Bilstein 5100 vs spacer
 

I have a 2016 Siverado 1500 that I would like to level. After much reading, it appears that the Bilstein height adjustable shock is the better option but gives just 1.85 in of lift. I am looking for closer to 2.5 in. Does anyone know if using a half inch spacer with the Bilstein will negate the positives of this shock vs just a spacer on its own?
