F150 Heritage, 2004 extended cab 4.6L
The code is 27 but from all the door sticker decoders I find that code only appears for a F250.
I don't understand?
Can anyone shine any more light on this?
Any help would be appreciated.

Bought the truck used, it was a govt. truck.

 

I've got a 2000 with the same axle code. 3.31 open. I haven't seen nearly as many with 3.55's. But mine was also custom ordered from the factory with that ratio for some dumb reason. I swapped 4.10's in mine.

 

I stand corrected.

Gubment truck may explain the gearing.
