Hey guys if anyone has an idea about whats going on with my truck it would be much appreciated, so i recently got some new wheels and slapped them on, when i went to turn on the truck to take it for a spin, i got hit with “service stabilitrak” as well as the abs light. Nothing was wrong with my truck before so i dont know what couldve happened my guess is i bumped a sensor while i was in there but im not sure. Also my parking sensors wont work anymore when i click on the switch i just get a dim orange flicker for a dew seconds but they wont turn on, so i am concerned since it was just a change of wheels. Ive already changed wheels on it before so i dont know whats happening. My truck is a 2014 Silverado ltz 4wd

So i was looking into restoring me truck back to stock ride height and maybe add a leveling kit. It is a 2014 1500 silverado 4wd with a 3/5 lowering kit with springs and spindles in the front and a 5” flip kit in the rear and was wondering what it would take to get her back to stock so i can actually use the thing to its full potential. Any help would be much appreciated!
