I have a 4.6 with a canned tune and just put on 33" Coopers and the truck came with 3:55 gears. I am going to re-gear but cannot decide between 4:10 and 4:30 gears. I have run gearing calculators and just cant decide. I am afried the 4:10 wont be enough of a change while I' worried the 4:30 will be too much. this cost way to much to do over so I would like feedback from people who have done this. My truck has the the 3 speed Auto with overdrive which is why I've been leaning towards the 4:30.

If anyone knows an affordable place to do the swap in San Antonio, I would appreciate it.
