yes mine appears to be 9.75 rear and 8.8 front.
The only selectable diff lock I found so far is Auburn that works as limited slip when not engaged and fully locked when engaged. But Some people on the F-150 forum says it doesn't work as advertised. They just fail to work.
Any idea about...
I would like to re-open this discussion here,
I have a 2012 Ford Expedition, is the combination you mentioned is still up to date or did you find something better?
What is the gear ratio of my car ? is it 9.75" or 8.8" ?
What part number is the correct one for me and where to find it?
How about a 2012 ford expedition? Do you have any recommendation before I order it from Amazon? I am going to order ZEON 89120, but I need to know the precautions before installing it on my expedition. Please do review my topic and list your recommendations.
