I am considering lifting my tundra and putting larger tires on for cosmetics. For anyone who has lifted their tundra, are there lift kits/tires that will not void my warranty? If I do any lift at all, it will be a small lift (~3 inches) and larger tires. What am I looking at in terms of costs, and will I have to make any other changes to the differentials or steering column? I would appreciate any advice on this.
