Air Shocks

Air shocks can be used without the world coming to an end. Are they the best way? Probably not. As long as you don't pump up really high, they will still ride good. If all you want is to raise the rear of the car a few inches, you will be fine. Now, the flip side is, if you ever decide you want to race the car, air shocks do exactly the opposite of what you want there. So just keep that in mind and you'll be fine.

...and I had forgotten about the Hurst Super Shocks. That brought back some memories. If you can find a set of those, those things are really nice.
