Speedo Gear

[cubewhiz]

Maybe somebody can save me a trip underneath my truck.

I have a 1989 Ranger with 3.73 gear ratio. Does anybody know how many teeth are in the stock speedometer gear?

My stock gear is black and has 20 teeth. It had 3.73 gears and 215/75R15 tires from the factory ('90 Ranger, 2.9 M5OD-R1).

Depends largely on the stock tire size.

I believe the tires were stock at 215/75R15

Look on the tag inside the door, it should tell you there.
