You can go on jeep web page with your vin and get your build sheet. Or look on your window sticker I you still have it.

Most reliable way (unless you are original owner and know it hasn't been regeared--in which case above advice is spot on) is to jack up Jeep and count driveshaft revolutions as you turn tire. Plenty of YouTube videos on how to do correctly.

Jack one front tire.
Put a chalk mark on the tire, and one on the drive shaft.
Turn the tire 2 revolutions, while counting the turns of the drive shaft.
The number of drive shaft turns will be your gear ratio.

A little less than 3¼ = 3.21
A little less than 3
¾ = 3.73
A little more than 4 = 4.10

Easiest way is to go to the jeep.com website under -->Owners, Owners Site/Uconnect AccessLogin create an account and enter vin number. Go to the tab "Learn and Use" equipment you should see every option your jeep came with.
