Re-gearing (or correcting the gear ratio after moving to a larger tire) is one of the best investments you can make to your TJ. You often don't realize you needed it until you've had it done. Then you find yourself asking "why didn't I do this a lot sooner?"I was debating updating gears to 4.88s but I have the 4.0 and manual and she doesn’t struggle on the highway so I don’t feel I really need to at this point.
