Your warranty will be void in all aspect regarding the lift and anything that directly relates to it and can fail through the addition of the lift. Even if your dealer installs the lift, you will not maintain your warranty through a 3rd party part addition. The only exception is the Mopar Lift which is really a Super Lift with a Mopar sticker.
Most dealers do not install custom parts and don't want liability of such work because then you get into the fine line of "since dealer installed, it should maintain warranty". Your best bet is to get it done at a well known off road shop. They have much more experience and will do a much better job than your dealer who may have little to no experience with lifts.
Even if you install the lift and then your window motor goes bad, the dealer cannot state it is due to the lift and will have to repair it. Now if your wheel bearings go bad for whatever reason they may attribute it to the larger tire size and lift. Some dealers are more felxible while others are rigid on warranties. Depends where you go.
