I'm leaning towards a 2" SuspensionMaxx leveling kit for my '17 Denali 4x4. Goal is to raise the front end a bit like a 4x4 truck should have come from GM (don't get me started on all that I've done on that front,) and make it appear more in line with the rear. Don't think I need or want 2.25" or 2.5" level. My question is on the instructions from SuspensionMaxx saying to get an alignment afterwards. Is everybody doing this? Not sure if this is to make it ride correct or if it's for tire wear, etc? Also, do you have to do both front wheels off the ground at the same time? Can I do just one wheel at a time and loosen the nut on the sway bar?
