Badass project....Id change up your lower wishbone though....doesn't leave much room for articulation...any you get will be the bushings or the tubing flexing. Adding the bags on there just make it suspect to more stress risers. Just a thought....try putting the jack under one wheel and see how much travel you get before the whole truck twists. Itll bind much like a 2-link but worse...as it is more structured than a single piece of 2x2.

about your comment about my lower wishbone, then can you explain to me how a regular fourlink with all bushings works? your gonna get just bushing travel with all none himejoint suspension. everytime someone mounts a fourlink with the tabs angled, theres tons of stress on everything... also, my truck is only front to back, there is no side to side. And if in the end, it doesnt work, ill rip it out and do it all again

And if in the end, it doesnt work, ill rip it out and do it all again ---------------------------------------------The difference between a standard wishbone and yours is the dual mounts on both ends. On a standard wishbone most people use a single bushing on one side....Like this.... Since yours has 2 on both sides then there is a ton of twisting motion that is going to be put on the entire wishbone...not just the single bushing on one end. That twisting force is gonna attack the weakest link of your wishbone...rather it be the tabs, mounting points, or one weld that is not as strong as the others. It doesn't matter that you only have FB....because the roads you will be driving on arent level. Everytime you go through a ditch, an uneven driveway, or take a corner fast and cause body roll there will be a ton of twist on the wishbone. I'm not saying it won't work....im just saying I would keep an eye on it. That's alot of twisting force......

Its hard to explain with a keyboard....just put a jack under one wheel and jack it up.....or drive one wheel up on a ramp and I gaurantee you the opposite wheel will follow or the entire vehicle with lean.....Better yet if the wishbone is not attached to the axle...try twisting the wishbone as if you were going through a ditch.

so... in the pic you showd up top, lets say the lower ink bars are both bushing rod ends... when that truck hits side to side, whats gonna happen to those lower links, are they gonna twist?

I'm not an expert, but it seems like both setups shown will have articulation limitations. I'd want a super-pivot or a heim on at least one end. I'm sure this titan will be fine for what he wants. Glad to see another Titan on the ground. You did more in one weekend then I've done on my Armada in a year!

The setup I posted actual has super pivots at the axle on the wishbone and the lowers. It hits stupid sides....Like I said it's hard to explain on a keyboard. Im trying to come up with a better way of explaining it.....other than putting it on a jack or ramp...its hard to explain what i'm talking about. Sorry....I guess i'll shut up. Sorry I bothered ya....

i can understand what jerry is saying. with 2 busings right next to each other, you've made the pivot point like 8" wide and w/ the wishbone braced that well its acting like 1 solid plate. it will limit articulation, just something to watch for.

its a bad drawing but i just did it real quickbecause you connected the lower bars you now have made 2 pivot points act like one long pivot point witch will put a lot of stress on the mounting points on the frame and will limite side to side movment.
