Question Rear end

I am new to rangers, bought 2003 4.0 auto FX4 and tow package. Wanted to know how I can tell what rear end gear ratios I have on truck?
Any help would be appreciated!

Since you've got an FX4 model, I feel safe saying you've got 4.10:1 gears. To confirm, take a peek at your rear axle cover and look at the tag. Should say 4L10 88....that means 4.10 Limited slip and 88 means 8.8" ring gear(Ford 8.8" Axle). Or open your drivers door and look at the door jamb sticker. Under AXLE, what does it say? R7 = 4.10 8.8 Limited Slip. 97 = 4.10 8.8 open.
