Where can I find gear ratio?
I can't seem to find where is says what gear ratio my truck has or if it is a 8.8 or 9. Can anybody help me find these allusive numbers? I have a 2001 4.6L Supercab 4x4 4R70W. Thank you

You have an 8.8" differential. The 5.4L receives the 9.75".
The "Vehicle Certification Label" is on the drivers side door jam.
Rear axle ratio codes:
18 - 3.08
19 - 3.55
26 - 3.73
27 - 3.31
H9 - 3.55 Limited Slip
B6 - 3.73 Limited Slip
