Rubi sway disco - on the rear!

[chorky]

Curious if anyone knows anyone who has or attempted to put a rubicon front sway bar disconnect on the rear. This would be a slick setup. Although Im not sure if there is a width difference between the front and rear - probably. Also not sure if there is even space to put the disco in the rear.

I’ve read threads about this on the wrangler site. Didn’t seem to be of much benefit?

Just to make sure my reasoning for esploring this is understood, I do not care about maximum ‘flex’. My intent for this is not to rock crawl at all. Its purely about comfort. When the front sway bar is disconnected in my JTR, the ride on a bumpy undulating surface is significantly more comfortable. Only ruined by the rear end swaying back and forth as the rear dips and bumps over what the front just traversed. This happens because the purpose of an anti-sway bar is to prevent body roll. So for example by lifting the right rear tire above the left, force is transferred to the left just as to prevent assumed body roll to the right tire as the right suspension is being compressed. Similarly, when on the highway and turning left, forces attempt to push the body over to the right as if the right suspension is being compressed - so the anti-sway bar provides resistance to this in A similar way as if the right suspension was simply compressing. Now imagine if you will there was no anti-sway bar. On the road obviously it would be dangerous. But on a bumpy undulating surface, it would allow the suspension to move up and down relatively freely. This is what the anti-rock was designed for and teraflex system operates a similar way.

In my OBS 350, front and rear sway bars were just removed entirely and for being such a big truck that thing floated like a cloud.

I have seen this. Actually maybe it was a different video. In the video I saw a while ago the argument is that sway disconnects in the rear addition to just a front disco or front anti rock provided no additional flex than just one disconnect. But a very key point here is I am not after maximum flex. .I dont rock crawl. This is entirely from a comfort perspective. Flex from thefactory suspension is sufficient to me. I am after offering the factory suspension more freedom to cycle, compress and decompress un-restrictive - which is the purpose of the rubicon front sway disconnect.

Your reasoning is sound, but how much lift are you running? If more than 2" you may benefit from a rear trackbar relocation bracket. It really helped the back of the jeep roll over big whoops without banging you around.

I am stock with no lift currently. But I am planning everything on a 2-3” lift within the next 4-5 months. Likely figuring a solution to this will take longer. I have already considered the apex option but I think the rear end has too much travel to successfully work with those.

I may, after breakup, try and post some videos of stock vs front unlocked vs front unlocked and rear physically removed to visually show the difference. I have experienced having no rear sway-bar (which essentially is the same as having a electronic disconnect) and it is a huge difference in ride comfort for slow to moderate speeds.

Also, having an electronic option, allows for easier reconnection if one is traveling through a stretch of off camber stuff, for which having sway-bars engaged offers a huge positive stability and safety factor

I think you're going to end up with a really sloppy ride to the point of maybe being difficult to control safely at speeds. If the rear is floating it could very well end up the tail wagging the dog... and if the front is going different ways separately could get very dicey.

Yes this is a good point and valid but it would not be used on road. This would be for cruising forest service roads, undulating surfaces, off highway stuff.

How fast are people trying to go??? Seems to be a consistent theme of go fast. There is actually a speed limit of 25 on forest service roads and FS law enforcement will give tickets for excessive speed.

 

[mx5red]

Could find another e-disco and wire to aux pretty easily but may be hard to mount.
Can you do a trial run? Just unbolt one side and see how big a difference it makes, if worth putting more time/though into.

On a forest road I would definitely not be looking to be getting loose, and 25 year thats plenty to be concerned with. Try it but be careful.

You could swap out the rears for very soft spring and support them with airbags to stiffen them back up. Then deflate them as needed... like tires.

Also are you airing down low? That helps tremendously.

Maybe throw an antirock in the rear? A couple guys on the wrangler side run them, but I think they make a version for the JT.. if not, shouldn't be terrible to adapt.

I also have vestibular deficit from brain surgeries so high speed is not my thing and comfort and stable visual horizons are a good thing to help prevent migraines and vertigo. This, for me, is 100% about comfort

Yeah thats exactly what I was thinking about doing. But I agree with you that mounting could prove to be difficult. I was going to do a test by unbolting one of the links once the snow melts but I am 90% confident it will work since my last truck didn't even have the sway bars at all

Yeah I have thought about that. Or looking more into the tera flex system since supposedly it is dual rate. But I will be fairly heavy so not totally sold on it yet. I have front antirock on my TJ and it is great off road but on highway is definitely loose. Im just not sure that I want to be that loose with the JT since it will be loaded with a RTT

Fab a simple manual quick disco? Should be fairly simple.. would only need to do one side since we aren't talking about articulation, just uncoupling the rear from the frame.

I understand the desire for electronic control. You’re obviously on the right track as you don’t intend to use this on the road or in severe off camber situations. If it were me, while less convenient, I’d probably install quick disconnect links. I’d hate to be a hundred miles from home and have the electronic one get stuck disconnected.
