I'm currently in the middle of designing exactly this (minus the LS), been working on the design for over 6 months, hopefully I have something to share soon.

Oh man that would be super cool. Stockish width, good enough to drive down the interstate. (All I ever have owned outside of an 89’ Chevy ifs is solid axle pick ups, so I am very aware of what they are and what they aren’t unlike all the people who think coil jeeps ride “rough”…. Rough was front shackled leaf spring powerstrokes and rams in the 90s. Them were rough.

If the articulation can be in the ballpark of a stock to slightly modified TJ Rubicon that would be huge. Maybe 3-5” lift height. A TJ would be a good one to model after. That’s really all I want at the end of the day, I want my 99 Highlander to wheel like my brothers 04’ Rubicon does but have 5 seats and a rear cargo like the 4runner.

I know the whole world is a bigger is better mentality. The Internet is a buzz with the bronco raptor at 80 inches wide….. only way to get long travel on an IFS is to take the wheels a good long ways out I guess. I don’t understand why the OE don’t take a page out of the side-by-side manufacturers books. Maybe it’s a engineering impossibility, but rather than keeping the IFS outboard of a standard width frame rail, why don’t they bring it in closer like a side-by-side? That would get you longer travel suspension without having to have a freaking 80 inch wide vehicle.

That raptor is going to be sick in the desert no doubt. It’s going to be dumb to park just the like the f150 raptor. But raptors can’t physically fit half the places I go. The 3rd gen 4runner at 66” tire width goes where I want. Even the JK feels too bloated sometimes. Most of the time it doesn’t matter, until it’s time to think thin. I had one spot last year the mirrors had to be folded on both in just to clear the 3rd gen!

Anyways I’m ranting now. But man, a standard width SAS, that functions like a TJ rubicon, with off the shelf parts would be just perfect, for me at least.

Sorry to say but I'm going a bit bigger than you'd probably like. When you said 66"-68" I thought you meant WMS to WMS. I'll be running 99-04 superduty axles (I just measured the WMS to WMS to be 69.5" front and 68.5" rear, stock IFS width is 60.75" WMS to WMS), 39 or 40 inch tires with 4.5" BS wheels, the overall track width will be ~83" (stock is 66.5"). 3-link front with 2.5x14 coilovers, double triangulated 4-link rear with 2.5x8 coilovers and outboard cantilever suspension to produce 14" of travel without cutting into the cab. Trying to get it as low as possible, as much uptravel as possible, no compromises kind of design. Obviously this design is very particular to my desires, but nobody made or sold what I wanted so I decided to design my own.

It's been a ton of work so far and there's a lot of details left (nevermind the actual build!), but things are starting to come together. Here are a few screenshots:

Sounds fairly similar to what I ended up building on mine. My wms in the rear is 61.75 and the front is 63. So wider than stock but not crazy wide, about the width of an 80 series. Still tucks the 37s up in the fenders nicely. I spent the better part of a year designing the front and rear suspension to make it drive down the highway better than a stock truck would yet still be able to outwheel and flex most jeeps out there. Rear end I ended up making a cantilever setup with 2.5x8" coilovers that pull around 13 inches of travel, front is 2/5x12s. 3 link front and rear. Sway bars front and rear. I ended up with a 23" frame height so factoring in tire size it comes out to around 4" of lift over a stock 3rd gen. And with the turbo pushing about 300hp at the rear tires it should sing down the highway at 75 like its nothing. But again like the post above I had to design and build nearly everything from scratch in order to pull this off. That being said I used as many standard joints and service parts as possible so I can still find spares in the middle of nowhere.

@Black798 How do u like the AntiRock?

I am still doing final assembly so I can't speak for it's handling characteristics. But comparing it to the tk1 bar I got in the rear the arms are significantly thinner and the bar is also a much smaller diameter. But based off what I have read that should be sufficient to keep the suspension balanced with the rear. I'll know more about how it drives in the next couple of weeks after I get it put together

That’s going to be pretty sick!

Turbo’d and a solid axle….. awesome. Just awesome.

Everytime I see a 50-60 something guy in a new corvette I say sorry about your penis.

[QUOTE=Black798;3706505] Ok, I will take that into consideration. Johnsons Junkyard here has a few Toyota's still with front struts. I am waiting on the weather to get nicer so I can go crawl under them and do some measuring. I did get an instant 1.5" rear lift by removing my spare. HAHA that tells me my coils are toast.

My plan was to do something similar to dirtco's front build. I would like to tuck this D44 as close as possible and keep the center of gravity low. I have no intentions of rock crawling. Snow wheeling and taking the kiddo up in the mountains is all I have planned for this build.

When the weather gets nicer I would sure like to come check out your build. It is very impressive.
