I have a 1998 blazer. I bought it. With a full t bar crank and the person before me put air shocks on the rear and I'd like the lift the rear a ill more than the front but my blaze looks like its sagging right now it has 31s any advice on how to lift the rear just a little can I put blocks on it?

 

This has been covered lots!! Shackles or add a leaf are what your looking for. Blazers are SUA so putting blocks on would actually lower the truck.

 

How do I add a leaf?
