I agree with everybody else. When i built my truck 8 years ago i started with 33's and 529's. It worked awesome!!! Over the years i went bigger and bigger on tire size and never had to re-gear it again. Simply can't go wrong with 529's if you ask me. In fact i still have both original gear sets in my truck. I highly recommend having them installed by a professional, i did and never broke a set. I have tons of friends that had a buddy or they installed them themselves and it seems they all have broke a set more than once. I'm a HUGE fan of doin work yourself but installing gears i leave to a pro
