Based on everything I have read, I'm of the same opinion as MTH. Mopar lift kits are considered performance parts. If the lift kit/mod causes something else to break/fail, then that particular part is not covered.
And like MTH said above it is record keeping. That way if you were denied warranty coverage based on a mod that you did and go to another dealer they know why that warranty claim was denied.
