You really want at least a 4.10 with 32 or 33's. Forget the factory
gearing because it was way too tall to begin with (it was that way to
try to sqeak a little more MPG out on EPA MPG cycle but not in real
world) If you use link below you will find a free online tire
size/axle ratio calculator that will shed a little light on you quest.
When you do the numbers remember that the lift and bigger tires
increase drag so it will tak more power to cruise same speed so simply
making same effective gear ratio as stock will not help MPG one bit.
You will take a drop in MPG because of lift and tires but you will
take even a bigger drop if you do not properly regear it and lug
engine.
