What truck are you looking to level?
I have leveled a Ford explorer with torsion bars and it stiffened the ride some. Have also leveled a f150 with strut spacers and nothing in the rear and it didn't really change the ride.
I'm not really a fan of putting blocks in the rear. Level just the front to bring it to the rear height. Any more puts excessive wear on the front cv shafts if it is it's
I put a 2" level spacer on an 05 F150. I loved the look and was able to fit 33" tires under it(33 x 12.5 x 18). The ride didn't change at all at least not until I put on BIlstein shocks on then it got a little bit stiffer. With that truck I still had about 1/2" rack towards front. It didn't take much weight in the bed to make it look like the rear was squatting tho.
I currently have a 13 silverado and have been resisting the urge to level it. The only reason I'm resisting is that it will lead to larger tires and probably a programmer to adjust the speedo. I have kids now and it's hard to justify spending the money on a DD. Even though it did look pretty good

2017 Z71 what, you give us absolutely nothing to work with, you ask for help and don't even tell us what you need help with.
The Z71 package is offered on the Colorado, Silverado, and Silverado 2500/3500HD, all very different.
I will go out on a limb and guess you have a 1500 Silverado and my answer would be to buy the Bilstein leveling shocks, if those are to much money then pick the cheapest coil tower spacers you can find as they all do the same thing. Don't forget to get a allingment afterwards.
Because the Bilstein shocks offer 3 different height positions vs one with spacers. The Bilsteins offer a better/safer ride as there is no longer brake dive, sway, or uncontrolled rebound. You will find the stock shocks suck so this kills two birds with one stone although this is a expensive route as you should get the matching rear shocks.
Leveling kits are ok unless you actually put stuff in your truck, then it doesn't take much and you're driving around with your nose in the air which looks silly.
and please if you do level it, adjust your headlights, too. most skip this step and either don't realize or just don't care that to the rest of the world it looks like you're driving around with your brights on.

So does Bilstein shocks front and rear with the front slightly raised, and a set of air bags on the rear for towing sound reasonable? No loss in ride quality?
