I have a 1997 2nd gen blazer with 4x4 in it . I would like to lower it without taking 4x4 out. can it be done and how?...........shortstop_55@yahoo.com I have 20" on front 22" on back

 

Un screw the torsion jack screws in front. Blocks in the back prolly 2" . Might need to reverse the brake line banjo. ( Im not sure bout the 4x4 rear)

 

You aren't planning on engaging the 4wd, are you? Different size tires front and back effectively gives you different gear ratios, and that's really not good for your 4x4.

 

+1. Different tires front and back on a 4x4 is a good way to break things bad. I'd suggest that you disable the 4x4 by disconnecting the front drive shaft, or at least pulling the 4x4 fuse to make sure it isn't accidentally engaged.
