Airride suspension lifts?

Whats up forum people! I have limited mechanical knowledge and need some help. I am looking at buying a used 2016 or new 2017 Jeep Grand Cherokee in a limited or better so that i can get a V8. I also would like to add something like a 4" suspension lift and tires to go with. I am not interested in just a body lift. The problem i have is that it seems as though most all 2016s and 17s limited and up come with air ride suspensions. So these are my questions. Can you get a lift for air ride?
Can you replace air ride with spring suspension?
If so how will it affect the vehicle and is it a good or bad idea?

I spoke with one 4x4 place and they did not recomend doing so. So is someone one who dosn't have unlimited money screwed if you want to lift a newer Grand Cherokee?

Thanks guys/gals

Re: Airride suspension lift?

Well no need to worry about a body lift, since there's no frame. The Grand Cherokee is a unibody, so you couldn't do a body lift even if you wanted to.

That said, I think the air suspension (Quadra Lift, aka QL) is standard on all 4wd GC's with a Trailhawk or higher package. On 2wd models, I think it's optional though. Maybe someone can help me out there and verify.

As for lifting it. Unfortunately there's not a lot of options. I raised mine 1", but you can probably go up to 2" if you push it. This is done by "tricking" the QL sensors into thinking the Jeep is in a different ride height than it is. There are two methods of doing it, one mechanical, one electronic. Both do the same thing though and fool the Jeep into staying in a higher ride height while in "normal" mode.
Aside from that, without getting into completely custom suspension stuff you're out of luck with these. I don't think I've seen any with a 4" lift.
Also, just a heads up, without getting into custom stuff, you're looking at 32" tires. I've got 255/70/18 on mine (32"). You may be able to squeeze a 33" in there, though I'm just guessing. Point is, you're not squeezing 35's under these without getting creative and/or doing some trimming.

No lifts available for the GC with air suspension. Body lifts aren't an option as this is a unibody vehicle.

Re: Airride suspension lifts?

Soooo... why can't spacers be installed above the existing springs, then use different links for the height sensors to correct the sensor position?

No idea. If it could be done, someone would have by now.

The biggest majority of Limited's do not have the air suspension. They only come with air suspension if they have the off road adventure package.

Re: Airride suspension lifts?

No Lift for Airrides would involve extending the Air lines I would imagine and modifying the sensors.

Re: Airride suspension lift?

No idea how much it would cost to make a custom system but I'd assume it would be pretty expensive. It would have to be a one of a kind set-up, so surely not cheap.

I understand the concept you're thinking with the spacers, as I've seen/done this on trucks with standard suspensions. Also different links CAN be used to correct the sensor position. That's actually how I raised mine 1". By tricking the sensor into thinking the Jeep is 1" lower than it is, it raises it 1" to return itself to what it thinks is normal height.
Assuming you install a 2" spacer, or new/longer struts/springs (for a random example), you could then adjust the link to make that 2" height adjustment be the normal height. Sounds logical enough, though I'm sure there's a reason no one has done it yet.
I know there is not a kit marketed to do what you're considering because I had the same thought, and looked for one too. I don't know if it's due to a physical limitation on the system because of the air lines, or maybe an issue with steering or driveline linkage. If you develop a working configuration that allows some lift to the WK2 you can certainly market it. Heck, you can put me on the list of interested buyers.

Re: Airride suspension lifts?

When in the standard highest setting of off road 2, the suspension just about hits the bump stops and the air shocks are maxed out making an extremely rough ride. You will first have to come up with a way to give more suspension travel to the stock suspension. You will then need to come up with taller air springs. Different companies make air bag systems, find the one that will work. Since the current set up is tied in with the computers you will need to figure out how to disable all the warnings lights you are going to get when you disable it. Of course, you can just cover those air suspension service and warning lights with electrical tape and forget about it. It can certainly be done, the question comes down to how much money do you have, do you know where to locate the resources you will need, and are you smart enough to figure out how to do it. I would love to see it done and hope you'll post your build thread here as you accomplish it. Go for it!
