i had this idea...

this is my cad rendering of my idea for a 3 link set up. im going to make the brackets just like they are here, these pictures exclude the trac bar im already running. does this seem like a good set up? i think wranglers run something similar to this.

also, i was thinking...and my articulation is limited by my shocks...my springs will go further than my shocks want to let it. so, i came up with this idea of a shackle that the shock mounts up to, (look in lower pic). when normal driving il have the shackle bolted down...but when im slowly crawling or need to get more drop from my axle, i can unbolt it and let it swivel when it needs to.

gime suggestions or opinions!

i'm not 100% sure but i think your top link needs to be over you diff.

nice model
you're not talking about getting rid of your trackbar, right? you definitely need one.

I think you should just get longer shocks. I've seen setups like that for coil springs and revolver shackles or buggy spring setups for leaves. but I think you'd want your shocks mounted solidly. Those pivoting brackets would slap around quit a bit.

Is the purple piece to mount coils?

here's one of my crazy ideas

that looks awesome man. did you cad that render by yourself? it looks like itd perform like a wristed radius arm set up. so, yesterday i talked to a guy who knows suspension...and he talked me out of this crazy 3 link trac bar set up....and what i think im going to do now is a triangulated 4 link, make a high mount on center of axle to throw angled bar back. that will eliminate my trac bar altogether.

currie axles have mounts for 4 link triangulated....so it cant be that bad a set up, what you think? im trying to find the most efficient way to do this link set up....i can cad any ideas, n fab....but its the experience with this suspension stuff i need...

trianglulated is gonna suck if your still running mechanical steering. do a search on int net for 4 link fronts and youll find no one runs it unless you have full hydro steering.

triangulated 4 link can't be done properly without a LOT of modifactions. IE, the entire engine crossmember would have to go and a decent amount of lift required.

The other one looks cool too. Although running a dual bushing setup could make the frontend feel a little floppy.

I've seen this mentioned a few times, although I'm not sure how it would differ from a leaf-sprung setup, which also moves up/down in a straight line.
If the drag link is dead-horizontal, I don't see how bumpsteer would be so great as to cause a problem. Can you elaborate?

(is it because of how the axle pivots maybe?)

Why not just buy longer shocks?

Here's a 3-link similar to what you posted. Rode in the truck and wheeled with it many times. Flexes great, yet to break any links or brackets.

On a leaf front end with out a track bar, (old chevys, pre 1980 fords, big rigs,) the pitman arm moves front to back, NOT side to side, and is connected to the drivers side wheel. The pitman arm end is near the front spring hanger, and the draglink goes back to the steering arm that is pointed in from the tire if u can imagie it. Look at a big truck next time ur near one.

The newer leaf spring front end trucks ( 90s f 350s, superdutys, jeep yj?) have a track bar and the steering system is like a coil front end's steering.

RebelAssaultTruk-
I drew that using Rhinoceros 3d, its pretty easy to use and you can get a free version to play with.

It's not finished obviously, needs a track bar and the rest of the front axle and finish the shock/coil mount stuff.

and yes, it'd be like a pivoting radius arm setup using ford radius arm bushings.
like this

Not really a wristed arm as that is a different setup

I think a triangulated setup would be the best for a rear axle, but for the front I think you'd definitely need a track bar to avoid steering issues.


Here's a different version that would be more of a real 3-link

And here's a rear axle wrap bar design:

I was on a skull design phase a while back since my truck has sort of a skull theme. see:

but I ended up doing my SAS with leaves since it was cheaper, but I may build something like that in the future.

Huge numbers of people swap that push-pull style steering out for crossover setups without bothering to install a trackbar and have not had an issue (I see this on Toyotas most often). Many guys I know ditch the trackbars on their YJs too.
I'm just wondering what makes it so different if the suspension is linked vs. leaf-sprung being that both travel up/down in a straight line.

Travel is the difference. Most of the leaf systems dont run the same travel numbers of a 4 link.

I guess that would make sense, although I've still seen some pretty good travel #s (not just flex) come out of leaf setups. I'll butt out now though, carry on.
