I thought i saw this somewhere but i cant seem to find it anywhere. . .

I am planning to do a shackle flip as well as a 3/4 ton axle swap.

Is there some sort of johnny joint, misalignment bushing, or something similar that you can use in the shackle to provide more flex?

it seems like i can picture it in my head and it would solve alot of the binding. . .
any ideas?
 
I think this is what you're talking about. K5 Krawler 50 did this.

exactly! so is that a standard johnny joint? did it fit in th kit or did it have to be modified?

are those home made shackles? how does it ride?

looks sick!
 
The joint will make the truck pretty unstable on the street, its not recommended for a street driven truck.

They do help a lot with flex though.
 
That flip kit was made by DIY4X with the JJ in it. Also the shackles are from diy4x as well

Like Mudder, said that is the DIY4X flip&switch with a jj installed by Kert. I looked on our site but didn't see them listed with that option, if it's something you are interested in you'll need to call Kert at the shop.

I was just thinking this the other day and also running one in the front spring eye REAR only does it still make it unstreatable i could see this being an issue on the front but the rear too?

If you run joints at both ends of the spring the axle will be all over the place, basically your springs will fold over and the axle will walk out from under the truck. You'd find this out the first time you turned out of your driveway, that's not even stable enough for a trail only rig. Basically the rig will sway a LOT because you've removed nearly all of the lateral stability from your spring setup.

If you run one joint at the rear of the spring, it will still allow the axle to move and will be squirrely on the road. Trust me, I know several people that have done it. This setup is ok for a trail only rig.

Would you run into the same problem if you were using those pivot type spring plates. IE: like on Stallion's old CUCV

Yep, but I'm only talking theory. I've never seen anyone run joints on both ends (or use a pivoting spring plate) but that should necessitate a track bar. There's probably a reason that people don't run that kind of suspension.

I have seen trucks with one joint in the rear and even that is pretty questionable on the street.
 
Seems like you'd end up with some of the same issues Steve and others reported with those folding shackles that were all the rage for leaf sprung Jeeps about 5-8 years ago. Said that under hard stops or quick lane changes it felt like the rear end was wobbling around and definitely wasn't a happy driving experience.

I was thinking the same thing. Weren't those the "Revolver" shackles for XJ's?
 
It might not seem rigth but would it not flop around just like a linked truck and with the right shock they are streetable and even at high speeds with no body roll?
 
Huh?
Four or more thoughts and one period = huh?

I think it would be a lot less sloppy on the road if the JJ was in the spring eye instead of the top of the shackle. That way it would allow twist but not swing of the shackle. I think you could even get away with doing both ends of the spring like that. Since the spring is still anchored flat on the axle, it shouldn't try to "fold over". My point is it seems OK to let the springs twist, but not OK to let the shackles try to flop back and forth. :thinking:It's all just speculation, so now I'm dying to mock this up.:D

here is a vid of a ranger linked and rolling 3 tires in a turn with a lic plate on the front. Are you telling me a johnny joint is going to be more unstable.

Just because link suspensions generally use flex joints or spherical rod ends (Heims) doesn't mean they will perform like a leaf sprung suspension using the same joints would.

A double triangulated 4 link gets its lateral stability from the angle of the links. Any other link suspension will get its lateral stability from a track bar. Link suspensions should completely control lateral movement of the axle, the reason that the truck in that video pulls a tire has nothing to do with what we're talking about.

Leaf sprung suspensions get their lateral stability from the bushings at each end (and hopefully) to a lesser extent from the spring itself. When you remove the bushing (i.e. by replacing it with a "johnny joint" or something similar) you rely on the spring alone to provide lateral stability. Because there is no bushing stopping it, the spring will twist during turns and allow the axle to walk all over the place causing poor street manners.

Again, I've seen, wheeled with and ridden in rigs with those exact shackles. IMO, they are not streetable. They make the rig very squirrely, even if at one end.
