I decided to verify my 3.55LS diff gears this afternoon before I detailed my '11 5.0 SCab. The LS tag was no where to be found. Has Ford stopped installing these on the newest body style F150 or is mine missing?

 

Now I'm going to have to check out mine!

 

im pretty sure it was a code on the door sticker in the 09-10. are you saying its not there or there used to be a sticker somewhere else and its not there like in past models?

 

It is inside the driver side door. It will have a code and you can look up the code online.

Sorry, I should have been a little more specific. I have the label on the inside of the drivers side rear door. Ford used to install a metal tag on the differential showing the gear ratio, as well as the door label.

I have one on my '68 Ranchero and '94 Lightning. My '92 Ranger, '95 F150 XL, '02 Stang GT and '07.5 STX all had them. They are attached to the differential by way of cover bolt.

I guess they're saving a few dollars that way. It's the first time I've seen a rear wheel drive vehicle without one

 

Great link. Thanks MGD. Is there a decoder that tells the actual axle model. Like Dana 50, 60, etc? I've tried Googling it with no success.
