My experience has been that there is no “voiding” of a warranty on a vehicle for any reason (that would be illegal). IF something goes wrong with a related component in the future, the burden would be on MOPAR to prove that your mod caused the issue. They typically don’t want to fight this.
Also, MOPAR sells and installs leveling kits, so you could go that route if you’re overly concerned. It’s more expensive, but your peace of mind is worth something.
