First, congratulations on your new Dodge)! Under the Magnuson-Moss Warranty Act, your lift kit will not automatically void your Dodge warranty. That said, it will cancel certain aspects of your warranty due to the added strain that the lift will place on parts of the suspension and drivetrain.
This means that you’ll be responsible to pay for repairs to your suspension and drivetrain if you decide to get a lift, but the rest of your warranty will not be affected.
