i got a 97 blazer and dont want to spend too much on a lift. are there any cheap mods i can do and what size tires would fit?

 

How much is not too much?

here is a 2" body lift for $135

But if you want suspension, it will be a little more expensive...

2" suspension lift - $430

2" of lift should be able to help you clear 31" Tires.
