How much does it cost to get my 02 runner re-geared, what all exactly has to be changed...the gearing in the diffs?, i take it you have to take it to a shop to do it right? i was thinking about doing 4.88s cuz im only running 295/70/17 and would like to get a little more gearing power, also if i did a SC would it helped to be re geared or would the SC help me to not have to be re-gear. Sorry for so many questions, Thanks!
