No problem at all with this exact setup. Stock snowflakes look great wrapped in 35" rubber and function flawlessly both on & off-road with the 6" BDS 2.5 DSC coilover kit using factory UCAs...

This is the only thing visible on mine (systems status via backlit led)....control box is hidden up under the dash.

You most certainly can use OEM wheels with the BDS 6" kit. If you have the Denali 20s then they are the same width as my 20" snowflakes, and I'm 99% sure the GM 22s are as well so you shouldnt have fitment issues unless there is something specific to the BDS Denali / Magnaride kit that I'm not aware of. I do have 1.5" BORA spacers on the rear not out of necessity but simply to even out the front/rear track width after lifting. No issues whatsoever with the Stabilitrak or other vehicle systems.

6" BDS lift with Fox DSC coilovers and 2.0 Rear shocks, BDS add-a-leaf. 35x12.5 Toyo MT rubber on factory 20x10 snowflakes. 1.5" Bora spacers in rear to even out with the front stance. No rubbing whatsoever and rides better than stock even before the Fox DSC Low Speed / High Speed adjustments are made!
