Bilsteins have the option of different dampening levels in the 5100 line. Everyone else only has one option per se, just keep that in mind. These numbers aren't for the trailblazer OEM yellow and blue bodies Bilsteins HD's, they are longer than stock for more articulation of the rear axle.
(255/70) 33-185552 - Stiffer
(195/70) 24-185783 - Tahoe replacements
(175/60) 33-185842 - Softer
Everyone has their own preferences on ride quality, I don't like soft sloppy rides which is why I run the higher valving rate to control the stiff spring rates of the Z71's. I rode in a TB with Z71's and the white body BDS shocks and that rode terrible, felt like a truck with 100k miles on original shocks.
