I've researched the net. I've read several threads on this forum. There doesn't seem to be a definitive answer. I'm getting ready to purchase a new '16 Sierra 1500 and want to add a 2.25 Inch Pro Comp Leveling Kit and 305/55R20 Fuel wheels on it. If I install the lift myself, will it void the warranty? Do I have to have certified mechanics install it to keep the warranty?
Any GMC Dealers or warranty specialists on here?
Thanks for the input.
