Rubicon Automatic Sway Bar Disconnects Lift Question

I have a 2007 JK Rubicon Unlimited and I am looking at buying the Jeep JK Wrangler 2.5" Suspension lift from Rough Country and I am wondering how it works with the automatic sway bar disconnects on the Rubicon? Does the lift disable the auto disconnects? Or mess with anything to this sort?

I have a 07JKUR with a 2.5" SkyJacker lift that came with new sway bars. On mine I first have to pull the pins that hold the bars, then push the button in the cab to release them, then take them off. I don't know of that helps or not.

The rubi's sway bar disconnect system is in the center of the bar, not the ends of the bar like with aftermarket options. So as long as you have longer sway links on the ends then I would guess the auto disconnect system in the middle of the bar will still function as normal.

I am planning on keeping the original sway bars

Sorry for the confusion, I mint to say sway bar links. I'm still learning all the proper part names.

Yes... As long as your sway bar stays parallel with longer links it won't bind and function as normal.

Hi Sevs,

Not sure exactly which rough country 2.5" kit you are ordering but they all function basically the same as other aftermarket kits.

I personally have an '07 Rubicon JKU as well. The electronic swaybar motor controls whether the swaybar rotates as a solid arm or independently. The motor will not disengage the solid swaybar rotation in an electronically disconnected state unless you are in 4 wheel drive.

With the rough country kits that require swapping out the swaybar arm links, this is due to needing longer links to connect the swaybar to the axle in a horizontal plane from front to rear of the jeep and the link running vertical from the swaybar arm down to the axle.

Here's where it becomes an issue with the Rubicon electronic disconnects and aftermarket swaybar links that I have seen in person happen to three Rubis. With some kits, the links tend to be right at the required length with out any extra extension to them (8-10") depending on the lift size. When you off-road through light articulation conditions the electronic disconnect works and functions as designed with no issues.

However, when you get into areas that require more articulation, without limiting straps the swaybar and link can "flip" from the upside down/backward "L" position to a normal "L" position. When this happens, the link lays right over the tie rod. Then when you turn your steering wheel, the bolts/bracket on the driver side end of the tierod snag the swaybar link and bends them.

This is why you see a lot of guys either running the Rubi e-disco for normal trail use along with manual discos for more difficult trails (like I do), or sell their e-discos all together and buy other swaybar systems like the Currie Anti-Rock system.

Sweet thanks for the info! That's what I was looking for!

Hi, I'm a new jeep owner, I just got an '08 Rubicon with a 6'' lift and 38's. If I install quick disconnect sway bar links I should be able to do extreme terrain (by manually disconnecting them so I don't damage them) and still use electronic disconnect for not as rough terrain? does this make sense?
Also wanted to ask how long do 38's MT last (how many miles? I have goodyear wrangler kevlar) and what kind of wear and tear do they do on the engine etc? thank you.
