I've had plenty of cars in the past that I was able to mod and not void warranties. I also never said I was mad about it and was only responding to the other post above mine. I also understand Chevy's stance on warranty issues on suspension and engine pieces, and that is fine. However if a person were to have a leveling kit or anything else done, and it is by a competent shop, then you would think that they would be a bit more friendly towards it. Enjoy your day.
