    Questions often arise regarding use of aftermarket parts like exhaust, suspension, engine etc. and how GM (or other mfgs.) warranty their vehicles. Here is the Federal law that governs manufacturers warranties.
    So don't hold back on modifications to your new vehicle fearing that GM will void your warranty. Mods away!

    My GM service guy told me when asking that same question was that they will not warranty any parts directly effected by my lift like if I had a hub go bad, it would not be covered. But, if I had something go wrong like my A/C was not working, my lift did not attribute to that problem so it would be covered.

    Everything would still be under warranty except for the parts directly effected by the leveling kit. Do what I did and go talk to the guys in the service department and they can answer your questions. My service guy even said programmers are great but be sure to set it to the stock tune before bringing it in for service in case they need to update your ECM. He refered to a guy that his ECM locked up because he had some kind of tune in it when he brought it in for service and it cast him $1500 for a new one.

    wow kind of nice to read these things but that all goes back to your dealer i would think. Some of those guys can just be straight pricks when it comes to warranty stuff.
