I dont know to lift my 2wd 2in and put 31s on it or to put 30s on it stock? How much of a look difference does 2 inches with 31s actually make?

 

The closer to stock the better your suspension will work unless you REALLY know what your doing

 

So 2 inches wont be punishing my suspension parts hard? Because im gonna do 2 inch lifted coils and 2 inch lifted shakles?

 

Judging by the work Iv done on my 2wd the sweet spot is two inch lower. Camber gain and bump steer all got better. From the sound of your post I am thinking you're not too interested in making it better, just making it look more "Rambo". So to answer your guestion yes it will be worse. How much IDK, it depends on your values.

 

Mines a 4wd with 2"bl and 31s and here it us next to a stock 4wd

not a huge difference but definitely noticeable

 

welp,imma be that guy...


why put 30/or 31's on it? with it being 2wd. your accelerations going to die,more gas used,gear ratio will drop. Nothing beneficial. if it was 4wd,it usually comes with better gear ratios since its heavier and they know people are gonna lift/put larger tires on it.
( no clue what this means? google "gear ratio bigger tires"). i had a 2wd s10 once,i put 31" on it and noticed a huge power different in city. it sucked so bad i sold em and went back to stock. i hate bustin your bubble but thats the way it is.

 

Honestly if mine was 2wd I would have lowered it and gone for more on road performance like I think Chris is getting at. But you seem to have your mind set on lifting your blazer and that's your taste but to keep it streetable and if you dont plan on fourwheeling much a decent pair of 30's would probably look just fine without doing much to negatively affect you. Or trade it for a 4x4
