I just got a 95 blazer and i want to do a 2in lift i was told i could just raise the torsion bar so I'm wondering how many turns should i do before it is unsafe for the cvs and ball joints. and i i can do that could i just put a lift block in the rear

 

this can be found using the search feature the forum provides

there is many threads how to do a tbar crank successfully and how to lift the rear successfully
