I saw that also. I would not put any money on the assumptions made in that article. Basically someone saw an older concept vehicle on the road and surmised Jeep will offer this as a package from the factory. Sure would be nice but I don't see it happening.

I'm also doubtful, especially with the Trailhawk already on the road and filling a similar (although not exactly the same) market segment. The percentage of JGC buyers who seek that kind of accommodation, especially from the factory has got to be relatively small.

I do hope that colors like that might be available on the JGC in future model years...the same-old-same-old shades of grey is long past long-in-the-tooth, IMHO!

any info on how they got the 1" lift + 2" air suspension still? I wouldn't mind have a 1" lift but still the option to go higher in serious terrain

at a point it becomes more and more difficult to make a air suspension stable. imo at a certain point you're better off going with a hydraulic suspension. And I'm not really meaning overall height, I'm meaning range. currently quadralift has, what? 4" of difference between the lowest and highest ride heights? At a point, the differences get to a point where hydraulics are more practical(and stable), for say, like 7, 8 or more inches of difference between lowest and highest, nevermind reliability factor. That's why everything heavy machinery, themepark rides, etc use hydraulics.

So, is there no way to get bigger tires on a Trailhawk?
32" is about the diameter limit for the platform without body modification and dealing with spacing to avoid issues when the front wheels are turned.

I wonder if someone could simply make a spacer for 1" to somehow position on whatever the QL mounts to. Then utilized the LLAMS controller to modify the signaling to the computer in hopes of tricking the suspension into not "correcting" the height. In Theory you wouldn't lose any sort of travel as the suspension is being lifted by the spacer and the LLAMS would think its sitting at NRH. Then you could move the LLAMS into Low or Medium suspension settings which would essentially give the lift you want. Surprised no one has done this yet. My LLAMS is shipping currently would be interesting to see if this would actually work as I am thinking.

I think it depends on why we are running out of suspension travel. If it's because the air bag is pumped full and can't be pumped any further the spacer should remedy that. If the suspension travel is just tapped out regardless of how many spacers you add it may require some reengineering. Longer control arms? I don't know. I guess one way to find out is put a cheap puck under or on top of the air bag and see what happens. The systems will warn you if you go too high. Post pictures and take plenty of measurements. I'm not aware of anyone trying it so far so you might be the first. Best of luck and keep us updated.

We will name the new thread in your honor then steal all your ideas anyway. :thumbsup:

Correct no spacer exists. The controller from LLAMS does however. This is all just hypothetical by the way. I just read a lot of threads and looked at pictures of the suspension. Seems the biggest issue is like what has been mentioned anything over 2" from the QL alone means VERY LIMITED suspension travel and a harsh ride. So my thought was simply to create/add a puck somehow to attach where the bag attaches to so that you can increase the height by 1" or even .5". This normally from what I read would cause the suspension to freak out because it thinks its higher than NRH and it would deflate the bags to get to the expected NRH. This is where the electronics from LLAMS would come into play. The LLAMS could simply tell the computer "all is good" and now you are sitting 1" or .5" higher than normal. Once that is complete, then you adjust the LLAMS kit to Low or Medium which would inflate the bags to sit at OR1 but trick the computer into thinking its NRH so we would have 0 speed restrictions and we would not be sacrificing any more suspension travel then we normally would at OR1 Setting.

Anyway this is probably just a pipe dream, but would be cool to see if its possible. I dont know how the bags mount to the body and if a small aluminum puck could be milled to fit.

Keep in mind that the air suspension merely adjusts the height "in the moment", but it doesn't change the bottom and top suspension travel limits for the springs and shocks. That's why OR-II level is limited to 25 mph and many folks agree that 5 mph is more like it. Hitting those stops isn't a fun thing, particularly for your kidneys. :)

There are multiple discussions about this in the Suspension/Driveline/Brakes/Wheels/Tires sub-forum up above, including both the sensor links and the LLAMS being part of those discussions.
