+1 I have an ARB Snatch strap and it's awesome.

Lucky for me, no damage has been done, just stick in the ditch.
Hah, now that's funny. My wife has the same car and I'm making sure I have the right gear to pull her out if I need to. This relates to the loop/no loop question too - Most cars don't have a tow hook so how do you recover without looping the strap through itself (say, around a subframe)? I think the BMW has a removable eye but I wouldn't trust it anyway.

Yes, BMW's have a small piece of removable plastic on the front and rear bumpers. Just pry it off and there is a screw hole type thingy behind there. In the BMW tool compartment you will find an eyelet tow thingy in there that screws into the bumper. It's a great thing and I've used it many times!

In this case a chain is preferred, but a hook strap will work.

So, do you mean a chain as an attachment point for the recovery strap to the stuck car only, or a full length chain and no strap?

Probably not all that important for me but I would like to know. If she is down in a ditch I'll probably call AAA anyway, and if she is just off the road stuck in plow-off then it really won't matter as anything will work.

shackle receiver and $20. unscrew the shackle, slip in the recovery strap, screw the shackle back on the receiver and pull hard. Simple, safe, and cheap but still strong. I have had rusty products on my jeeps for YEARs and no issues. Also great customer service.

Re: Recovery strap hook locations

My buddy tells me its better to use your hitch and ball to pull someone out, as long as the hitch has at least a 2" drop or rise. He says these straight attachments put all the force on the pin and the pin is a lot more likely to snap and create havoc than a ball and hitch receiver with a 2" drop. He says using a drop receiver puts the force on the tow hitch package which is bolted on the frame. He tells me to save my money and just use my ball if i have to pull someone out.

Re: Recovery strap hook locations

No offense but your buddy is wrong. As the Rusty (cant speak to others) are solid pieces of steel the forces is exerted over the entire pin between the two points which are attached to the hitch. There is an even load across the whole pin under the receiver block and then even load on the two sides of the pin. As the 2 or more inch drop is basically extending the force (lever) it can actually apply a large load on the hitch which can be bad. Its better to have a load supported by two support members then by one like a ball. You also dont have to worry about the strap slipping off for any reason at all if it were to snap. It will stay attached to the jeep (unless the failure point is at the material is attached together or that part of the strap that is inside the shackle).

One thing your buddy should think about (not trying to be a dick) is ok you use this straight kind of recover system, where is it attached to? (the frame) plus there is a high load on the pin in a small area with a regular hitch/ball set up which can allow the pin to fail easier.

I'm sure there is a mechanical engineer in here that can draw out a digram which shows all the loads on both options.

Re: Recovery strap hook locations

Jeepman is correct, your buddy is not only wrong, but he is giving out dangerous advice that will cause harm. As has been covered here and in any reputable offroad recovery technique article, a tow hitch ball might be the worst recovery strap mount point as it is not designed to withstand those load forces, and will merely shear off and become a projectile.

A D-shackle is designed to withstand recovery loads in both materials and multiple pin mount contact points which distribute load forces.

A basic Google search will show the above if your buddy remains recalcitrant.

I use to be an mechanical engineer and remember doing all of the load, force, vector, etc diagrams but cant do it for my life now adays but I still undnerstand how loads are applied. Thanks for the back up
