If you are wanting to get bigger tires I think you would want at least 3.92's but if you have to change gears think about going 4.10's. As for cost I am not sure it is something I have thought about but haven't done a ton of research on it as I don't have the money to do it but it will depend on what manufacturer of the gears you are going to go with and then what the shop will charge you.
I submitted for a build sheet.. So hopefully I will have my answer soon.
