By nature being a gearhead lends itself to being a little geeky. We’re all into part numbers, VIN tag numbers, axle ratios, cubic inch displacement, basically lots of stuff no one else cares about. This website falls right into our car dweeb wheelhouse. We first saw mention of it on our forum section and we decided to follow up and were blown away by the amount of info we found.

Kevstang’s Ford Nine Inch Differential Page is the be-all, end-all website on the Ford 9-inch rear end. The amount of factoids and figures jammed onto this one page could quell the hunger of even the most hardcore driveline nuts you’ll ever meet.

History, specs, identification help, you name it, and it is there. We can hear the 12-bolt guys gritting their teeth.
