those are for 63" chevys, ok which is better on the trail,some rocks, some mud and graval, i know the double is odviosly better on the ramp, but that is not the same as on the trail. what are u running and do u like it, would it be worth it to just go single shackle, rather than double shackle in the first place. and does the double cause any problems with unloading anythime or cause axle hop?:confused: thanx for your help.

I personally do not care for double shackles. They flex good but can cause bouncing on steep climbs. I have revolver shackles on my truck and i dont really like them. They were already on my truck when i got it and they dont even work. Does anyone know if revolvers are effected much by shackle angle. My angle is very little and i have nothing that should limit it, and they still dont unfold very well. If i cant get these working better they will be coming off and different springs will be going on. Anyway, you can only really decide by trying it for yourself. For more info use the search button, lots of info available.

I run dual shackles and a 2" block and was getting a lot of wrap on steep loose climbs. But I don't know if it was the shackles or the block that was causing it. Probably a combination of both. So I built a 2 link trac bar and that solved it. It works really well now, massive flex and no wheel hop. Flex isn't just good for a ramp, go for the duals. Also, you don't have to move the rear hanger back so it saves you a little work.

Don't run 'em, but with that long a spring I don't see the need
for a double shackle. Might be handy if you don't want to move
the mount.....but I think double shackles have more downside
than upside.

I have seen the double setup work very well. But it all depends on how the vehicle is setup. Each person does it differently and like how this feels or works compared to others. So in other words just go with the double shackle feel it out no moving the mount easy and should gain excellent flex. If it not what you were expecting or has problems you could always remove it and go single shackle? If I did it again I would try it out.

i already gave my 5 cents on the chevy-lowering shackle post..i ditched mine...i think its just a personal question you just have to ask yourself. :flipoff2:

I am trying to finish up the chevy swap on my 4 runner, and the shop where I am getting the welding and lift time wont let me take the double shackle out the door. The owner says in his opinion there is too much side-side movement of the axle. Also, with the 4 runner weight on these springs they are nearly flat, which I have a hard time believing. How the hell did they hold up a chevy pickup, when they are flat under a 4rnr?

Anyhow, I am ditching the double shackle and going with a dropped rear hanger, longer shackle and a add-a-leaf.

I ran the dual set up for a few months before switching the mount to accomodate the single shackle. I experienced some unloading on steep climbs and did not like the way the shckle transmitted noise through the frame.

I have been running the duel set up for 2 months now I have no difference in flex then when I ran one. I think Im going to move the rear mount for a better angle myself with the duel setup my angle is almost straight up with the chevy on top. I have a 91 with tha caged springs and I think the hanger in the back is wider and that has been giving me some problems.
