I have a 2009 F150 Screw, short box, 5.4L. Has an original Ford hitch on it with numbers of "A439A", "10029BA", and "126-09L" stamped into the driver's side of it but I can't find those numbers listed online anywhere. Don't see any other labels or markings on it. Assuming this is a class III, but would like to verify. Anyone know what this truck would have come with? I do have the 7 pin wire harness as well, but no built in brake controller - not sure if that helps.

 

The OEM Ford hitch that comes with the Trailer Package is a Class III.

 

On my 2010 Screw the class is stamped on the reciever itself. Did you look on the reciever?

 

I did not see any other stamps, labels, etc on it. Where is the stamp on your receiver?

 

Actually it's a sticker, I was wrong. Yours must have fallen off.
