anybody know if you were to want only a 1" - 1 1/4" body lift on a 1999 Tahoe (old style) if you need a whole kit or can you just use 1 1/4" pucks. Will the steering, radiator, etc. need to be extended. I know for 2" and above it needs to be extended. I already have a leveling kit and 2" rear blocks with 315/75R16 MT and just want a little extra height.
