Drive Gears / Speedo Gears
F100 - F150 - F250 - F350 - F450 - Bronco & GMC
Speedometer driven gears for automatic transmissions.
AOD transmissions use either a 7 or 8 tooth drive gear.
Once you change the gears in your differential or tire size, you need a new speedometer driven gear to recalibrate your speedometer.
They're inexpensive and only take a few minutes to change. We have 16, 17, 18, 19, 20 and 21 tooth gears.
The 16 tooth gears have longer teeth because they fit more than one application.
