Sorry if this sounds like a stupid question, but I am new to the forum. I just picked up a 1995 silverado 1500 z71 extended cab. I want to do the 3"+3" torsion key and rear block combo kit, and a 3" body lift with front and rear bumper brackets. What else will I need to do this right, i.e.) shocks, springs, etc. Any help would be much appreciated!! Thanks in advance!!
