more lift?

I saw a guy on ebay that said he has a 4.5 lift and some other things running 35's. Can you add something to an existing lift? How much lift would you need to run 35's? I currently have a 4.5 rough country lift with 33's but I am wanting to run 35's eventually.

Trim your fenders, sprinkle some pixie dust, and magically you can run 35s

dont forget bumpstops

3 inches and 35s hes a member i will try to find his name as it escapes me
right now
