I have seen a set from a friend a while ago on flat ground. Takes the bind off the spring pack but I was wondering if would really be worth the time and materials to make it. I have seen some in TTC and on bcbronco.com but I am thinking of my own setup.
I run all-pro and a buggie. took off one tire and the axle drooped and the buggie dropped like 5inches. I undid the axle while drooping (drive side) to add two leafs to it and suddenly the buggie went like 10 inches. Been wonderng if it would really help to have a pivot on the axle. I am not taking orbit eyes (hindsight is 20/20) I need cheep and easy. Any pix or input will help. BTW I have a three point setup as a track bar.
I think I will try this on my buddies 80 with IFS rear axle and trooper2 springs with an AAL cuz it don't drop very far. Just want input if there is any. Call on everybody this isn't just a toy think, but it is a rock thing...

I say do it. Anything that helps. I bet there was a time when people thought that double shackles were screwball, but lots of people use them now. And dual cases. I mean come on, TWO transfer cases, whoa man. <IMG SRC="smilies/wink.gif" border="0"> <IMG SRC="smilies/biggrin.gif" border="0">

Do it, but build it better than the Bronco one you saw - that thing looks SCARY <IMG SRC="smilies/eek.gif" border="0">

More bracing, etc.

A thought that I posted on the ORIGINAL thread about pivot spring perches, if you do this I would add a brace to the shackle or a track bar to locate the axle side to side. By the brace for the shackle I mean like Zuk did on his with a shackle with welded in crossbar then a tub welded to the side of the shackle going to a picot point mount in the same plane as the shackle mount so the shackle can not move side to side, this will keep your axle located very soledly

I was trying to figure this out myself and I think geometrically you will get your most twisting of the axle the closer to the frame you put hinge point(s). This can be seen with the orbit eyes. So my idea was that since I'm too cheap to buy orbit eyes use an orbiting shackle. The closest thing I found to that was tie rods on the 3rd gen 4Runners, specifically the short ones. Which has a Johnie joint built into each end. So I would use that in place of my rear shackle and get my twisting through the johnie joints at both the frame and the spring. Any thoughts, anyone? Does this seem crazy?

i have drop bars with a bushing in the frame mount and then a heim joint to connect to the shackle. i should've used high misalignment rod ends but i didn't. they still relieve some stress. at lest they did in the driveway. <IMG SRC="smilies/biggrin.gif" border="0">

you don't need 45 degrees of travel if you did get 45 degrees of articulation and say your rear end is 65" total width you would have 45" of suspension travel <IMG SRC="smilies/eek.gif" border="0"> a cool idea but not something that will happen

so whats realistic? Put a 3/8 inch plate as the flats and a half inch pipe maybee sch 80 40's kinda thin and then about 5inches wide cuz ubolts adn spare steel for strenght/ maybee 4.5 dunno and then how high does it need to be?Plus u-bolt nut clearances?

The L's are the u-bolts. You have to have a top and bottom nut regardless and they want to run into each other.

why not use 1/2" for the top plate and thread the holes so the plate that goes on top of the springs is held on by bolts, then weld the lower plate to the axle with good gussets and have no U-bolts

oddly enough, I have a piece of 1 1/4" .250 wall DOM sitting here waiting to do the same thing. The I.D. on this stuff is 3/4" This will also make a nice lift block for the not-so-lifting chevy springs.

The thing I was most worried about was the hinge pin/bolt getting sloppy over time and causing the axle to clank around as the pinion tried to rise.

the ones from BCbronco looked kind of skimpy to me and for $200 I don't expect any skimp. I intend to make mine 6-8" long with grade 8 3/4" bolts and zerk fittings.

post pics, sounds cool.

I've been running some custom 3" swivel blocks under hybrid Mazda springs. I used 3/8" for the plates, 2"OD DOM tube with a 1/4" wall thickness, 7/8" bolts, brass impregnated bushings inside the tubes and some cut down chev 1/2 ton spring bushings as end seals.
I've been wheeling all summer with these and they've worked great so far. I do run a top A arm on the diff for lateral control, so that is something to think about.

Any spring shop should be able to make you u-bolts. We have a place here in Sacramento that makes them from 1/4" to 1 1/4". I had some 5/8" bent for $8.00 apiece.
