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

well the rear would need a flip kit to use blocks cuz the springs run under the rear end and as far as the torsion bas i would just buy a 2 1/2 lift kit this will keep things were they need to be the torsion bars method will sag after time the ball joint angle and cv angle will be off and you will still have to get it to the aligment shop i lift kit will run you about 425-500 and then some time to install it depending on the tools you have and the help you have and mechancial know how
