Thats why you should always use a shackle with a greater rating than what is needed. 4wd often means winching or pulling at different angles on a shackle. same as when it is connected to a pulley or recovery point. Large shackles might look like overkill on some jobs but at least they should do the job comfortably..Originally posted by my.paj View Post

With proper set up, in most cases you should be able to avoid side loading a shackle when recovering stuff.
Shackles are rated for lifting plus have a decent safety factor built in. When used in recovery situations with a winch (slow and steady) a rough estimate is that you can almost double the capacity of shackles etc.
Snatch recoveries are a bit different due to the forces imparted at the time of the snatch due to the somewhat impact type loads2010 NT Activ, DiD+lazy shift. Bushskins+Boo's, Kings springs+Monroe shocks+Firestone Airbags, MM towbar, MM nudgebar.

I wonder if this test has been done on the synthetic nylon connectors we are seeing entering the 4wd market.
Where a vehicle has to be pulled sideways, either by immediate "snatch" procedure or by slow exerted pulling forces i.e. with a winch.
It maybe a case that the nylon synthetic only being used for basic vehicle recovery and not for more complicated scenarios.Comment

I would be more than happy to go even larger on my shackles for towing the van but the holes in the tow bar and associated safety chains only allow a certain diameter pin through, thus limiting me to a shackle of a certain load limitComment
