Page 8 of your Warranty Handbook is pretty clear about what is and what isn't covered. You can modify the vehicle and it won't void the warranty, but those parts are not covered:
Installing non-genuine parts, components, or equipment (such as a non-genuine radio or other accessories), even if such components are installed by an authorised Dealer or other qualified persons.
Lift kits fall into the "Mods that may void your warranty" class. Using the word "may" implies that there is some discretion on the part of the OEM:
In the event that (a) non-Chrysler approved “lift -kits”are fitted to the suspension of your vehicle; (b) non-Chrysler approved suspension, driveline, engine or steering modifications are fitted to your vehicle; (c) non-original specification tyre rims are fitted to your vehicle, then the warranty will not cover these unauthorised after-market modifications or components or part of the vehicle that are damaged or need to be repaired or a direct or indirect result of the fitment or operation of the unauthorised after-market modification will void your warranty.
From my reading on this forum it looks like Chrysler will help you with your DWs up to a certain point and then pull out the "it's not our problem" card. Where the point is probably depends on whether you have been playing nicely with them.
