Just installed 2.5 kit from Rough Country on the 6.2L Denali, includes adapter for Magneride, zero difference, aside from a solid rake front up 1 inch, left out the back block kit. The kit is designed for Magneride, spacers go in quick, even after you or the shop does installation, we got excited and forgot one side, then added by turning the wheel.
Only install the back if you want true level/slightly down front, otherwise enjoy an almost exact 1" rake looks awesome.
Here with stock size 275/55/20 Cooper Adventurer A/T tires on original rims, aftermarket tow mirrors cause the stole my leased 16' Denali's side glass off the street. The 15 has given a tire and mirrors now, but it got upgraded, so she's happy, as am I.
Get ROUGH COUNTRY!!!! Just know silver control arms are aluminum and black are steel, but there is also stamped on 16+ i think, also black, just skinny not original styled.
Out in Baja, Ensenada. Super happy.
