air shocks....to do or not to do

My Scamp had air shocks on it when i bought it (can't recall the brand but they were orange). Someone did this to overcome the fact that the rear leaf springs are shot. I took them off and put KYB's on, and now the rear is draggin ***. I have new MP heavy duty springs to put on, but have to tend to some other issues before I bother with that.

With the air shocks pumped up to correct the ride height, it was rough riding. Hit a bump and you jarred teeth loose.
