Once you change the gears in your differential, you need a new speedometer gear to recalibrate your speedometer. They're inexpensive, and only take a few minutes to change.

These Recalibration Gears fit 1979-1998 Mustangs. Please check our Hot New Product Section for information on 1999 and 2002 Mustangs.

Instructions: Note transmission type, model and resulting drive gear. Cross reference with your rear-end gear ratio to find the correct "recalibration" gear for your application.
