But whats wrong with our current rear arms?
If you have a lift and you look at your rear tires, the are not sitting right in the middle of the wheel well. - Your new suspension does the trick - when you lift the KJ, your rear axle tends to move forward - or something like that - (people who understand what i'm talking about please chime in) so what a longer rear arm does - specially if it is adjustable, it will move your tires dead center on your wheel well - not only that, from what I heard from freejeep (who by the way installed aset) is that you get better performance offroad on the trails.
now, please don't take this as a fact - it is only my understanding.
Yep, the axle attaches from the front only. So when you lift, the wheel moves down and forward. With an adjustable unit, such as the Rubicon Express 3715, you are able to push the wheel back.
The problem you then encounter, as JeepinAl, myself, and others can attest is that you then change the pinion angle causing odd drivetrain harmonics. Al has built one but I'm not sure if his is adjustable, but I've got Andy from Carolina Rock Shop building an adjustable upper rear link that utilizes Rubicon Express builder balls. So I'm getting adjustability, plus increased flex.
I'm of the opinion that Rusty's missed the mark by making the arms fixed. It's nice that they put on swaybar mounts if you're into that sort of thing.
