First we have shocks all around even though some places call them struts
The Revtech/Daystar etc is the worst way to go when using " used" springs may work for a short time if brand new
New springs is by far the best way to go
OME and Ironman are both good springs to use
As far as how much lift , you'll get about 2.25 or so with just say OME 927s/948s , if you want more the thats where you get into adding a clevis , 3/8 inch gives you 3/4 inch lift, 1/4 inch top plate gives you 1/2 inch of lift etc
ITS all been gone through 1000's of times before on here I know
I was going to explain all of this to you if we met up when I came down but ................
