The ABS and traction control both use wheel speed sensors to function. In this case, I suspect when the leveling kit was installed on the front of the vehicle, they have one of the sensor wires stretched and it's losing contact until you straighten the vehicle again.
The wheel speed sensors are behind the front rotors. If you look behind the front tires/front brake rotors, you will see a wire running to the hub. Inspect that wire for damage and make sure it doesn't pull when you turn. Also, if you follow the wire, it will come to a connector. Make sure the connection is tight and not damaged.
I attached a pic of the sensor location. Both front wheels will have one, so check both sides.
Let me know what you find.
