R230 ring and pinion available in a higher ratio is in the Armada. The two ratios are: 2.93 (Standard) and 3.35 (In the off road/tow package). I need to determine if they are interchangeable (and don't have some diifferent characteristic that would negate a swap), and if they are then there are some higher gear options available to those who want to change their gearing in that direction.
