L.C.Gray Posted July 5, 2014 Share Posted July 5, 2014 From what I read my '11 F250SD has 2 possible axle ratios. I see a spot on the VIN tag marked "Axle" and "3E". How can I determine what ratio I have? Quote Link to comment Share on other sites More sharing options...

L.C.Gray Posted July 6, 2014 Author Share Posted July 6, 2014 Thanks. I was betting it was 3.73, knew it was the locker. Quote Link to comment Share on other sites More sharing options...
