearl tags flapping in the wind...lol

I think I got mine from Northern Tool. Amazon/Ebay is always an option too...more options, black/zinc/chrome, etc...

Also, I would suggest tightening the pin with a pair of pliers. This will keep sticky fingers from easily stealing them in a parking lot.

Some of the shackles suggested have load limits <7,000 pounds. Assume we are towing 10,000 pounds. Since one chain will be shorter than the other there will be 10,000 pounds on one shackle rated for 7,000 pounds.

Is there something I don't get?

Might be wrong but I saw it as having to cover roughly the tongue weight + some given the shift in weight distribution if the trailer becomes unhitched. With 1500 lb tongue you'd need over 4x the amount of weight shifted forward from unhitching to get to the WL capacity of the shackle. Then again now that I think about it.... I guess that doesn't cover the impact load exerted by unhitching...

To be honest I was also considering you'd share the load between two shackles... Didn't realize chains were different lengths - is that standard?
