Surprisingly not a lot of info out there on JK O2 sensor work. I'm throwing PO153 - O2 Sensor 2/1 Slow Response. Jeep has 108k on it.

Research (I think) shows Bank 2=Drivers side Position 1= Before Cat.

Problem: Finding the correct O2 sensors without going to the dealer!

Can anyone confirm the following?

Rear (after cat) sensors are the SAME for both 'banks' (Mopar #56029049AA)
Front (before cat) sensors are the SAME 'banks' (Mopar #56029084AA)

Thanks!!!

You can buy NTK sensors from any parts store. No need to buy OE. The MOPAR sensors are made by NTK. Do NOT buy Bosch, the Jeeps don’t like them.
