Identify your gear ratio

[ElecTape]

I have a copy of the window sticker which says 4.10 gears. However I assume that when they add the 3.7 motor the gears are changed. How do I verify the gear set. Is their a tag on the drivetrain somewhere that identifies this?

When new there was but over the years it may have fell off
NO 3.7 came with 4.10 geraing, only the 4 poppers did
If 3.7 and automatic then 3.73s
You can request from Jeep your KJs setup when new , just send VIN and they are prompt about getting back to you

Thanks for the link. Yep 3.73 gears. I was confused by the Window Sticker I had for the vehicle which shows 4.10.
