Hey guys...I have a question on the gearing of my differentials on my '12 JKU. The sticker says it is equipped with 3.21 gearing, but I also have the max tow package. Since i have the max tow package does that means it automatically comes with 3.73 gears even tho sticker says 3.21? I have heard contradicting info on this. Thanks in advance for the help.
