Speedo Gear Chart

[Mudderoy]

Here is a good chart from Morris 4x4 Center.
I have purchased several items from them.

It is recommended to replace the O-Ring Gasket Part # 6035709 when changing your speedometer gear

Hey Mudderoy,do you know if those gears are available from a local stealership?One more question.With the 31x10.50's on my Xj,how much difference in mileage calculation do you think mine is off?I still have the stock speedo gear in there as far as I know.:hmmmm2:

Waiting for my gear to come in from Morris 4x4 Center.

i need one. chyr 8.25 rear. goin from 28.5 tires to 31

I must be brain damaged or something, but I don't understand what that chart is trying to tell me. Am I to assume that the baseline standard speed is 30 mph or what? I know that my speedo reads slower than I'm actually going, but I don't understand the chart.

Do the descending numbers represent a part number? Like if you are running a 3.73 axle ratio and 33 inch tires you need a Number 31 speedo gear? Do they represent a speedometer reading? I don't understand.

Sent via messenger pigeon - i talk, he types.

[rabies]

so would be speedo read to high or too low with bigger tires without new gear?

[4.3LXJ]

Too low

[XJ Wheeler]

Yep, low. Mine reads right about 65mph when i'm actually going 70 (gps verified).
