The only body lift I can think of is a 2" by performance accessories, and trust me, I looked.

 

I'm so confused in your first post you were looking to get the vehicle and now your going to sell it already so which is it? Take desert storm's advice and do the rc 2.5" and then a 2" body lift and be done with it!. NO you CANNOT do a 4 or 5" bolt lift! Nothing is long enough to reach as far as wiring, brakes, steering etc. I think the more important questions are what size tire are you trying to run and why are you specifically wanting 4" of lift?

 

I'm wanting 31x10.5r15. I know they'll clear with 2" body and 1" torsion. But I want 4" for the extra 1" of space between wheel well and tires. I don't just want it to look stock with 31s like a 3" would do, I want it to look lifted with 31s

 

Why are you going through all the trouble of lifting it if you're going to sell it?

 

How old are you?

 

Because I'd like the experience of building it but don't have the luxury of having a toy right now

 

If you can't afford a toy then why waste the money on lifting it? You aren't going to get more money for a slightly lifted blazer.

 

I beg to differ. I know the market in my area quite well. But I believe we're getting off topic. This was a question of HOW not WHY. So if you could help me figure it out Id much appreciate it. If you're going to question why, please do so in your head.

 

We've already told you how to do it! Just read around the forum and you will see what we told you to do is EXACTLY how 99% of everyone else has done it.

 

There is no such thing as a 4" suspension lift kit for Blazers. There is a 2.5" RC lift, and several different 6" suspension lift kits, and cranking your torsion bars more than 1.5" on a stock suspension will chew threw CV axles pretty quick. If you're set on 4" as the ride height you want, then the way Rex described is the best. 2" body lift, and 2.5" RC suspension lift. Changing the shocks will not affect ride height in any way. Other methods of lifting the rear axle are shackles (aprox $40-$80 to purchase) or add-a-leaf (aprox $60-$80).
