i know xtreme suspension is 1.5 lower then stock, but im deployed now an getting a shopping list ready an dont want to get the wrong parts. i'm look for a good drop without scrap'n the ground. where an what parts? 3" is fine ..

belltech has a drop spindle of 2" but what would go with that? would i have to replace the spring an shock as well?

what about the back? i want it be level ride not one higher then the other.

 

If you want a 3" drop, You could do the Belltech spindles and a 3" coil. The 3" coil will lower it about an inch over your stock stance. I would recommend drop shocks but since the coils will only be an inch lower I wouldn't worry about it right away.
Get a 3" block for the back and you are done.

Make sure you order parts for 98+ blazer, Earlier years and S10 stuff will not work.
