Thanks
@Big Mama and
@adventurenali92 for your insight. Initially I wanted an added inch of lift to the rears so the Billstein with Moog springs was my plan. I had the Billsteins put on the front at the highest setting to fit my wheel/tire setup, but I think I have room to spare and could lower down a bit so I wouldn't need any rear lift for appearance reasons. The ride right now is pretty rough and hoping the rear replacements will smooth it out. [honestly I'm a little regretting going to 22s with AT tires].
Now I am thinking the Arnott is a better option for the rears. I will research (just seems more plug and play). With respect to the Arnotts, is replacing the compressor also usually required? About 60k on this '16 Tahoe and the shocks are completely rusted out and need replacing for sure.
