You can do it yourself,as long as you got some good tools.You really don't need air tools,we didn't.
It's very easy,you would be suprised.Hell if you were near me,or vise versa,i would give you a hand in a heart beat.
Here is a little tech to help you if you do decide to do it yourself.
What i did is take off the front tires,then unbolted the sway bars end links that connect to the control arm,unbolted the front strut(make sure you use a pump jack under the control arm for ease of lowering),pushed the strut down,and pulled it to the side,then covered it with a blanket so the strut wouldn't scratch the paint as it rested against the fender,then with a buddy,one will push down on the control arm,while the other pops the spring out.There is a bit of tension on the spring,so you need to be careful.Then put your spring iscolaters on your sportlines,then put your sportlines in the control arm(no need for effort,they just drop in),make sure you only cover the one hole in the pocket of the control arm,the other is for drainage for water,put your strut back in place,using the pump jack,then tighten the stut,and then do the same for the other side.Then bolt up the end links back in place.Done.
For the rear,take the wheels off,undo the sway bar,then un bolt the lower control arm where it is bolted to the diff axle,again with a pump jack,slowly lower the control arm,and the spring will fall out.Then put the spring iscolater on the top of the sportline spring(you'll need tape to hold it on),place it on top of the lower control arm(make sure the pig tail of the spring is facing the exact same way the factory one was sitting),then raise it back up into place with the pump jack,slide the bolt back through the lower control arm,tighten it up,then do the same for the other side,and then you can put the sway bar back on. Done.
Good luck if you do decide to go through with it!!
Like already said,its easy.
