if you do use shackles atleast get crosby or green pin and try to keep that money out of chinese hands. then again maybe im the only one who thinks like that
I prefer shackles only because I like to take them off when I know I won't be using them for an extended amount of time.
But WOW.. Lots of bad advice here. If you decide on a shackle you MUST use a "bolt" type shackle. Every other type of shackle show here on this thread is a "pin" type. Pin shackles will generally shear the threads of the pin with much lower amounts of side load compared to the bolt types. You also want a capture spring or cotter pin to protect against losing the bolt and having a POUND of metal vibrating off YOUR truck and killing somebody's kid because it's bouncing down the road at 70mph. A pin-type shackle can (and will) come loose and fall off. I went with 2 USA made CM 5/8" 4.5Ton (minimum 54,000lb breaking limit) shackles. This is what you want:

Interesting.
So a pin type is the kind that screws in; has one pin that screws to the aft side?
I run mine just like in that pic in my last post I quoted. Always figured it was rated for whatever kind of load it takes but I kinda see what you mean.

I tightened mine with pliers so A) they wouldn't come loose, and B) theft protection. Someone would have to have a set of pliers to steal them.
For my application (bad advice ) I have found the G 209 screw pin galvanized anchor shackle to be plenty adequate. The friction in the screw pin design is adequate. In the application of trailer chains, the shackle pin is not subject to constant oscillating movement while loaded which could eventually rotate the pin out. I remove and re-install them often. Of course I have to do my part and tighten the pin with a tool when installing. If only hand tight, the pin could vibrate or cycle itself loose. For my application I see no reason to have to replace cotter pins every time I re-install the shackles.
The G-2130 is the "bolt type" with the retaining nut and cotter pin. The 2130 is safer by design (and used for offshore lifting) but you have to use the cotter pin which isn't as friendly for removal and re-installation (for me).

Everyone has their own opinions and experiences. My experience is that the pin type has worked for me since at least 2016 with no issues. After the effort I had to put in breaking the pin loose last week (after 2 years on the truck) when I traded the truck I'm not convinced it would have come loose and fallen out.
