how much is involved to put a 2 inch body lift on an 89 s10 blazer 4x4 and with the 2 inch lift could i run 31x10.5x15 tires

i had a 3 inch body lift on my old s-10 and it just barely fit 31's

A major thing to keep in mind... Guy I know did that to his Blazer, and it looked really sweet. But the engine had to work extra hard, and was extremely bad on componets. Wore out stuff premature, and then he took it offroad in the mud and was left afterward with a lot of weird/bad noises...But what you do with it is up to you. It will look cool though...
