Shackle strength physics

[Old Jeeper]

Maybe I'm paranoid, but I wouldn't buy from a vendor that uses a divisor of 3 to calculate work load limit. 4 seems to be a much more appropriate divisor to give you a reasonable set of expectations.

It depends on the expected end use. Most low level stuff will be 33%, you get it a. Home Deptot and Lowes etc.

Now you get up in SERIOUS stuff that failure would be catastrophic and that where you find the 25% factor. Even at this I have seen steel cables break working on a 64 Ton.

Soft shackles can take hard hit and heavy pulls, if you buy a quality ones. Your typical hard shackle D-Ring that you see on Jeeps are usually rated at 18,000 pounds. The ones I use are rated at 32,000 pounds.

I do carry a hard shackle with me because there are times that there is nowhere to hook a soft shackle to because of sharp edges.

If you watch Matts Off Road Recovery Youtube channel, you will see him hook soft shackles to Class A motorhome and at times semi trucks and pull them out of mud and sand. He also does hard runs to the end of his kinetic rope while doing these recoveries.


The secret is to buy quality products. Recovery gear is not a place you want to pinch pennies.

Speaking of that and Matt, I think I've seen 2 video's where matt breaks SS by connecting them where he should have (and eventually did )connected a bow shackle. The attachment point on bumpers doesn't have rounded corners, it's made for bow shackles not SS.
