Best Air Shocks for Raising Back end?

I too agree with the spring needing to be the adressed area and to get rid of the air shocks.

I'm a total cheap skate, and on my Challenger the rear tires lack just enough back space, so the tires would just rub the fender lip.
The thought of those air shocks bleeding out and cutting a tire at speed really gave me pause.

So i shopped "add-a-leafs" from Summit and by adding a rigid spring to my existing spring pack, my tires are safe and for somewhere in the ball park of 60 bucks at the time.
