99 K1500 Suburban needs a little lift

[BOWHNT]

I had a rough country 2-3 level installed, technically they refer it as a lift. Different upper control arms, differential drop bracket an some different torsion keys. I'm not 100% but I think if you cracked the factory ones you could clear 285s but I may be mistaken. I had 265 before the level and only swapped out afterwards.

I'very been planning to just do the torsion keys in front and blocks in back. Think that'll work?
