You're taking the dealer too seriously, Bill. Go ahead and regear, and don't lose a wink of sleep.
NOTE: The following information should not be considered legal advice. For legal questions regarding the Magnuson-Moss Act, or to find out your legal rights regarding other warranty related issues, we recommend that you consult with a legal professional.
The installation of aftermarket components on your vehicle does not directly void your vehicle's warranty in the United States. However, your vehicle's warranty does not cover problems with aftermarket components, and your vehicle's warranty does not cover problems directly caused by aftermarket components. In the event that a problem with your vehicle is caused by an aftermarket component, your dealer must provide sufficient evidence of this to legally deny warranty coverage.
For instance, if you were to install a suspension lift on your vehicle, the rest of the original equipment systems on your vehicle would remain covered under warranty unless the aftermarket suspension was proven to be the cause of a problem. Your aftermarket suspension would most likely be covered under its own manufacturer's warranty.
These rules are set by the Magnuson-Moss Act, the federal law governing warranties on consumer products. Follow the links on the bottom of the page for more information.
