Gear Ratio Help

[Rolltider67]

I was wondering if anybody has changed the gear ratio in their sport trac. Mine came with a 4.10 and I do not do tow anything other than a utility trailer. I was thinking about going to a 3.55 or 3.73 to help gas mileage. Any suggustions would be helpful.

I have the 3.73 stock and with the stock 235/70R16 it's not a record maker but you have enough under the throttle to get out the way. Even with my 265/75R16 and the 3.73 it's road worth but definitely not a hauler or off road rig.
