I wanted the rear of my sdl to sag less when loaded w/ extra fuel so I got
1)hd springs....no gain in height, just less loss of height w/ load.
2)hd bilstein shocks...about 1/4" gain measured at bumper.
3) 19 mm (thickest) spacer...gained 1 3/4"


then much later I replaced subframe bushings and gained another 1 3/4 inch....I had to remove the 3 nub spacer w/ the 1 nub.



does yours have sls?
