Default Anti Wrap bar

So i've been looking to put one on my blazer and there's many different kinds. One has a shackle others don't. Is the reason for the shackle because you can still articulate or is there another reason?

to me the shackle idea is worthless. as it will still allow the axle to rotate since the shackle will just move forward.

am i wrong in thinking that? the axle doesnt move in much of a arc as it does up and down. i dont see a need for a shackle as it will jsut allow the axle to rotate.

im sure im missing something here as im half asleep.

The shackle has to be the same length and angle as the one on the springs for it to work properly

think of it like a lever. the force is pushed down throught the shackle, to the cross member. not forward and back. the forward and back movement of the shackle makes up for the length change when the axle articulates, like the slip in a driveshaft.

If it didnt work, their are a lot of well built rigs with about 40# of scrap metal on them then...

The shackle will still prevent the axle from rotating it, you just want to make sure it is mounted more or less verticle.
The only non shackle kind I have ever seen had a slip joint build into the body of the arm. The anti-wrap bar needs some expansion to deal with the wheel base change coming from the leaf springs.

The shackle helps with articulation but does not solve the problem completely. If you lay out the motions as the axle moves up and back, the shackle forces the axle to wrap slightly. With that, it now wraps in a controlled manner, rather than bouncing all around.

i like the second one.keep the shackle mounted out of the way. the seperation at the axle makes a difference and so does were it is mounted on the axle.

Definately go with a shackle setup. I found that running the shackle at about 45 deg. gives me the most flex both up and down and still controls wrap pretty well. You can put together a pretty nice setup with a ladder bar (as long as possible) and a regular leaf spring shackle (again, as long as possible). Make sure that you use the backing plates for the ladder bar so that you can weld it to your axle tube 360 deg. because there's a ton of torque applied to the bar.
