I am thinking about buying a F150 XLT super cab 4wd but the axle I am not sure which one to pick there are 2 to choose from.
1.3.55axle ratio w/limited slip differential (xh9)
2.3.73 axle ratio w/limited slip differential (xb6)
any opinions would be appreciated
Thanks in advance ,

I have a 2011 XLT screw with the 3:55 limited slip. This ratio is kind of the best of both worlds. Good highway fuel economy and you still have good power for heavy loads or towing. The higher the ratio goes you can count on less fuel mileage on the highway. But you will be quick from stoplight to stoplight and you will be able to pull stumps out.

If I were buying a new truck with the 5.0, I'd go with the 3.73 ratio. All things considered, it is not that great of a difference.

 

My opinion has not changed. Always the highest number for a gas motor.
