Most luxury sedans have this, most are automatic, those who don't have one
the owners might install it.
Why, if you don't mind not being so fancy, I used to have regular air shocks in
the back of a Thunderbird, however these are used more to adjust for stiffness
of ride than anything else, such as when carrying a load...
The point I am making, however, is these air shocks are inflated and deflated
like a tire, via a tire valve that the installer conveniently placed inside the trunk.
All it takes is a little planning, and adjust the pressure before going on a trip,
also it has to be checked about once a week or so, like tires.
How hard they are to install, I don't know, spending this kind of money I had it done.
The rear I hear say isn't so bad, which also that's the only place I had them...
Most folks wouldn't dream of putting air shocks in the front, I am not even sure
it can be done.
But I am doing front struts on another car right now, and I can honestly not
recommend this as a DIY procedure... It is somewhat technical but there is a
considerable danger factor involved, and you need special tools.
Also the amount of labor, specifically some parts have been together so long
they are real tough to get apart, even with pneumatic tools this has been an experience.
Several things to consider:
The price, I think I paid $400 installed and all...
But will the meek gains in FE outweigh even that?
Also, like I said, they're mostly used to adjust for stiffness, not height.
So I suspect the reason is hardly FE, why would someone owning a Lincoln
Continental Mark VIII care, there's a dog gone 5.0 V-8 under the hood...
