Right now i have 2.73 posi rear end with a 700r4 tranny. I want to up it to like a 3.23 or maybe a 3.43. I also want to keep it posi. I was wondering first off, do i only need to by the gears or buy the WHOLE rearend?? And second do i need to do anything to the tranny or drivetrain?? Just a couple questions before i start buyin and gettin dad all angry with me. Thanks in advance

 

all you need isa gear set, it'd be a good idea too if you bought an install kit to go along with the gears. it might also be a good idea to read your manual a little about installing gears, there is a little more to it than just bolting them up and going.
