you ready for a novel?
I guess the main question is what you want to get from the air suspension?
Do you want to be able to drop your car to the ground? or do you just want to be able to carry heavy loads?
If you just want to carry heavy loads then those will work fine. The one you emailed me is just a helper spring, It sits inside your stock springs and works like an overload spring.
If you want to be able to slam your car to the ground, then this is not at all what you are looking for.
What you need then are acutual air bags that replace the springs in your car. There are several companies that offer such bags but the best by far are made by Firestone.
You will also need to get a compressor, an air tank to use as a reservoir and some form of switches to control the air bags.
This is a very expensive modification, It can cost up to several thousand dollars if you want a fast and elaborate setup.
I had mine in my car for a couple years and I slowly upgraded it unitl I had what I consider a great setup.
I could go on for a long time about this. I am more than happy to answer any questions you may have.
But one thing you need to realize...Volvo front suspension is a bitch to bag.. It will take lots of custom fabrication or an expensive set of custom made air struts.
Let me know if you want me to explain any more on the is subject.
Here is a link to show what I had in my car.
