aggie, it helps control vibration.. and most likely to some extent make some things last longer. 33"s are fine, will have to see truck with 33s and 3" lift. i run 32"s stock and they fill the wheel wells just fine. you could run 35"s though it may require a bit of trimming on the front.... who nees lift? i am just gonna cut the fenders and run 35"s.. i MIGHT..... eventually go with some fiberglass fenders...
as far as braking is concerned.. i havent really noticed much of a difference, as long as your brake system is up to par.
by the way here are pics of my truck.
