Every vehicle has a weak link. Whenever you change something (ie bigger tires) you cause something else to be stressed. Having built many Jeeps I know this to be true. Ford can't just stick on bigger tires without testing and improving other things that might fail. It just depends on how you will use the mods. If it is a mall crawler you can do just about anything. The biggest reason things get changed on a production vehicle is because the factory had to replace a faulty part/design under warranty, and they don't want to keep on doing it. They would rather put a heavier duty part on in the first place than have to replace a part under warranty. Do they make more money on upgraded vehicles, yes. But usually the consumer gets a better deal than taking a cheaper/lighter vehicle, throwing away parts you want to upgrade and then spending money on the upgraded parts. No warranty and not tested like the factory would do.
