Trax

Need help. About two months ago I installed a 2.5" Rough Country Leveling Kit. I had the front end alignment done, truck has been driving great. Yesterday the "Service Stabilitrak" light came on as well as the Anti Locking Brakes. Got to my destination, parked the truck. When I left the lights were off. They came back on while I was driving. I am running the stock wheels and tires. What do I need to do to correct this. I am planning on putting bigger tires on in the near future.
