shocks

I had a set on a roadrunner years ago and it picked up the rear a little and the ride was good. I did put new springs on it about 2 years ago, but it still has a sag. Should've went with the 1 inch over stock instead. I didn't want to remove them to have them re arched or replace them. If these shocks help a little, great if not no biggie, but I'm sure it will ride better than the air shocks that are currently on it. Also want something that will allow the rear suspension to work a little better when I get it to the track for some fun.
