what size?
 

ive got a 97 blazer with a 3 inch susp lift and i want to put mudders on it. what is the biggest i can go without rubbing. i was wanting to do a 33x12.5x15. let me know what will fit so i can get spending my money lol.

How did you get 3in suspension lift. I have never seen a 3in kit. Unless you got torsion keys that said 3in. With 3in you might be able to fit 31s depending on if they are actually 31s and if you will be offroading. 33s are a definite no. I have that same size on mine and i have a total of 9in of lift and they rub once in occasionally on the trails

chackled in the back with blocks i guess and adjusted the bolts in the front i was told its 3 inchs lol but i know it sets higher then a factory blazer

the s10 blazer is spring under axle. so if you put a block in it will actually raise the axle off the springs which will make the truck set lower.

im ot going lower with this blazer its a waste to have a 4x4 on its nuts

you are the one who said it had blocks.... as said.. blocks lower the truck, like said,,, no one said to lower it, you said it had lowering blocks... seeins as that's what blocks due... get it..
if not look at your axle/spring perches and think how a block could possible raise your truck

and if your tortion bars are adjusted to give you 3" you are going to be changing front end parts on a monthly basis and wearing out tires like no other
