Putting a lift on void you warranty ?

[Klint]

Does putting a lift on your H3 void the 100,000 mile 5 year warranty?

[Hummer Guy]

only if GM (or the dealer) determines a certain part failed because of the aftermarket part...which with a lift kit, can be pretty easy for suspension parts...

The best advice I can give is to talk dirrectly FACE TO FACE with your service manager.

Mine told me will not affect any part of the warranty other than the parts I am replacing or if those new parts casue something to break.

Good advice..a lot can depend on your relationship w/ the ones making the call...
