If i put new speedo gears in will it affect my gas mileage? I am currently running 33s with 4" of lift and 3:73s soon to be 4:56s. If so what speedo gear tooth number do i need?

Check this out. Might be able to help you.
-
well, no but yes.... if that makes sense.
if the speedo gear u have now is off, then your odometer is off also, therefore changing the mileage u THINK u are getting. so, changing the gear will give u an accurate mileage reading. but not really giving u better or worse mileage. -
dont follow the chart on quadratec...its not accurate. check other places online...i forget who i used but quadratec was off by a tooth or 2

If you find a different place let me know, I am looking at getting bigger tires with in the next few months. -
they may have finally updated it. i used this one from raingler..it was dead on with my GPS
looks like quad updated their chart...sorry for the confusion

How do you find out your R/P gear? I have a stock 06 TJ X.
-
Should be a metal tag on the diff with the gear ratio on it.
-
Cool thanks
-
if you're an X most likely 3.73
-
my 5speed 4.0 wrangler X had 3.03 gears
-
mine is a 06X Auto
-
you working tonight? i can take a look at it after roll call - 2300.
-
No, I am in MRM class till Wed. Funnnnn
Thanks thou. I will have to look sometime. I just crawled under and can't find any numbers.
Should be a metal tag on the diff with the gear ratio on it.The rear right ???
-
look closely around the diff cover on either axle. you'll most likely see a small sheet-metal tag affixed by one or two of the cover bolts. on this metal tag will be a whole jumble of letters and numbers...sometimes two lines worth. at the very end of all the stamped numbers you'll find the final 3 digits - usually a single digit, a small space, and then the following two digits. for example, you may see "3 07" or "3 73" as the last three digits. there are lots of variations that go into the final gearing at the factory - either tire packages, axle packages, engine sizes, transmissions, options packages, even special orders.
-
here - you can get the idea from these.

Found it. It reads as follows:
52132357 AA
3 73 2006230 6Does this mean I have 3.73 gears?
-
why yes it does...
-
ahhhh lucky..haha i crawled under mine a few months ago to put the locker in and found out that i had 3.07's...and im running 33's right now..im gonna have to upgrade the gears if not the axles because jeep likes to bog on big hills or when i punch it..its a good thing you have 3.73's because when you go to eventually get a lift and bigger tires you can upgrade your gears without changing the carrier
