7 Tooth Speedo Drive Gear

If you have changed rear gears, or your old one is worn out this is a simple part that installs easily once you have your transmission apart.

    Is necessary to get speedo right for new rear gears

    I purchased new rear end gears and replacing the speedometer drive gear was required to retain the correct speedometer reading. Was a little work since transmission removal was required but not that big of deal with a little mechanical know how.

    PERFECT FIT

    It corrects the speedometer when changing your stock gears to 3.73. Easy to change when transmission is down.

    Speedometer Drive Gear - 7 Tooth (83-98 T5)

    just wanted to add something to the installation guide, do not forget to put the shift linkage coupling and spring & ball in the housing before the tail shaft goes all the way on, or like me you will be pulling it back off :( this is not in the Installation Guide

    Probably works with the T5

    This will probably work with the T5, but I have a T45 and nobody seems to sell this gear for the T45. I bought this thinking (for some reason) that it would fit the T45 but it did not. Other than the smaller shaft size, this gear is the same as it would be for the T45, so I chucked it up in the lathe and bored it out to have a 0.02" press fit over the T45 drive shaft. Pressed it on and it works great with my 3.55:1 rear end and 20 tooth speedometer gear. If I recall correctly the drive shaft outside diameter is 1.375" and I bored out the gear to 1.355" as I said before, it works great
