The Vehicle Certification Label on my 03 F250 lists the axle gearing as C3.

Does this mean it is 4.30 Limited Slip?

Thanks

Mikey

Oh & BTW this is a wicked site

 

The chart that I have lists the following axle codes for F250 through F550 trucks:

37 3.73 non limited slip
3L 3.73 limited slip

41 4.10 non-limited slip
4N 4.10 limited slip
4W 4.10 limited slip (ambulance package)

43 4.30 non limited slip
4L 4.30 limited slip

48 4.88 non limited slip
8L 4.88 limited slip

53 5.38 non limited slip
5L 5.38 limited slip

Where do I look for those #'s? The C3 was on the Vehicle Certification Label on the drivers side door post.

Thanks
