So I ordered a pair of Crosby 3/4” shackles with 7/8” pens, I can get them to fit but would have a better fit if I shaved down the top of the inside eye of the shackle. Right now the inside eye hits the bottom of the receiver hitch, if I shaved off just a hair of the shackle it would hang better, any reason not to do this? Or should I return them and find something else? I prefer these since it is easy to remove when not needed. This is with the 2.5” on a 7.3, Thanks for the help.

I have the same issue. Try putting the shackle in with the pin inserting from the bottom. (I haven’t tried this yet but I saw someone else do that. I tried taking down the casting on a cheaper one of mine and it still wasn’t enough not to bind.

If I were dead set on those shackles, I might try and shave something off of the receiver before I'd modify the shackle. The receiver has more metal to lose than the shackle. Taking metal off of the shackle would have a bigger impact on the integrity of the shackle than it would taking it off of the receiver.
 
Thanks guys maybe I’ll try to find something that fits better

I had to reread this, I didn’t think about it at first but you’re right. I think I’m going to try them this way and use some safety wire to keep the pin from possibly twisting out. Thanks again
 
Not to be a downer....just know a shackle has to de-rated by 50% when they are pulled from the side like you are using them up. They are made to pull from the pin straight down or at a 45 degree angle at most. Maybe you could get a large enough shackle even with the de-rate to work. Just would hate for anything bad to happen. Good luck.

Yes I know depending on the type of shackle, side load can possible decrease strength rating. However, if I place the pin up through the bottom the chains would attach to the bottom of the shackle. If there were a failure the trailer chains would then be pulling straight on the shackle not the side. If I were to install the pin through the top then in the chance of failure I could be side loading the shackle. At least this is how I see it working in my situation. I am going to attach the shackle to see how it sits first before using, but thanks for the heads up.
