I was looking to buy some shackles. I found that they were rated for strength by the working load limit (WWL). They were about half the price of 4 x 4 shackles rated for 10000#. But is that 10000 pounds the break strength? A forged 5 ton shackle (rated by the WWL) was very big. It has been some time since I have bought anything like this. The guy at Fastenall didn’t know the break strength, just the WWL.

 

Hi there,

I'm also going to be getting some for my new bumpers, probably through these guys:

They are not a advertiser here.

Their alloy 3/4 anchor shackle is rated for 7 tons WL, breaking load is 5:1. A 7/8 shackle WL is 9.5 tons, also 5:1 breaking load. Same ratio would apply for their 5 ton stuff too. I think marine supply and logging supply stores are the best place to get this stuff. Much cheaper than a 4X4 shop it seems.

It's my understanding...from this very forum, that off road d rings and agricultural d rings are two completely different animals as far as strength is concerned. Stick with the off road ones. Although I don't know all of the details, I know that the off road d rings are made for what you intend to use them for.

 

Hmm, I can't see what the diff would be other than price and packaging. A screw pin type anchor D-ring rated at 7 tons WLL, is well, 7 tons. Even if you used a 12k winch, you still have a full 2000 lbs of lee-way. If loggers were using 3/4 inch 7 ton D-ring for work, certainly it would be fine for pulling a Jeep out of a mud hole. The 3/4 in shackle listed on the web site I linked to are about half the price of the Warn ones at the local 4X4 shop. Plus too, if you were to use hardware that is for industry, shackles, snatch-blocks, etc. I'm sure OSHA makes sure the listed WLL is the real WLL. I haven't verified that, but if a 8 ton snatch block busted at a job site and killed someone OSHA would be up the manufactures butt.

I use D-rings in crane lifts. Believe me when you are lifting units up four or more stories those puppies had better be overated. Lives depend on it.

D-Rings are not bungie cord rated.

 

I promise you there's a difference. There was a pretty active thread about this a while back. Something about how the two different shackles are rated differently. I can't remember. But whoever it was that brought it up was RIGHT. Call David at Northridge. He can tell you for sure. I thought the cheaper ag ones were a deal too, but they're not made for off roading. A broken d ring can kill the shit outta you, so you need to make sure you got the right ones. Know what I mean?

 

not neccessarily, OSHA might be up the job site's ass first to make sure the equipment used was correct for the application. ie if someone on the job site were using 5 ton d rings to move 10 tons of material the manufacturing company would not be bothered.

 

O.k., I think I found the thread you are talking about https://www.jk-forum.com/forums/show...t=4x4+shackles Reading through, it was discussing how agricultural equipment may be die cast while 4x4 equipment is forged. I also understand that a shackles on a combine or crane wouldn't be under the same load dynamic as a H2 getting yanked out of a mud hole. However, a drop forged alloy 7 ton rated shackle, with a failure ratio of 5:1 (that means it'll take 35 tons to break) will, I'm sure, take all you can throw at it. It just won't say Warn and it'll be cheaper.

Also, consider this, logging IS off-road and more than just "Trail Rated".

Great discussion BTW,

Understood and agree, but if it failed during its intended use and under rated conditions....Then a visit from a kindly helpful government agent.

I hope you're right. I mean.....the possibility of your head cracked open and your brains splattered out all over everything.....if that appeals to you, then by all means, get the wrong shackles. ...and I'm not sure the ones you're talking about are wrong, but it doesn't sound like you're 100% sure either. With the possibility of brains splatterin, I'd wanna be DAMN sure. But that's just me.
