Hi guys...I am an owner of a Explorer 1992 and I'm registred to the explorer forum too on http://www.explorerforum.com . I just got a free diferrential because i wanted to got higher accelerations in uphill but ive found that its a 2.73 rear ratio.It came from a f150 so can you tell me what king of f150 it come from? than you guys because the f150 was all pressed :P

Are you sure its not a 3.73 ratio?

nortmally for an explorer its 3.73 for off road use but the one i got is from a f150 and the biggest gear divided by the smallest is 2.73 ratio. I know how to calculate a gear and thats 2.73... 41 tooth divided by 15 tooth.

That gave me siezures trying to read.

Congrats you can do simple math. As for what year truck unless there are some markings on it it would be hard to tell what it came out of. Is there a tone ring on the ring gear? If not then its older than 88

Sorry my bad english but thats not my first language
There are serial numbers on the biggest gear and the last number on it is 41.
Do you have a place to check the origin of a differential with the serial numbers on the gears?
It dont have the metal tag on the axle.

Thank you again

NGM

Not without the tag. There MIGHT be some numbers stamped in the axle tube that could be translated if its a Dana rear diff.

Ok thank you anyway ...It's my first 4X4 but i was sure that this kind of gear was reserved for hauling on highway. Anyway I will try to find a buyer in Canada for a higher gear.
Thank you
