Twist in type spacers are useless. Don't waste your time or money.
I added 1/2" spacers to raise my front end an inch...because I like the look.
I have a pair of Global West 1 inch coil spacers if you're interested. Because of the geometry of the a-arms, these will raise your front end up about 1-1/2". I paid $52 for them...you can have for $25 plus shipping...if you want.
I'm a hobbyist. Not a professional. Don't be hatin'!
