Confused: Strut Spacer vs Torsion Keys

[Undeserving]

Ok, I am thoroughly confused. The more I read and the more vids I watch the worse it gets. There appears two ways to level a NNBS Tahoe/Sub: strut spacers (upper and lower) or different torsion keys. I have watched countless vids on each and want to know which is the better route to go in terms of leveling my 2017 Z71 Sub. Cost is not a factor and I will probably have a local shop do the work. Bilstein 5100 will be added at the same time.

Please educate me on these different methods. thanks.

Hopefully someone with more knowledge will chime in and correct me if I'm wrong, but I think your truck has coilover front suspension which doesn't have torsion bars or keys.

Edit: also if your truck is 2017, it's not NNBS, it's K2XX

Everything after 2007+ (I believe) had struts and uses spacers (*shivers* leveling kits), 2006 and older had torsion bars and uses keys or just tightening of the bolts.
