Topic: 4 link suspension on YJ

Well, it looks like the more I know, the less I know 
back to SOA!

[TahoeYJ]

I've thought many times about linking my YJ (Which if I ver do, is a LONG ways from now...)

My D35 started making noise this weekend, and I've already rebuilt it and geared it once, so I really don't want to spend sny more on it. I've got a Ford 9" that's been sitting for over a year in my garage and after some research, I've found it won't take as much $$$ as I thought to build it like I want. So I'm seriously considering a SOA set-up in the rear when I get it in, and keeping the front SUA until I have the time to set it up. Sucks because I just spent $180 on my DS yesterday to have it more or less rebuilt, so now I've got to spend even more to have it lengthened if I go SOA 

I've seen lots of SOA YJ's and CJ's and they seem to wheel pretty damn good IMO. The ride quality is better than my SUA set-up too :)

Well, keep in mind that when people say SUA, most of the lifts out there aren't that good.  The only two worth installing is the OME 2.5" and the Rubicon Express Extreme 4.5".  Other then that, you would want to look for something custom like National Springs, Dever, Alcan, etc...

Otherwise, if you want to go SOA, do a lot of research on leafs.  Personally I like my SOA/SUA since it's a good median between articulation and driveability.  No axle wrap either.

I am very happy with the SOA/SUA combo on the road, almost no body roll with the sway bar in use. If it was my only DD I might keep it that way but the offroad ability is too lacking. 4 link rear is underway and a radius arm front will probably happen next year.

Articulation was pretty poor.

3 or 4 link the front, radius arms are not the way to go. They bind to much. Causes problems in the long run with broke/tore brackets plus they don't flex as well as the 3 or 4 link.

I got plenty of time to figure out the front, just thought radius arm for streetability and an easier build. Four link fronts are a PITA to put together.

Looks like the rear leafs are too stiff.  That driver side rear doesn't look to be flexing at all.

If you want a radius design arm for the front, look into Cage Offroad's SAS kit for the Ford TTBs. I've got a Duffy design radius arm I'm going to use when and if I install the front D60. Duffy's you have to weld on the 'C' cups on the axle and use the rubber isolators to adjust your caster. Cage's you weld on the preset location.

It is non-adjustable for caster but I think it could easily be mod'd similar to the TJ's setup. You have a keyway bolt with a cam on it. The cam rotates against an edge and you tighten it once you dialed in your caster.


BTW, the frame end has a heim as big as my palm.....

They were, after wheeling a few times and adding new 6 leaf packs to the front it wasn't much better. So 4 link it is.
