Lifting kit on an air suspension.

I am by no means an engineer, nor a suspension specialist. I have been a machine mechanic and machinist, among other things.

I have spent some time going through the service manual and examining my own Jeep.

It looks like it is very possible to do a minor lift, 1" - 11/2"(just a guess) to level out the front a bit. The "but" is that a deal will need to do the install to ensure the air suspension is brought back to spec.

What I think would need to be done is as follows:

Front leveling only.
1. Top spacer or longer front shock tube or lower attachment point.
2. Ride height sensor connecting rod/arm
3. Headlight and fog light adjustment.

the ride height sensor also adjusts the headlights. Head and fog lights have standard pitch and yaw screws, fogs only pitch.

A rear lift:
1: regular or Nivomat shock. 1 3/4" commercially available.
2: Taller spring or Airbag, or spacer for airbag. Spring is commercially available.
3: Adjustable trailing arm. (to center wheel)
option - Subframe spacers. (I have these on my subaru)

This is not a particularly difficult thing to do. I think it could complement the QL2 system with no changes to how it functions. Engineering and testing would need to happen to ensure axels and joints would not be compromised.

I would like to know what the rest of you think.

Re: Lifting kit on an air suspension.

There are already commercially available adjustment arms available to do minor height adjustments to a vehicle with QL for either "leveling" or adjusting the normal height stop point(s). I suspect these are more effective for lowering than raising because there is still a limit on how high you can go and it's already subject to slow speed and very limited suspension travel on a "bump". There is little else you can do to alter this suspension because if it's nature based on a number of threads on this subject over time.

Re: Lifting kit on an air suspension.

Both the front and rear suspensions are on cradles, would it be flexible to lift the cradles and space the top of the shock\struts?
