Holy Scrub Radius BATMAN!!!
-G

Q: Holy Scrub Radius, Batman! How much scrub is there on these things?
A: All portal wheel ends suffer from the same problem – the presence of a gear case between the steering axis and the wheel mounting surface. The remedy is the use of wheels with deep backspacing. Our portal wheel end was designed around a HMMWV double beadlock wheel with 7 inches of backspacing. If you are running a 3.5 inch backspace wheel on a Dana 60 then using a 7 inch backspace wheel on our portal wheel end will get your scrub radius and track very close to where it was originally.
I love the build and how over the top it's becoming. I do think a couple things are counterproductive if he really wanted an ultra-reliable EOTW vehicle. The first thing you'd want is a KISS setup. That back suspension is everything but. I agree w/ others that he should have left it a stock length w/ a single rear axle. Just having portals under it with a nice linked suspension to control the wrap portals create (like having 5" blocks) would have been cool enough.
Ian has stated a few times on the show that parts should be readily available. If he's going to put in the TC that's been discussed to create the drive line, he just shot himself in the foot, because he's not going to find spare parts in an EOTW situation.
Finally, this thing is going to have a turning radius about the size of TX. He better armor the hell out of it because there's no way you're gonna drive it anywhere w/out bashing into stuff.
You guys think about this stuff too much...lol
I could careless if it's practical for any zombie/end of the world crap.

Haha, when you have an obsession, it's hard not to think about it too much
But as I stated before, I think it's pretty cool and can't wait to see the end product (and the tcase setup we've been talking about)

zombie obsession?
I'm looking forward to seeing it all done too. Hopefully he gets some decent film offroad with it.

@runamok151 the rear suspension isn't really that complicated. It's a leaf spring and some links. The links are all the same length so a spare is easy to carry and the leaves are stock length front 6" springs. True, the slider boxes and pivot point are a little different from the norm, but I think what some people are missing is that the parts and design he is using are meant to eliminate the need for readily available replacement parts. If everything was stock, you would require support . . .
I saw the episode and I got the uniformity part. But it's a hell of a lot more complicated than a set of leaf springs and anti-wrap bars. If he wanted to keep parts universal he should have figured out how to mount the same 2" lift spring packs all the way around and then he would have only needed one spring pack for a spare for all four corners.
looks like its on the back burner of the tv show extreme 4x4So what happened with the suburban?
